Version 1.2 also includes a few new activities for the new train equipment. Later, some more stock was added, including: Drivable SD40-2 with BNSF Heritage I paint, a Class 40 British Locomotive, New British Passenger Cars, A few new US freight cars, and A US caboose with a special "caboose view". However, this generally does not detract from the experience. There are also issues with the signalling.

The original version contained many bugs, for example the "front coupling bug" and the "white void bug". You can also, however, create activities for any route, make custom cabviews or edit default ones, and the 4th program allows you to create a route of your own.

Included with Train Simulator is the Editors & Tools program, which mainly allows you to build railroads, or "routes", as it is called in the simulation. New routes, trains, sounds, cabviews, and other MSTS accessories are available now on the internet, many for no charge. The quality of these is very much greater than the originals. However, similarly to Flight Simulators, people started building and distributing their own models through websites. The original models were criticised for being inaccurate.
