#OPENTTD PATH SIGNALS HOW TO#

When this happens, it should now be considered a bug in TTDPatch, please report any situations in which a train is unable to reverse. Otherwise, the "reverse" function will be disabled, the train will be stopped and both open its vehicle window as well as generate a news message.

When trying to reverse direction in a PBS block, the train will only do so if it can successfully reserve a path out of the signal block.

If the train cannot find a useful path at all, it will take any path if it is currently at a green signal.

A train will look for paths that end at a red one-way signal.

A train will not look for paths that end at a red two-way signal.

The train can pass a signal if it finds a route past the signal leading out of the signal block or to its destination.

Whether these signals are red or green does not matter for whether the train can pass them, except that if the train can't find a route to its destination, it will wait at a red signal, but not a green one.

A train will never find a path that crosses more than 7 junction tiles.

The paths through the junction must be shorter than 64 tiles and cross 7 or fewer junction tiles.

Track with signals, or track on or below bridges does not count as regular track, whereas road crossings, stations, bridge heads and tunnels do. Every PBS signal must have at least one regular track piece between it and the next signal, or else the train will not be able to pass the signal.

Do not put another signal immediately after a PBS signal.

Here are the requirements needed for making PBS work correctly:

#OPENTTD PATH SIGNALS HOW TO#

Uwe Domaratius has written a very nice tutorial that explains how to use path-based signalling (among many other things). To make path-based signalling (PBS) work correctly, you have to obey a few rules in your junction design. This is the case even when automatic PBS blocks are disabled. If one signal is using path-based signalling, then all signals leading into that block will be converted to path-based signalling.

You can disable this by enabling the "autoconvertpresig" setting off the switch, in which case you have to set one signal in each block manually by cycling the states with Ctrl. These reserved paths are then shown somewhat darker, and other trains will not reserve paths that interfere with them.īy default, all signal blocks which have at least one pre-signal, exit signal or combo signal leading into them will be converted to path-based signalling as soon as the block becomes clear for the first time. The non-exclusive use of signal blocks is achieved by the trains "reserving" a path through the signal block. Show reserved track pieces on non-junction tiles tooĭon't hold trains at an unsafe PBS signalĭon't stop trains that can't reverse safely This is a bit switch, with the following choices:Ĭonvert pre, exit and combo signals into PBS signalsĭon't convert junctions with manually set signals into PBS This greatly enhances the entrances and exits of stations as well as junctions. Path based signalling is a feature that allows several trains in a signal block as long as their paths do not interfere. You will need the base graphics from the top of the second table on this page in order to have TTD properly display the PBS signals. If another train's desired path would cross the path of that train, it waits at the signal to reserve a path before entering the junction. As a train approaches a path-based junction, it will reserve a path through it (the rails it has reserved will show up darkened). Path-based signalling (PBS) allows multiple trains to share a junction, as long as their paths do not cross. Please read this entire page before trying to use it. Note: This feature is somewhat dangerous, it may lead to train crashes if not used correctly (sometimes even if used correctly due to bugs in the code).
