I found this today doing my usual train simulator search. Its an online simulator of the enoshima line of Japans Odakyu Railroad. Its actually not that bad once you get a hang of the controls. Its not an actual simulator but seems to be a video of which speeds up when you do. A good way to kill a few minutes for the over average railfan. Try it out and leave some feedback
