I don't think that's true. The track layout at CULG implies that the
through platforms aren't reversible:
http://www.davros.org/rail/culg/picc...ayout...giving you 1
reverser at a time instead of 3 at Cockfosters.

It is quite possible to have 3 reversers (east to west) at the same time
at Arnos. Only platform 2/3 can reverse west to east though.
