![]() ![]() If these signals are on a particularly long piece of track, you can place one next to each merge/split, or even have more than two. The goal here is to ensure trains do not block more than what they need to. This is the same principe as for basic one-way merges and splits. Tycoon allows only bi-directional signals, which allow trains to pass in. Most of them were dealt with when we added signals to the middle intersection, but some are still left out. Transport Tycoon is a video game designed and programmed by Chris Sawyer, and published by. The last step is to make sure all branches have been divided, in order to improve efficiency. **At this point, the intersection is jam-free.** As long as trains aren’t getting backed up from down the line, no trains will be stuck blocking other trains. The signals leading into the intersection can be as close as they like. This ensures trains that enter the intersection will always be able to leave the intersection. But usually, you’ll need to delete and/or move the signals so there is more room. How much space you need depends on how long your trains are, so this one may be fine as-is if the trains using it are all short. Now we must make sure that after this block in all directions, there is enough space to fit an entire train before the next signal. All of the next signals will serve this part.Īll rails going into it should have a pre-signal on them.Īll rails coming out should have a normal signal. Now it is clear we have one *actual* intersection in the middle. ![]() We can fix that.įirst, identify which parts are only merges or splits, which is any part that has three branches. Right now it is inefficient and prone to jamming. This is the most important part of signalling since incorrect signals in intersections can easily cause jams, and since intersections are the most complex part of your rail system.įirst, you should start out with an intersection. A pre-signal and normal signal will function the same in this case, but if you later expand the rail system, it will need to be a pre-signal.īecause of the limitations of VT signals, there is no general way to have more than one train on a two-way branch at a time without risking head-to-head jams. The one exception is the last signal before a dead-end (such as a station). Any normal signals on the two-way track will allow trains to come head-to-head and get stuck. There is no need to have any other signals. This allows multipe trains to serve different stations on the two-way track system. The important part here is that each branch is a different block. This is slightly worse since a train has to pass two signals before another train can pass, but will still function perfectly fine. If you do not have room for signals in between, you can have them on the ends. All signals on two-way rails should be pre-signals, and the only useful place to put signals on two-way rails is at intersections. ![]()
