Info

Rail.obj is a file containing key locations of train movement. It stores location on world map, and the train automatically rotates, gives power and calculates needed info (like cargo rotation and etc.) This file cannot be compressed. Doing so makes the game don't recognize the file.

File scheme

The file is built the similiar way as World map WMX.obj. The engine is loading animation for specific train every 0x800 bytes (2048). Always. Animation cannot be larger than 2048, and if is smaller than 2048 bytes, then what's left is filled with 00. One animation frame is 16 bytes.
