Oh, well I just typed the wrong thing.
It works exactly the same.
OnPass - Stop - Whoop de doo
"[i]OnPass[/i]"
"[i]train name[/i]"
"[i]Stop[/i]" (Notice that it might not be called stop, but the name of the input should be quite obvious)
The train can easily be reactivated again using the input StartForward (or StartBackwards depending on direction)go into source SDK's properties, and find the Launch Options button.
When prompted, type "-engine ep1" and hit ok. Your SDK will now be configured to map for pre-orange box games, providing you own them, of course.
all i have to do is manually run the game and the mapThat however, does not make any sense.
