With this mod, FREIGHT trains are sometimes very long (up to 140 wagons: 1.5+ miles (2.5+ Km)). Some are mixed freight; some are unit.
All trains have only one loco though because I haven't yet figured out how to add more (I'm working on it).

Note: Except Phoenix, which has only a light locomotive.

CAUTION: When very long trains appear (50+), hardware resources can be taxed (fps drops significantly). If that happens, check your game's root config.cfg; set "uset g_lod_factor_traffic "1.0"". If it still stutters badly, use the sister mod:
