Just installed class 66 add on for RS and noticed when I apply the brake then release them the train picks up speed. So if I release the break say doing 20 mph the train will then speed up to 30mph and it does this no I am not applying any power. Its very annoying because I was pulling up to a signal and released the break and the train shot through the signal

. I also had this problem with a 47 also but since I reinstalled RS it just does it with a 66.
P.S Merry Xmas to everyone at Uktrainsim
