I just discovered this game, and find it strangely compelling. Naturally I had to try a section near home, and tried dispatching the Canadian Pacific between Minneapolis and Portage on a Sunday. Like the OP (eight years ago), I now have a much better appreciation for how difficult dispatching is. Try as I might, I still ended up putting the Empire Builder on a siding when it met an intermodal too long for the siding, and it ended up late into La Crosse. The shame!
I would try it, but as an engineer, I already KNOW I'm over qualified to be a dispatcher!
