I really prefer to use a switch list. Many model railroaders may not be familiar with your layout location, town names or the industries along the way.

A switch list starts off with the consist of car with names and numbers. It then goes to tell the operator what car(s) get dropped off at each industrial siding. Then and lastly what cars the train and it’s engineer will have after all the switching is accomplished.

One thing to remember with switching or shunting of cars PULL BEFORE YOU PUT. Simply put means,== go get the car(s) in the industrial siding(s) before the operator places a new/ different car there. I find this system is better even for experienced railroaders and modelers. This is my story and I am sticking to it AS a PS ==
I live in the Raleigh, NC area USA of course!!!
