Looking at the first emission of fumes from the top of this Class 40 (3:15 on the video), then the sounds a few seconds later, is this correct, or is the sound delay a scripting error? Compare to the AP 37, where the two are synchronised (at 1:30)
I'd say there's just something wrong with the video, because that's not what happens in game for me. Does yours actually do this in game?
Yes, will have another go to check, but not first time I’ve noticed it. The YT video quality is a bit ropey, but that is a result of my software rendering the original screen capture video. In a previous version of a 37 start up, the dashboard gauge needle just jumped in increments. Wasn’t like that in the original video:
I've never seen that here with either loco, sorry. Maybe wait to see if others can replicate the issue.
