I have an extra tile on my list of trains called "Missing Name". It has 00/00 services completed and no liveries. This is on Steam and it appeared after all the TSW2 stuff installed.
Do you have the class 52? I bought this and for some reason I lost WSR. I wonder whether as the home route not here it’s not pulled over
There is a missing name train on HSC too (Xbox One build). On TSW2, this showed a picture of a freight wagon for some reason and it had 1 service.
I have noticed this also. It doesn't to be anything to do with the class 52 or WSR. They both came over Ok for me. I approached it by going to each route and looking at the timetabled locomotives but that all looks Ok. It only appears when you select by locomotive.
