Will the 3rd rail be lifted then?

The whole lot will probably have to be relaid anyway, to provide 4 platforms
at Canonbury and Highbury, and 4 tracks on the current 3-track section. I
can't see the juice rail surviving all that (except on the ELLX lines
between Dalston Junction and Highbury & Islington, as the ELLX will be an
entirely DC operation, and its trains, though in other respects essentially
the same as the new trains for the NLL, will be DC only).

Obviously under the arrangement for the ELLX up to Highbury &
Islington that has become apparent lately there's no need for the ELLX
rolling stock to have AC equipment, but I was under the impression
that all the new class 378 Electrostar trains for London Overground
were all ordered as dual system (i.e. AC & DC) stock - am I wrong in
thinking this, or has the order subsequently been amended?

The class 378 units will be split into two. The replacements for the
class 313 will be dual voltage. The 'extras' for the ELLX will be DC
only, at least initially, but will have passive provision for AC as
well. I wouldn't be surprised if all the units end up as dual voltage,
especially as the services for Phase 2 of the ELLX might change
depending on loadings after phase 1 is completed.
