RailWorks

IGN gave RailWorks a seven out of ten, or "good", stating that the game "doesn't bring a lot of new stuff to the genre" and graphically "lacks the high-end flair of today's top-level titles". RailWorks 2 won the award for Simulation of the Year 2010 by readers of Game Industry News (GiN).

Steam is used to deliver additional routes and locomotives in the form of paid downloadable content. The core game has received several updates since release, with the game's title adjusted to coincide with major releases. In 2010, RailWorks became RailWorks 2: Train Simulator and was then followed by RailWorks 3: Train Simulator 2012. The RailWorks branding was dropped with the next major release, titled simply Train Simulator 2013, and this naming convention would continue with yearly releases until Train Simulator 2022. The current version, Train Simulator Classic 2024, was released on 21 May 2024.

The first major update to RailWorks was RailWorks 2: Train Simulator, released on Steam on 18 October 2010 under the name RailWorks 2. Retail versions were released later that year.
