Model Trains have had many innovations over the years such as trains that smoke to rail sounds and now we have whistle smoke and disappearing coal loads.
So what do you think will be next?
Passengers talking or walking inside car, trains that ask you for permission to proceed, programmable stations so you can make your own stops, trains that stop based on signals given, diesels that smell like diesel (lol),bosses that yell at you when your not on time.
