I've been into HO railroadig for 30 years always operated on club layouts. I moved and I am going to build a layout at home.I want to put in a grade or two and cannot find any information on grades.I understand 4% is a number that is used. So how many inches of yrack do I need to do a four inch rise?
Thanks for any help you can give.
