Ok - just want to check...

Is Oyster Pre-pay valid on the Bakerloo line between Queens Park and
Harrow and Wealdstone? Isn't this bit of that line different from
the rest of the underground?

Nope. All the stations between Queens Park and Harrow and Wealdstone
are either gated with UTS gates or have validators in the station
buildings, near the platforms.
