Logic and Other
	Back to junctionary

It is hard to describe logic shortly since it's very purpose is to do something extra. In this section can be found mechanisms and thingies that usually control trains somehow, and thus improve how our network works. Although there are for sure even 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
