A few issues/bugs that I have spotted while playing the first time on Tees Valley Line. First, the map achievement boards seem to reflect a bit on the back at quite a few stations including Dinsdale, Thornaby and Redcar Central. There seems to be a passenger issue at Longbeck where quite a few seem to be merged together in a area that blocks other passengers making it difficult to pass. The stopping point at Darlington Platform 1 is at the very end of the platform. I find that strange as usually trains would stop at about the middle of the platform where the majority of the passengers are standing. That's where I was stood waiting for the train to arrive in game and was surprised it travelled all the way to the end of the platform. The level crossing at Allens West looks to be sunk a bit below ground level on both sides. In the menu for the Class 37 services, the description for services 6S11 and 6S17 say that the service go as far as Eaglescliffe where actually it goes all the way to Darlington. There are the few issues/bugs that I found on my first run of the route. Will add anymore that I find. Overall I think its a pretty decent route and Dovetail have done a good job with it.
