Pour info, Chris Sawyer a mis a disposition des joueurs une astuce permettant de conduire vous-même un train sur vos voies:

To access train driving mode, bring up the train window for one of your trains,
make sure the train is fully stopped (red flag icon), and that the train window is the topmost window on the display.
Then hold down the "INS" (insert) key on the keyboard while typing DRIVER then release the "INS" key.
Now if you access the stop/go menu on the train´s flag icon you should find a new third option in the menu called "Manual".
