Needs Lots More Work!

This app is a bit pathetic. When I first downloaded it, it wouldn’t create anything but a 10 x 10 layout. Then I found an update which solved that. However, there appears to be no way to operate turnouts (track switches). I haven’t been able to elevate track. I can’t remove trains without also removing track! This app needs tons of work before it will be enjoyable to use!

This game is the worst game never play it

I hate this game sooooooooooooo much I can’t even make a mineral that has six cares or more bc what will is when I revers when the train hit the train cars it will stop and the back part of the monorail will move. I also have this problem where a train will keep stoping in the middle of the railroad crossing even though I got deleted it and the station it still keep on stoping. This is why I hate this game.
