Just found a rather minor bug that's quite odd. On the weekend I was playing one of my scenarios on the transpennine line and I had to do something else so I saved it and just came back to it. I saved it at a station with passengers loading, when I then pull away I have no speedo (train or hud) until I stop at the next station and it rights itself.
The save game currently has a lot of issues ever since it came out with tsw. So there's a chance loading a save will cause problems. Dtg only recently started looking at it. A fix was released already and dtg are continuing to work on it
