Harrow-on-the-Hill, at least for LUL trains (paired by direction from
Wembley Park and through the station, then paired by use on to Watford South
Junction. It's a bit more complicated, as the Chiltern Line from Marylebone
runs into the fast pair, while the Uxbridge branch leaves by a diveunder.
Effectively Colwich to Stafford, although there is only a double track
through Shugborough Tunnel.
I've lost track of the removal and reinstatement of the Relief Lines west of
Didcot, but effectively the GWML is paired by use east of Foxhall Junction,
but are or were paired by direction to the west.
AIUI something similar happens on the approach to Cardiff Central.
