Class 377 "Electrostar"
photograph by Colin Duff
Electrostar unit Nº377112 formed the rear of an eight car
formation departing Clapham Junction for Victoria on 11th October 2003
|As mentioned in the section on the class 375 the South Central portion of the third Connex
batch was been adopted by Govia. These units are to the original Connex
specification. South Central subsequently placed further orders. This is
thought to be a pragmatic act since other rolling stock manufacturers have full
order books, plus the major de-bugging has already been done by Connex and c2c.
The Brighton lines also currently suffer from inadequate power infrastructure
for the full potential of these units to be exploited and some units have been
delivered and put into secure storage. South Central took the opportunity to
re-specify slightly their Electrostars, the most significant technical changes
being the use of Dellner couplers, resulting in a re-designation to class 377
and less generous seating.
In 2003 the overall 182 South Central fleet was planned as
377/1 4 car dc only units formed DMSO-MSO-TSO-DMSO - 64 units
(2+2 seating 377101-119, mixed 2+2 and 3+2 seating 377120-164)
377/2 4 car dual voltage units formed DMSO-MSO-PTSO-DMSO - 15 units
(details to follow)
377/3 3 car dc only units formed DMSO-TSO-DMSO - 28 units
(These are part of the original Connex order, they were delivered as Class 375
and converted to Class 377 by changing their couplers to the Dellner type.
They have 2+2 seating.)
377/4 4 car dc only units formed DMSO-MSO-TSO-DMSO - 75 units.
