Apologies if this has already been reported; but on some GWE services the throttle on the 166 does not engage. It moves but there is no acceleration. Thanks
One is 2P35 Reading to London, another is 2R27 out of Paddington, there was one other out of Paddington that I can't remember.
No mods! Fresh installation of TSW4-compatible GWE Route. Verifying files now, this takes about 90 minutes. Thanks for responses!
