Sideline Hub
From #openttdcoop wiki
(Redirected from SLH)
A sideline hub (SLH) is the most common type of hub used in #openttdcoop games. It's purpose is to connect a sideline to a mainline. We usually build sideline hubs using prioritized mergers to avoid slowing down mainline traffic.
Examples of sideline hubs can be found in the Junctionary.
