Following on from my post in Developer Fails about derailing between Westbury and Bathampton, when only exceeding line speed by about 2 MPH thought I would try a different consist. This time I brought in the ELR Class 37/4 and rake of Mark One coaches however on starting up the activity I only just managed to get beyond Hawkeridge Jn before the sim locked up with graphical distortion. Tried rolling back my Nvidia drivers as I know there have been issues with the latest version in some other games (Deus EX HR for one) but same problem occurred.
If anyone else has Bristol to Cardiff V6 and the ELR pack wonder if you could run a similar activity (Westbury towards Bristol) and see what happens. At this stage I can't tell whether it's route or train related or maybe just MSTS is finally giving up the ghost on me (big box of goodies looming for Ebay in that case).
