A post on 'The Little Wheel Goes in Back' blog, written by one of the developers, on Augsuggested the working title was 'Train Simulator 2'. The game would have used the Microsoft Flight Simulator X graphics engine and it was planned to be compatible with both Windows Vista and Windows XP.
This time the game was being made in-house by Aces Game Studio ( Microsoft Game Studios) known for its long line of Microsoft Flight Simulators, as a part of the ' Games for Windows' initiative. On January 19, 2007, Microsoft announced the relaunch of the Microsoft Train Simulator project.
