Please, please, please - one of the things I personally hated most about Locomotion were the ridiculous handling of passengers. It is the most unrealistic and boring thing if passengers enter the vehicle and leave it at the next station. Plus they don't care which train comes, they take the first one. That is just insanely stupid. I would wish passengers to have destinations and to be just a little bit smart, maybe comparable to Traffic Giant. That was the best solution between easiness and non-stupidity!
Then while you're waiting for this game to be released, play OpenTTD with the Cargodist patch, which is making passengers pick destinations according to the reachable destinations (ie. you have to make the network first), or the YACD patch which works differently (I'm probably wrong since I don't play it) - passengers pick their destinations before the network is made, so passengers have fixed destination and doesn't change by network.
