Got this cheaply from a bundle and was not at first impressed at all. after awhile the simulation part starts to show and you go deeper and it starts to look much better.
This particular game is however basicaly 'trainz lite' due to non-functional save game. If you can keep the PC on at long times then no problem using this game. This game managed to hook me pretty well quite quickly even without save: there just is something in it trying to manage a huge freight train, or trying to keep up with timetables when you move passengers. Steam or electic trains for choice, Simple toy train DCC controls or realistic CAB control modes spice up the experience well.
Things go sour if you really must have save and dont have any other trainz game that saves sessions properly like Trainz 12.
I'll be playing that game now. Working save. Better content and proper tutorials that this game lacks.
