The Northeast Corridor route is missing a fair number of details along it, many of which were added back in by third party developers.
Rail Simulator was also developed by Kuju, but starting with its successor Railworks it's developed by a new company that later evolved into the simulator-focused Dovetail Games, which also re-released Microsoft Flight Simulator X on Steam. The game has a commercial Spiritual Successor of some sort, sporting the different names Rail Simulator / Rail Works / Train Simulator 20XX. There was a Microsoft Train Simulator 2 which got canceled twice, in 2004 and in 2009.
