Are the ATO lines considered more for entry level / beginner tube drivers, and the older lines with more manual driving done by the more experienced drivers? Or does it not really work like that? For example does everyone start out on the Victoria line, with the more senior drivers eventually moving on to the Bakerloo etc?

Cor - that's pretty fascinating. Thanks for your answer! Would the depot with the 5 year waiting list be something like Chesham or Amersham, by any chance?
