Very Pretty looking game, which for Sim lovers COULD be excellent. However is completely ruined by lack of tutorial or instructions, poorly designed aspects (eg markers yards away from where you are actually meant to be).
Unless you are already an expert in driving trains (in which case, unlikely you would be playing a sim doing what you do IRL) BE prepared to spend HOURS of frustrating time trying to randomly find and try various random levers and buttons just to get a train moving (or similar time spent trawling info sites and videos).
Of course, just as you overcome 1 hurdle there are three more that simply make the game so frustrating it is pointless trying to play.
One thing besides the purdy graphics they did get right. Taking ALL the issues and glitches and bugs and annoyances from TSW and making sure they are still present and even worse in TSW 2.
Dont Bother with it unless its totally free then perhaps if you want to kill a few pointless hours give it a shot.
