I really can't get mission 6 to work.
I've read the tips here. I have 4 class 103 trains, they are all on a single track, the track is almost entirely 300 km/h. The trains aren't doing too bad, but I can't get anywhere past ~350 passengers per year.
I think my problem is with the buses. Right now I'm not really sure what I'm doing, and just set up bus stops in every corner of the city, straight to the station. Resulting in 6 or 7 lines per city, each with a single bus, a lot of trouble, and not nearly profitable. Do I need to set them up in particular areas or something?
