One of the most annoying things about TSW is the lack of passengers on return journeys. I enjoy using the simulator to do shifts of driving the same train back and forth up the line, for example, from Euston to Watford Junction and back, but it is pretty frustrating to be entering empty platforms and driving empty trains, even on the first run. I have tried adjusting passenger density commands in the ini file but it seems to do nothing, just ghost trains and platforms after the first stop
Lately I have been noticing the same. Latest playthrough was on updated WSR. Start of the trip is full, lots of passengers waiting and movement. Next station it is about 50%. After that no passenger boarding or waiting or getting off. Platforms are deserted. Does not affect gameplay but takes away the realism feel.
