I know the 86/4 bundled with WCML-N and the 86/2 with the Class 86 DLC both have acceleration issues, however I'm pretty certain these were fixed in the original issue of the 86 EP from AP.... I am upgrading an old scenario I made for WCML-N, and with the original AP 86 EP could easily be at line speed when passing Polmadie, and keep to it for pretty much the rest of the run, but with the latest update of the 86 EP I struggle to get the 86 to line speed before hitting the grade beyond Polmadie, and usually end up tripping the overcharge when still 10mph or so below line speed (when line speed gets up to 90 mph).... Something must've changed to negatively affect the acceleration here??
AP have overhauled the gradient physics. They say it's much closer to the real thing now. https://forums.dovetailgames.com/th...pdates-for-info-only.41703/page-3#post-932690
