Is there a reason why this is not just billed as part of the
Underground, especially since it will soon have some deep tube bits?
If the Underground can include the Chesham branch, why not the North
London Line? Do staff at Gospel Oak station get paid less than staff
at Chesham, in which case keeping the Overground separate from the
Underground is a divide-and-conquer wheeze against the rail workers?

What is now called the "Overground" is actually part of "British
Rail". The government put those lines out to tender and "Overground"
won it. Therefore, it's not part of Tfl as such - for instance it
works under National Rail rules/signalling and passenger
terms/conditions not LU.

Signalling and rules are of no relevance. The ATO lines are not declared to
be a different system to the driven lines, for instance.
