I used but it stops for a second in the path corner.. and GO to the next and again it stops for a while... even i gave all path corners wait - 0 and speed spawnflag to 1000 (while train speed is 500) it still stops. Probably because in gtkradiant it is written like this: TURN_TRAIN func_train moving on this path will turn to face the next path_corner within 2 seconds
