![]() Basicly the same as a toy train going round a loop on a table. this means that every part of the track will only ever be traversed in a single direction. The simplest solution is to make a full loop with double tracks. In order to allow travel in both directions, both sides of your track need to be signaled so the train can read the signals from either direction. ![]() Signals indicate the drive direction of a train but only unidirectional! This means if you place a track horizontally and a single signal benath it, the trains on that track will ONLY EVER be able to go from left to right. This is the most likely cause for the issue as it appears that you have made a train track that can be traversed in 2 directions(As it is a singular looped track). One of your stations is rotated the wrong way. There is a break in the rail line somewhere that you missed, maybe it got biter attacked? Are you able to reach the station by driving manually? This usually means one or all of the following problems are present: If, however, you are trying to run multiple trains, refer to my "this may sound stupid" comment. This turns the train stops into their own blocks, and has everything else one giant block. Honestly though, if you're only running one train, you only need 4 Rail Signals : one right after each of the two Train Stops, and one right behind the train when it is parked at that Train Stop. Here, for the two-way track, the use of chain signals is to prevent another train from entering the two way portion. If the train's desired path has a Red Rail signal, then the train must wait all the way at the Chain signal it encountered, even if other paths are Green. And, if the train's desired path has a Green Rail signal, the train can go through. They look ahead on all possible paths until they reach Rail signals on all of them. However, they also look ahead to the following signal(s). Green, its clear red, its not clear and all trains coming need to stop at it until the block is clear.Ĭhain signals are similar. Rail signals tell trains "The block just after me is clear/not clear". Only *one* train can be in a block at any one time. You can get a colored indication of the different blocks when holding a signal near the rail. It also, for future-proofing, allows for more trains on it at once.Ĭhain and Rail signals break the track up into 'blocks'. One way, looped track is far easier to get going than two-way track. Green if all target signals are green, Red if all target signals are red and there is also the special Blue case, which means that out of multiple target signals, some are red and some are green, meaning some routes are open and some arent. It then takes on the same state as the signals ahead. If not, it will be green.Ī Chain Signal does not detect trains, but instead looks at all signals that limit the block ahead, including crossovers. If the block us occupied, it will be red. If though, you have a track that trains can drive over in both directions, in order for them to be able to path, the signals need to be on both sides of the track equally.Īs for how signals work themselves its rather easy.Ī Train Signal looks ahead of itself for any trains present in the block of track ahead. If you have a track that only ever gets driven over in one direction, then you will be fine with a single side being signaled. Meaning, that a train coming from the direction the signal does NOT point to, cant read that signal. So like I said earlier, a singular track MUST always have signals on both sides of the track equally, as train signals are Unidirectional.
