I have a 5.5% grade on my railway that the Bachmann BH's can get up with tender and 3 cars, but they struggle just like a real engine would. in another area there is a 2.5% run that they have no proble with pulling up to 8 cars and the tender, I have not had a stripped or split gear yet, but expect it will happen sometime./DesktopModules/NTForums/themes/mls/emoticons/blush.gif If you can manage it keep the grades under 3%.
