It seems very bizarre to have a short section of unelectrified line on an
otherwise electrified system especially when its the obvious place for
stock
transfer. Unless for some reason they required complete electrical
seperation
between the AC and DC sections.

According to posts elsewhere a year or two back it is a simplified system
which does achieve electrical separation, and therefore can only be used for
irregular movements, it is not designed for timetabled operation.

The normal means of transfer of stock is via a number of route options in
south London onto the WLL.
