Are the actual sub-classes split rigidly between the bits of the network
anyway? For example are there now some dual voltage units in regular use
on the East London?

Yes, it's happened regularly since the a.c. services commenced. Most
days there is at least one 378/2 working on the ELL.

And presumably more from 9th December?

Why? Queens Road Peckham to Clapham Junction is DC. Have they
put some AC between Surrey Quays and Queens Road Peckham?

Weren't the additional trains for the SLL service dual voltage units?
Bringing them into daily service means more dual voltage units on the
ELL service overall.

My point is that from an operational point of view dual voltage
is not required (unless they've put AC between Surrey Quays and
Queens Road Peckham). So why does Colin Rosenstiel think there
may be more dual voltage running down the ELL, unless that is
all that is available.

Based on this and other threads: There are insufficient DC only sets
to operate all DC only services.
