BBHs

The backbone hubs are the main structure of the network. Constructing them is one of the hardest tasks on the map, as making properly balanced hub can be made in many different ways and requires some basic knowledge.

There always used to be two types of BBHs, and those are 4-ways and 3-way which are furtherly divided by the amounts of lines they accomodate. Other hubs are junctions of strange types, like half-junctions, more than 4-way junctions or junctions with some special purpose.

LL RR Backbone Hubs (what is that?)

4-way Backbone Hubs (what is that?)
Date	Screenshot	Specification	Description	Creator	additional
19.1.10		Swapped over	A true masterpiece among 4-way hubs. This hub removes the worst connnections by swapping to left-hand traffic in the center. As a curiosity, it is the last hub Mark built before he left to Australia.	Mark	Download PSG #173
15.4.12		Chaos	This 4-way hub was built from scratch after two 3-way hubs merged to an unhandy mess. The tracks follow no particular layout.	XeryusTC, mfb	Download PSG #232

10.11.08		4 1-way lines	This hub is consisting of 4 1-way lines, of course 2 going in, 2 going out. The style of mergers is by using the bridge split.	intexon	Download PSG #193

SLHs

A sideline hub is a place where the main line junctions the side line. This means that we expect the side line giving priority to the main line and the side line has to be able to join any of the ML rails. A SLH is the easiest of our hubs to build. In general, their construction depends a lot on the shape of the main line - be it a straight ML, diagonal ML, corner ML or even spaces between ML lines matters. In the very old times there used to be built SLHs without priorities or without ability to join every ML rail. You can find those SLHs under Old SLHs and the proper rest can be found in the New SLH group.

Old Sideline Hubs (what is that?)
Date	Screenshot	Specification	Description	Creator	additional
18.03.07		T	"Fit-in-a-landscape"-SLH. It is a SLH since we didn't build real Mainlines for cargo routes in this game. This SLH is small but leaves enough waiting space in every direction.	Mucht	Swiss Inc. in the Archive
19.03.07		T	Nice SLH. Notice the absence of Loadbalencers but the implementation of Prioritizers. Large but fast. The X-Crossing in the bottom left corner is not good though.	Doke & Gamer	Download Savegame
19.03.07		T	Nice SLH because of the small size. Trains can take it on full speed but there is slightly too less waiting space which causes trains waiting on red signals may block other tracks as well. Also, this is unbalanced and unprioritized.	hylje	Download Savegame
19.03.07		T	Easy to understand, easy to build, clean style and fast speed are the advantages here. No Loadbalancing/Priorisation.	hylje	Download Savegame
19.03.07		T	This one was possibly not easy to build due to its geographical position up on a hill. It gives the Mainline traffic priorisation over the joining trains from the Sideline.	Walle	Download Savegame
19.03.07		T	Fully prioritized Mainline.	piratejerk & Walle	Download Savegame
18.03.07		4-way	Long time ago, Xahodo built this 4-way SLH. Notice: this SLH is unbalanced.	Xahodo	Download Savegame
07.07.07		4-way	strstrep built this 4-way SLH to service most of the stations on the old moneymaker line in the game. Note that this SLH is unbalanced (no access to 2nd ML)	strstrep	Public Server Game #46 (not available yet)

New Sideline Hubs (what is that?)
Date	Screenshot	Specification	Description	Creator	additional
11.01.11		Corner SLH	This hub is based on directions each connection has. Four connections(west split, eastbound join, east split, westbound join), four directions(NE, SW, NW and splitting to east, SE).	V453000	Download PSG #186
11.01.11		Diagonal SLH	A SLH on diagonal/mild corner ML showing how ridiculously small SLH it is possible to build.	Vitus	Download PSG #191
11.01.11		Fast joiner	SLH built with emphasis on exactly 1xTL waiting bays which allow to have full speed choices. (only westbound part)	V453000	Download PSG #204
11.01.11		Invisible SLH	An extremely compact hub using the technique called invisible because a big part of the hub is not visible at all - hidden in tunnels.	V453000	Download PSG #206
11.01.11		Classic SLH	A typical SLH with emphasis on system and order.	V453000	Download PSG #206
11.01.11		Half-SLH	A hub with one missing joiner. Main focus is the PBS -> 2way entry signal joiner which provides good choosing and minimum trains waiting at prios.	V453000	Download PSG #225

Mergers

Mergers are the most important part of backbone hubs and often decide the way how such a hub works. There are quite a few ways how to make a merger. With increasing number of output lines the merger building varies a lot, so it is divided by this aspect.

Detailed explanation of merging tracks can be found here http://wiki.openttdcoop.org/Merging_Tracks

Mergers with LL output (what is that?)
Date	Screenshot	Specification	Description	Creator	additional
6.6.10		Inner mix	A merger where the two inner tracks choose from the outer tracks, having all (two in this case) choices, saving the two lines from any merging or interruption.	V453000	Download PSG #186
6.6.10		All to all	As the name says, all lines get to choose from all destinations.	ODM	Download PSG #206

Mergers with LLL output (what is that?)
Date	Screenshot	Specification	Description	Creator	additional
15.04.08		choice	"3+3->3 Mainline merger fit into landscape. For the Northern lines a choice of all the three other tracks is offered. Update: important to note the lack of waiting bays replaced by combo-signals which can lead to trains waiting in incorrect spots	pm	Download PSG #74
24.7.10		Mix inner	A nice merger which leaves two outer lines to their own fate and works with the inside. As the two outer line only make for 2 output lines, one is "rather randomly" added as the inner lines merge to make for the 3 line output.	Mark	Download PZG #10
24.7.10		Sequential split	This merger built by XeryusTC uses the first split to decide whether the train goes to the first line, or somewhere else. If somewhere, then it splits there again to see if the next line is free and then again until all lines have been checked. This merger style can have problems if the incoming lines have high traffic but is very universal and can be used for basically any amount of lines.	XeryusTC	Download PSG #190

Mergers with LLLL output (what is that?)
Date	Screenshot	Specification	Description	Creator	additional
6.6.10		Limited choice	As making a merger for 4 lines gets to be quite large, hard, time consuming and possibly unexpandable, here we have a 4 line merger with not all choices. But despite that, the merger worked nicely showing that it might not be totally required to always balance everything possible. Of course you need some luck to have unbalanced things work though.	Mark	Download PSG #142
6.6.10		All to All	The strongest of the Brainmelter's mergers with an output of four lines. Every line is given all choices to all outcoming lines.	V453000	Download PSG #186
6.6.10		Downhill	A fairly nice merger but the main part of interest was the very end of it because it was built on a steep downhill to vastly improve train acceleration.	V453000	Download PSG #213

Monster Mergers (what is that?)
Date	Screenshot	Specification	Description	Creator	additional
6.6.10		A into B	An expandable, simple to build merger allowing full-throughput line towards all choices, therefore working very well.	XeryusTC, mfb	Download PSG #210
6.6.10		Shift	This merger is based on shifting trains to one end similarly like SML does. As a difference, this merger lets trains stop in waiting bays unlike SML is designed to do. To prevent trains waiting in waiting bays without a reason while they will never be able to join the line anyway, we used PBS and 2way eol so that the trains tried to join the line if there was at least a small chance to join. The merger ended up taking a large amount of space in length while saving some space in width. The instantly accelerating trains were key to make it work as well.	V453000	Download PSG #216
30.11.11		Inner merge	A nice example of a merger which makes use of the merge inner, keep outer lines.	mfb, Vinnie	Download PSG #210

Stations

Stations are often the place of interest, since there are so many ways how to build one. That is not only because of the various designs, but also because each station could have different purpose. Starting with recognizing pickups from drops, followed up by combined stations where trains both load and unload - just like pax stations, transfer or even refit complexes. Sometimes, stations are given some extra features like an automatic packer, which makes them special. Last but not least, most of our stations are usually enhanced by some nice eyecandy, some actually having more candy than station.

Basic Stations (what is that?)
Date	Screenshot	Specification	Description	Creator	additional
27.07.07			RoRo entrance for a 2-lane ML.	s_m_w	Notice that trains on both lanes can access all platforms
13.08.08			Balanced Presignal Bypass Station	thomashauk	A combination of the two above, the diagonal lines in avoid sharp corners. Notice the PBS for the balancer and the room left for queuing.
16.04.08			RoRo exit for a 2-lane ML. Notice that trains from each platform can enter each ML. Also they have a complete TL before the "X" so that a train can always leave the station properly before it may stop again	planetmaker	Public Server game #89
2009-03-12		Pre	Basic Pre-signal Terminus Station	KenjiE20	Very low throughput
2009-03-12		PBS	Basic PBS-signal Terminus Station Note the lack of signals on platforms, PBS takes care of that automatically	KenjiE20	Moderate throughput
2009-03-12		PBS	Mildly complex Multi-line Terminus Station NOT recommended under normal circumstances, but when space/money/Terra-forming is an issue this can be a good stop-gap Note use of only diagonals to avoid blocking from crossing trains	Thijs --TBC	Should set path_backoff_interval=1 or 2 if you use this
2009-04-14		PBS	A highly flexible Single or Multi-line Terminus Station Can be fit around the landscape with relative ease	Unknown (Various)	Moderate/High throughput
03.12.2009		Osai Terminus	Typical terminus without an X.	Osai	Download PSG #106
03.12.2009		2way eol	An extremely simple drop station to build. Has no balancing but can have any amount of platforms while keeping maximum throughput. Braking spaces in front of platforms are essential.	V453000, ralph	Download PSG #186
03.12.2009		PBS + 2way signals	A relatively simple yet interesting station using PBS and pre-signals. The PBS is used on the first split to make it not ask whether platforms are full, but whether spaces in front of PBS are empty. The PBS was required because the right choice would not fit a TL3 inside so the half tile PBS provided was needed.	V453000, intexon	Download PSG #196
03.12.2009		Combo signal X-less terminus	Osai's station copied in psg 198. It has a big disadvantage of using multiple combo signals for one block thus is possible to block if two trains go to the same destination.	Osai	Download PSG #198
03.12.2009		Basic overflow	Very simple to build overflow useful for small primary pickups which gained it's popularity very quickly for being small and simple.	V453000	Download PSG #209

Drop Stations (what is that?)
Date	Screenshot	Specification	Description	Creator	additional
11.01.11		2way eol	The 2way eol feature plays a key role in this station. Trains try to join a platform and the 2way signals divert them if the platform is full.	unknown	Download PSG #131
11.01.11		PBS semi-balancing	This station looks very messy but due to the fact that it allows trains to choose from many paths, it works. It does not allow all trains go to all platforms though.	Chris_Booth	Download PSG #136
11.01.11		Tunnel Exit	In the exit of the station tunnels are used and another set of platforms is fit in there. This not only looks awesome but it also uses the tunnels as waiting space behind platforms for trains so the exit is faster.	tneo	Download PSG #142
11.01.11		2 sides	This technically is quite a normal station. But the key difference is that it is halved and each part enters from one side, making the entrance much smaller and thus work much better.	Farden	Download PSG #156
11.01.11		Symmetric Terminus	Technically simple unbalanced terminus, visually a truly wonderful station.	ODM	Download PSG #147
11.01.11		Unbalanced Terminus	A nice terminus station in a cute shape. As it uses a single entrance signal, it uses penalties (the road crossings) to make trains prefer platforms which are far away from the first split aka the so called valhallasw style.	^Spike^	Download PSG #156
03.12.2009		Packer Exit	A special drop station featuring a packer based on using slow bridges to get trains in correct positions.	Osai, ^Spike^, Phazorx, V453000	Download PSG #170
11.01.11		2wayeol in V shape	A terminus using 2way eol, having balanced exit and being in a special shape.	V453000	Download PSG #175
10.08.11		Ultimate Mess	An extremely messy station which actually worked which ended up being quite incredible.	OwenS	Download PSG #177
10.08.11		Balanced Station	A balanced station with a bit atypical yet working entrance.	XeryusTC	Download PSG #184
10.08.11		Halved overflow	A special station consisting of 2 parts. Trains try to pick a platform on their part and in case they fail they move to the other part. This station has a downside of problems with balancing and in this case was supported by flipflop logic.	^Spike^	Download PSG #189
11.01.11		Reverser Exit	The exit of this station is particularly interesting due to saving space by reversers.	thgergo	Download PSG #190
11.01.11		'2way eol	Trains simply pass around 2ways, however in a nice shape. If they do not find a free platform, they just loop into another line.	Intexon,V453000	Download PSG #195
11.01.11		'Two-way station with loop entrance	A bidirectional station where trains pass around waiting bays until they find one. And if they don't find one on the line they came from, they will try another line.	V453000	Download PSG #196
11.01.11		Reverser Entrance	This station uses reversers in station entrance. Note the need of PF trap to make trains "know" the path to station.	V453000	Download PSG #197
11.01.11		2 in 1 out Terminus	This station is a bit different due to using 3-tile X while 2 tracks go in (from each incoming track one) and one track goes out. A nice and easy way how to simplify balancing a terminus station with 2 lines.	V453000	Download PSG #197
11.01.11		Balanced station	This station has a few interesting points. Aside from the fact that it is huge, it balances all 4 lines into double "X"s which forces it to also use a lot of bridges atop of tunnels..	V453000	Download PSG #200
11.01.11		X-less Terminus	One of the terminus stations which lacks the "X" many people fear.	V453000	Download PSG #204
11.01.11		Looping station	This station is basically a normal 2way eol ro-ro but with the difference that trains which fail to find a platform try again on a different line which lets us use less platforms per line.	V453000	Download PSG #206
10.08.11		Balanced Station	One of the typical balanced stations with various exit techniques.	XeryusTC	Download PSG #210
10.08.11		2 platform rows	The main point of this station is to have many platforms. Therefore very fitting to use in maglev games as seen in the picture.	V453000, MrD2DG	Download PSG #211
19.11.11		Unbalanced two-way drop	This station is focussed on high throughput. By forcing trains in to the nearest platforms no pre-signals are needed. In this case penalties by road crossings are used in combination with two-way signals.	Xotic750, V453000	Download PSG #219
12.1.12		Semi-balanced drop	Sometimes it is just enough to make two 2 line entrance than a full balancing of 4 lines. Also note small signal gaps for high throughput.	V453000	Download PSG #223

Pickup Stations (what is that?)
Date	Screenshot	Specification	Description	Creator	additional
03.12.2009		Fail-safe	This station uses the same logic as fail-safe joiners do. Making combo multiple combo signals leading to 1 signal block not break. As a result, it looks .. well ... this way. ;D	V453000	Download PSG #193
03.12.2009		Overflow	An overflow with side detection of waiting bays and most notably with an escape route for lost trains. (when a lost train gets to the overflow, it would not see a path out through the terminus station and would stay stuck in the overflow forever, eventually would get hungry and die)	V453000	Download PSG #197
03.12.2009		Overflow	Overflow based on detecting platforms. Also featuring an escape route for lost trains.	V453000	Download PSG #197
03.12.2009		Overflow	A pickup station with quite an advanced overflow. NO, it is not presignal bypass! This combo signal arrays always checks if there is a train going to a platform and if the eventual platform is free. If there is a train, it is possible that this train would go to any other platform down the line and the overflow is not released. If there is no train but the waiting bay is full, the combo signals move onto checking the next waiting bay.	V453000	Download PSG #204
03.12.2009		Balanced station	A standard powerful balanced station.	XeryusTC	Download PSG #210
03.12.2009		Overflow	A bit special overflow on a balanced station. Using block pre-signals to give some priority to the incoming trains which have PBS.	V453000	Download PSG #219

Combined Stations (what is that?)
Date	Screenshot	Specification	Description	Creator	additional
11.01.11		Drop and pickup station	Here goes a typical Mark station with X-less terminus and a _ton_ of eyecandy.	Mark, Skasi	Download PSG #90
11.01.11		City station	Wonderfully looking city station.	Mark	Download PSG #105
11.01.11		Refit Station	A very simple refit station.	Combuster	Download PSG #141
11.01.11		PBS WTF	This pax terminal is very interesting by providing as few colliding paths as possible.	unknown	Download PSG #151
11.01.11		Tunnel bypass	This transfer station is special by the bypass for ML trains which is situated in tunnels under station.	Combuster	Download PSG #159
11.01.11		Double X-less Terminus	The one typical station for Mark. A terminus without X on the "main" side and the other station fitting into it. Awesome on the sight!	Mark	Download PSG #164
11.01.11		Refit Station	The first refit station with cargo return - on separate platforms.	V453000	Download PSG #186
11.01.11		Reverser Exit, tunnel under station	This station is trying to save space for towns by reversers in tunnels and tunneled exit from the station.	V453000	Download PSG #187
11.01.11		Space effectiveness	This was a double-station where trains transferted at one, loaded at the other. As the game had gotten many lines, the main challenge was to put the station within 64 tiles of station spread.	V453000	Download PSG #192
11.01.11		Refit Station	A refit station with cargo return on the same platforms long TL+1, using the [near end] and [far end] orders.	V453000	Download PSG #197
11.01.11		Transfer station	A terminus transfer station using a kind of X-less PBS entrance/exit..	V453000	Download PSG #200
11.01.11		Refit Station	A refit station with cargo return by TL+1 platforms and all platforms shared for all actions, be it drop, pickup or cargo return.	V453000	Download PSG #200
11.01.11		Pax terminal	A very special station using one ML underground and the station on the surface. Also note the extremely important message on it.	V453000,mfb,sturmi	Download PSG #201
11.01.11		Refit Station	A very advanced refit station being not only balanced but also featuring cargo return by TL+1 platforms and mainly stac-proof depots.	V453000	Download PSG #205
11.01.11		Merged pickup and drop	Every 2 platforms swap being drop/pickup. Quite an interesting way how to make a station.	V453000	Download PSG #211
11.01.11		Merged pickup and drop	First drop, then pickup. That is how this station works when trains pass around the 2way eol. However the most interesting thing on this station is the exit. Using PBS and 2way entry signals helps trains decide which line to choose without unnecessary waiting in waiting bays. Also note that each choice fork is made after just 3 platforms so the throughput of each fork is quite low.	V453000	Download PSG #216
20.12.2011		ICE station	Special design to make one side of the station drop passengers to the town and the other side load them to the next town. Entry and exit from two directions..	LoPo	Download PSG #221
26.12.2012		Multiple pickup and drop	Using one incoming line for all of the pickup platforms is not the sanest idea. However throwing drop platforms in the mix made it a bit easier as they made more space for the overflow logic for pickups. It still made for a bridge/tunnel madness.	V453000	Download PSG #222

Special Stations (what is that?)
Date	Screenshot	Specification	Description	Creator	additional
03.12.2009		SRNW Station	A nice SRNW station from the legendary psg 121. A so-called 3-bay SRNW station where dummy trains load, wait for other dummies to load, and then all dummies go to unload. The "waiting" part is usually solved by having 1TL waiting bay for those trains. However in this case it is smartly solved by using a NOT gate, effectively shortening the waiting bays to 1 tile.	Mark	Download PSG #121
03.12.2009		SRNW Station	A SRNW station using PBS to release trains.	Nickman	Download PSG #149
03.12.2009		SRNW Dummy	A NOT gated dummy SRNW station using platforms tightly together thanks to the mess on the exit.	V453000	Download PSG #172
03.12.2009		SRNW PBS Dummy	Not too complicated SRNW station as in system, but effective on space. Making many platforms just next to each other. It is wonderful to watch when all trains release together, but at the same time it is a bit painful to see the huge wave of trains flood the network. :) (psg180 had no issue with waves due to the flipflops fortunately)	V453000	Download PSG #180
03.12.2009		SRNW Dummy	A very simple SRNW station with just a few 3-bay dummies and full-TL waiting bays.	V453000	Download PSG #180
03.12.2009		SRNW Transfer	A transfer station fitting in SRNW network. After using some intense madness, it worked absolutely properly. Question is whether this amount of logic is worth it as the total throughput is not that stunning.	V453000	Download PSG #200
03.12.2009		SRNW Refit	A SRNW quadruple station. Uses refit orders between quarters, dummy trains with NOT gates, Mark's clock for overflow injection.	V453000	Download PSG #214
13.1.2011		SRNW Transfer	Station based on having 1 set of platforms used by both feeder and pickup trains. Each platform gets its own logic consisting of (only) 2 logic gates - NOT and a green->absolute red. Unfortunately requires huge amount of logic wires so making it small is an issue.	V453000	Download PSG #223
17.1.2011		SRNW Transfer	A transfer station which counts trains using (insane amount of) binary logic. Unfortunately some trains manage to run away without loading.	mfb	Download PSG #223
14.7.2012		SRNW Transfer	Yet another Self Regulating Transfer Station. The network trains are blocked by the reserved track by the feeder train - using PBS. Release then occurs when the feeder train reversed, and leaving the transfer station. With this mechanism, only a single logic "check" was needed to make this transfer working. Beside this, the station was also equipped with overflow depots for every cargo type.	LoPo	Download PSG #239
14.7.2012		SRNW Station	A SRNW station design with double Not-Gates. The first Not-Gate is to release the dummy trains - it will give a green signal when all dummy trains are loaded. This will then give a red signal to the second Not-Gate; which then releases the network trains.	LoPo	Download PSG #239
14.7.2012		SRNW Station	This new SRNW station design uses no Logic Gates, it uses some kind of cascade mechanism. The design is fully reliant on PBS. The first set of Path Signals make sure that the dummy trains block the network trains. The second set of Path Singals are needed to block the dummy trains, one for each other next to them, until all dummy trains are loaded. The last set of Path Signals is needed to block the dummy trains until they are all unloaded. When using this station, please make sure you really know how it works (it can break really easily), also it may occur that the last dummy loader is loaded at the same time as one of the others. This will also break the system, and thus meaning it needs expansion (the station will break if the production is to high for the dummy trains).	LoPo	Download PSG #239

City Networks

The city networks are a very interesting part of our networking. That is not only because there are so many ways how to build one but also because you often want it to look nice. In general the purpose of a city network is to catch as many passengers as possible and transfer them to the local passenger terminal.

City Networks (what is that?)
Date	Screenshot	Specification	Description	Creator	additional
15.04.08		Self-regulating	"A very nice self-regulating design where trains use only the [transfer] order.	Thijs	Download PSG #140
15.04.08		Direct full load order	"A very well extensible design working on the simple basis of full load orders which are affordable thanks to the 3 platform stations.	Mark	Download PSG #140
15.04.08		Direct full load order	"A layout which lacks any curves as it is just a system of straight tunnels going towards the central transfer station. Allowing for a lot of buildings in the town.	Mks	Download PSG #157
15.04.08		Waypoint loop	"Here trains first enter the row waypoint, then try to go to the exit of the row. While all of the ways how to get out are through one of the stations.Then drop the cargo and go to another row.	Spike	Download PSG #164
15.04.08		Direct conditional order	"A loop of stations where after visiting each station trains decide where to go. Unfortunately rail footprint dominates over buildings.	V453000	Download PSG #174
15.04.08		Serial Transfer	"Series of stations which transfer to the next station in the line, growing on TL(capacity) and eventually reaching the ICE.	V453000	Download PSG #174
15.04.08		Self-regulating	"Sbahn where trains have only the transfer order. The interesting addition here are the wooden bridges to make trains slow down in order to reduce the rate at which they visit individual stations. Resulting in more stations in the loop being used.	V453000	Download PSG #200
15.04.08		Direct full load order with walk	"A rather normal Sbahn with just the direct full load order. Enchanced/cheated by walking the sets of stations together to provide 1 station of 3 platforms instead of 3 stations of 1 platform to have a train always loading.	V453000	Download PSG #201
15.04.08		Conditional loop with waypoints	"A system based on trains going in a loop of N rows. Each row is ended with a waypoint where trains decide whether to continue towards the next row or to drop the cargo and then continue to the next row. This way all trains in the loop can share their orders.	V453000	Download PSG #201
15.04.08		Conditional Orders	"Sbahn based on trains going around stations until full.	XeryusTC	Download PSG #207
15.04.08		Layered city network	"This city network is based on having firstly the rail trains which transfer to the transrapid. And the transrapid finally transfers to the ICE. This is done to use the huge difference between transrapids and normal rail trains in capacity.	V453000	Download PSG #207

It is hard to describe logic shortly since it's very purpose is to do something extra. This section lists mechanisms and thingies that usually control trains somehow, and thus improve how our network works. Although there are for sure cases that are completely useless like train counters.

Logic and other constructions (what is that?)

13/07/2008		Train Length Sorter	Sorts trains by their length. In this example trains longer than 5 cars (or 2 tiles) will be sorted via the penalty, those of 5 cars or less through the non-penalty line. this is useful when trains of varying type use a station, and some platforms are shorter than others. It can also be used at junctions where there are two options of track, to move shorter trains onto a loop with tighter turns. Finally it may be used to seperate main line trains from local trains (assuming different train lengths). A local train may be forced onto a longer, slower loop to allow mainline trains to pass.

16/12/2008		Advanced Timer	An advanced timer which works with a certain cycle. Once the dummy train finishes the cycle, a train is released by the timer. However this has one crucial condition - if a train overflows, the whole cycle is cancelled and the counting starts again.	Mark	Download PSG #121
11.01.11		Train packing	The so called compressor. Waits until a few trains are ready to go and then releases them very close together, allowing trains further down the line join.	Mark	Download PSG #131
11.01.11		Flipflop	A typical flipflop splitting trains into 6 directions equally.	V453000	Download PSG #180
11.01.11		Counter	A mechanism which counts how many trains have passed a certain spot. Completely useless for the network.	HDIEagle	Download PSG #196
11.01.11		Counter/comparer	This array of stations had a special overflow which counted which station gets the least amount of trains and released trains to that. Therefore there are logic mechanisms which count how many trains have passed (based on Mark's clock) and a mechanism which says which station had gotten X trains as the last one.

11.01.11		Long train abuse	This mechanism is meant to pack looong trains in just 3x3. It is very slow due to the effective more than 1xTL signal gap.	V453000	Download PSG #203
11.01.11		Flipflop without memory (SR-NOR latch)	A very interesting way how to make a flipflop without memories, using the NOT gates swap their states. Unfortunately (probably) only usable for 1:1 split.	mfb	Download PSG #224
16.10.12		Pathfinder-based Perfect N-way split	A split from 1 to N (here 7) tracks. Fairly easy to build, with full throughput and does not seem to break.	V453000	Download PSG #245
2019-07-20		Logic-based Perfect N-way split	A split from 1 to N (here 3) tracks. Fail-safe.	Hazzard
2019-08-11		Base-1 (tally) counter	Train counter using memories as counting tally marks. Used for clock-synchronized SRNW. Allows N (6) trains per clock cycle. In this screenshot the input/output is in the top right with a testing dummy train.	Hazzard	Download PSG #334
