Well quite. All of the above are multiple platform stations at which some
services from one direction terminate.
AFAIK, The new Heathrow 123 will be the only 'conventional' LUL through
station (e.g. one 'up' platform and one 'down') from which the number of
trains in each direction is unequal.
Slonebridge Park & Harlesden have unequal numbers of LUL trains in
passenger service serving them...
