Reality: 11 bus-lines to/from the railway station, but then take a look at the bus stop. I'm sure its a bus port with min 4 lots. Lueneburg (Germany) with 72.000 citizen: Bus port with 14 lots! Winsen (35.000) bus port 4 lots, railway station stop: 4 lots. And of cause these are seperate places where buses don't have to stop on the street. (Example:

And the problem at the south railway station is even the same with 3 or 5 routes. You need 20 and more buses/trams. And you can't build turning cycles for buses. Every line, every bus have to take the same streets and have to wait for stoping themself or for other lines, cause you can't passing other buses. So you have the same traffic jams and a catastrophe if only one bus have a breakdown.
Fact: Even if there are less citizens in the towns, there are still 40 people at the station and for these passangers you still need 4 trams to transport them. And of course you can't build a metro-station every 100 meters.
