You may never have heard of Trainz, but if you're into train simulators it is the best, perhaps the only, game for you and now the million-copies-sold game is getting multiplayer.

Starting this January Australian-developed Trainz Simulator 2010 is going into open beta with multiplayer, with plans to have the new feature go live by the second quarter of 2011.

The developers says that Trainz Multiplayer will let you interact with your friends and other Trainz players from all over the world. "Collaborate, compete and work as part of a well oiled machine running a huge rail system. It will be bigger than you ever imagined...," according to the press release.

To get access to the game's open multiplayer beta you must own a copy of Trainz 2010 and register your CD Key on Planet Auran by Jan. 10.

This is one of those games I've known about for years, but have never tried. How is it?
