You have total control of the trains, first selecting from the wide variety of rolling stock to build trains up to 100 cars long. You can arrange custom trains by coupling and uncoupling cars in any order you choose. You can use or edit the predefined pick-up and delivery schedules and choose to control up to four trains on a layout. For the die-hard railroad enthusiast who enjoys a real challenge, import your own custom layouts from 3D Railroad Concept & Design, including all 3D objects, grades and elevations.
