You can always change this number yourself, this model is aiming for some realism.

I really like to use this bus now that the feature to choose which bus you want on a line is vanilla. However, the vanilla bus has 30 cap. The Citaro G now has almost as much capacity as the metro (180). 160 is really too much, there is almost no point using other modes of transport.

160 is based on the real number of 159, 60 would be more realistic an 10.6m bus.

160 is too much imo. 60 is better.
