This tutorial assumes you have already set up your model railroad.
"Railing" means putting a car on the rails. The gray ramp in the photo is a plastic railer; if your train set didn't come with a railer you can buy one separately. The railer has notches that fit over the rails so that rolling a locomotive or car down the railer will place it on the rails properly. Without a railer you will have to rail your locomotive and cars by hand.
