Owners of the legacy TestTrak route will soon receive an update patch through their Steam Client. TestTrak was an early piece of DLC developed by Dovetail Games, and was included with all previous versions of Railworks and Train Simulator up to Train Simulator 2013. This patch includes some changes to the location of files of TestTrak and disconnected references to other asset packs sold on Steam. This patch will not affect scenarios for the route and scenarios supplied with DLC from Steam will continue to install on TestTrak as before, without interruption to service.
