What aspects of railroading have been simulated in VR?
The earliest desktop computer simulations were limited by the graphics capabilities of the computers, thus the first simulations involved such things as recreating the job of a train dispatcher (e.g., Train Dispatcher). Then came the strategy games, simulating the empire builder (e.g., Railroad Tycoon). JBSS Bahn was the first to simulate entire transit systems and railway divisions, using 2-dimensional graphics and displaying trains, tracks, and scenery in isometric views.   The advent of full 3-dimensional modeling capabilities on the personal computer led to Microsoft Train Simulator (MSTS) and Auran Trainz, both of which let you view the train from all angles, inside and out, and to drive the train from either position. Another form of 3-D sim is represented by Boso View Express (BVE), which is cab-view only, and focuses on the driving challenge of meeting a schedule while obeying all the rules.   Large computers have been used for a much longer time to simulate the driving
