The script disables the standard train traffic algorithm and activates a new one. Thanks to this, now: -movement is carried out on both paths, and on each path only in one direction - trains appear much more often, they don't appear suddenly and near the player - trains are marked on the map with markers -there is an opportunity to ride a 19-car train If you set (for example, using the SATL 3 program) for some type of train (except 7,13,15) the number of cars is 15, then when generating a train of this type, 4 more cars will be attached to it, the same model as the 15th. The mod also includes files for train routes (tracks), which are more accurate than the standard ones.
