Hi Anders !
To change the speed of the locomotive you have to edit the .con file manually. This might could get a become a little difficult.
ops:
But it's not recommend to do so. Changing speed restrictions and erase ATC is not very helpful if you want play an activity. Sometimes you are not able to play.
If you plan to create an activity for all the others you have to left the .con file as it is cause all others won't be able to play your activity else. :cry:
If you just want to take a look around at the route use the Route-Editor instead. :top:
But I think you should give good created routes, trains objects and activities a chance and join or explore them by using original speed.
