Other than freight on the WCML section of the Bakerloo line, what else spawns apart from all the static stock at Wembley and Willesden TMD?
There is an ai only steam tour I believe. Even better if you have the 38 tube stock, then that would mean 2 railtours running at the same time if you happen to know which service it is (idk either). I think a few electrostars too, but I'm not too sure about them since I mostly run on the underground sections and haven't really explored over ground
The frequency of regular services has been enormously increased. Something like a train every 4 minutes instead of every 15.
