Am running service 5A62 which is to run a 52 from Padd station up to OOC. Running along the line is fine until you hit the 1:98 slope heading down into OOC after crossing the bridge. No brake application and no throttle application and the loco slows down as though it's going up a hill instead of down one. Something's not right if that is happening no matter which cab of the loco it sets you in.
Are you light engine? If not your rake of coaches could be on the other side of the gradient holding you back.
This is a very strange phenomenon for that part of the route and has been reported before. It’s like there is a train magnet pulling you back up the hill. If you stop the train and release the brakes in the right area you will actually roll uphill. It is one of the oddest bugs in TSW.
