There is a crossover on the Queens Park side of Kilburn High Road station.
This was used, in the other direction, when the line into Euston was
blocked for a while. This means that reversing at Queens Park wouldn't need
any track alterations.

It's also got fourth rail and used by the Bakerloo the Bakerloo is
disrupted in the underground section (otherwise Bakerloo trains would
block the route to Euston as well).

That would mean platform 4 being used to reverse and platform 1 not
being used at all in normal service.

Or with an extra crossover, they could use platform 1 too and thus
have two platforms for reversing.

In fact ISTR talk of LU wanting to connect up platform 4 so that it
could be used by through Bakerloo trains, as terminating trains being
tipped out in platform 3 tend to cause blocking back along the line.
In that case platform 1 would be the sole terminal platform for the
NLL.
