I use: 2% slope for normal loco's 4% slope for locos with traction tires 6% slope for geared loco's, climax, heisler, etc. with traction tires. Go slowly, keep your rise gentile so you don't break traction and experiment with your locomotive to see what yours will climb. then try it with your cars attached see if it will climb or just break traction. Happy Rails. dave #Post#: 1859-------------------------------------------------- Re: Maximum slope By: Flynhi Date: January 7, 2018, 3:00 pm --------------------------------------------------------- Thanks Fave So how many linear feet will it take to use a Lionel graduated trestle set- just up and down with no horizontal section at the highest point? Will #Post#: 1863-------------------------------------------------- Re: Maximum slope By: djacobsen Date: January 11, 2018, 8:02 am --------------------------------------------------------- Flynhi not certain of the rise on a Lionel tressel set, works on a basic cross over layout so my guess would be around 4 to 6 linear feet to get the rise to horizontal. I have Marx tressel sets & imagine they are close to Lionels' in rise. works on a 4 x 8 layout/crossover. happy rails.. *****************************************************
