of the brand and supporting users and third-party developers with add-on projects. RSDL produced two patches to the core simulator (Upgrade Mk1 and Mk2), developed and released add-ons, helped the release of third-party products, and visited exhibitions to promote the simulation and provide support for users via several community websites. In April 2009, a take over of RSDL was announced, with the development switching to a new version of the software called RailWorks which would be released on Steam. This change heralded a break from EA being the publisher in Europe and rights over the source code for Rail Simulator being transferred to single ownership by RailSimulator.com Ltd. Successor RailWorks (since renamed to Train Simulator Classic) is the official successor to Rail Simulator, announced by Tim Gatland on 26 March 2009 on the official Rail Simulator website. The game was released on Steam on 12 June 2009 and in stores on 3 July 2009 in DVD-ROM format. RailWorks is an upgrade to Rail Simulator, containing new rolling stock, tools that had to be separately downloaded, significant graphical advancements such as modification of the existing content, bug fixes, backwards compatibility and the ability to trade elements from the virtual world with other users online. RailWorks is a universal platform containing all content from the original European release and North American release. RailWorks also makes use of Valve's Steam platform to simplify the processes of support and upgrading the product.
