Worth a look, but no Railroad Tycoon
Second, i don't think the zoom in/ zoom out feature works well enough. I'd like to be able to zoom out further to see a bigger picture, have resources identified with a label (like previous versions), and play the game with LOWER resolution. Not all of us have 20/20 vision, and personally, I prefer to play a strategy type game such as this at 600 x 800 so I can see what's going on.
I'd also like to see a greater number of engines, for example instead of just the "F Series", use the F-2 through F-9's as upgrades. More detail about the original loco's, who built them, what major RR's used them, and so on would be great.
