TRAINZ is a railway simulation program for PC.
A number of different versions have been published over the years, the latest being Trainz 2010. Each successive version has required a PC with a higher specification, and full details can be found by visiting the web site of the publisher, Auran.
In addition to the built-in content which is included with each version to enable fully scenic routes to be built and operated, many enthusiasts contribute their own custom content to the Trainz Download Station. My custom content is grouped under the name ‘Dukes Denver Designs’. Dukes Denver is the name I used for a number of N-gauge layouts over the past 34 years.
