I’m pretty sure the rail/road crossing complaints are all going to be addressed to your liking – “Cars” are supposed to stop at the crossings, sound is intended to play from the crossing and trains should always sound their whistle at such a time.

As for the stations – I’m with you there. The number of times I’ve accidentally placed down a Passenger station at a factory is starting to grind my teeth a bit. ^^

I’m not sure exactly how many additional industries the devs have planned, but I hope it’s a lot. More car designs wouldn’t hurt either so that goods and lumber don’t share a wagon (as nifty as it is for my trains)
