NGL this was the third time I tried to start the series, the other 2 times I had recording issues, I did place the depot where there was a depot irl the other two times but this time I couldn't really be bothered idk why. Maybe because it's advantageous to have a depot where your routes start but I wanted my routes to start in Central London, where there aren't any depots irl.
Stopping at Battersea Park station would have been sufficient for your public service route. Any extra revenue gained from all those extra stops goes to the public service company, so wasted.
