As the connection is currently via the headshunt from the line which
runs through the yard to platform 11, it would probably be quite
expensive as a stand alone project. Either the old connection to
platform 10 would need to be reinstated, cutting the car park in two,
or the junction with mainline upgraded. There would also probably have
to be facilities for coupling / uncoupling units as running a four car
train from Watford Junction - Euston in the peak would not be a good
idea.

Presumably you could uncouple and leave 4 in the platform while going
to St Albans and back? Could form the basis of a half-hourly all-day
Watford shuttle to remove local stops from the longer-distance stuff,
as I believe is the end game.

That, or make it "u"/"s" at Watford. As it's a separate platform, it
wouldn't be hard to enforce.
