I like “Train Sim” on an Apple iPhone 11 Pro. The best thing is that it is free at the Apple App Store and free always gets my attention.
You the engineer starts at the roundhouse by picking your locomotive and climate.
“Train Sim”, starts with setting up your day on the rails.
You can control the locomotive from inside the cab and pull the whistle cord.
You can also change out the locomotive & share your game on Facebook, Twitter and other platforms.
