I am speechless. My only words is woah. I think this game is very good. The missions, the things you can do, the graphics. These are all small things. So, here are my suggestions!
Level Making! Levels are so good, but the ability to make our own levels would make it even better! We could make and run our own railway, and maybe new objects to top it all off!
More Trains! The selection of locomotives is already nice, but maybe some new locomotives and maybe the ability to modify them, perhaps the more missions you complete you unlock modifications for your locomotives. Some examples are faster engines, better braking systems, more fuel, ability to run on non-electric lines, etc
More realistic derailments! The derailments are already nice, but a tiny collision wouldn't make a train blow up. But off the point, make it to where there is a speed limit on certain lines, and above all, if we go too fast on a curve, we will lean over and derail!
There are all my ideas. But it's your game! You got this man!
