Now, if the difficulty in this game gets so that you don't have millions in the bank, come 2010, then being able to automatically upgrade all your railways to monorail just won't be possible (unless the cost is small

So, my question is, can you currently create a monorail station that's part of a railway station, thus making the upgrade process a bit less painless? (I'm at work, and can't check)
I'm also thinking that, by the time you get 300mph maglev's, that the difficulty will need to be increased further. Huge coal trains sprinting the length of the map down perfectly flat straight railways make ridiculous (yet satisfying) amounts of money on each run.
