Dovetail Games

Dovetail Games (DTG), a trading name of RailSimulator.com Ltd (RSC), is a British simulation video game developer and publisher. It was formed in 2008 by Paul Jackson (formerly VP at Electronic Arts and Director General of ELSPA, now UKIE), Tim Gatland and Charlie McMicking. It originally produced the RailWorks franchise, now called Train Simulator.

Developed for the PC, Train Simulator is available both as a boxed product from video game retailers and as a download via Valve's Steam platform.

RailWorks' predecessor, Rail Simulator, was developed by Kuju Entertainment, the same company that developed Microsoft Train Simulator with Microsoft. With the release of Rail Simulator in October 2007, Kuju Entertainment finished development and disbanded the development team, turning its attention to the next project.

Knowing the potential of their proprietary game engine, and with backing from Fund4Games (Tim Gatland and Charlie McMicking), a new company was set up called Rail Simulator Developments Ltd (RSDL) from some of the core members of the initial development team with the specific aim of fulfilling continued development of the brand and supporting users and third-party developers with add-on projects. RSDL produced two patches to the core simulator, 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, the formation of a new company was announced. Jackson, Gatland and McMicking went on to set up RailSimulator.com Ltd (RSC), employing many of the original creative team, along with Steve Bainbridge (previously of Electronic Arts and GAME stores) and Duncan Best (previously British Academy Video Games Awards, ELSPA and Director of the London Games Festival).
