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 follows:
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.

    Notice
    A sign, or at least notice, of the times! A software/database warning notice seen in the cab window of unit Nº377402 warning operators that this unit is not to be coupled to a unit without selective door opening, nor to a unit with the A3 database nor any unit with software version lower than SP17.1... And you thought life was difficult when unit coupling restrictions were limited to the type of coupler, brakes and traction index! Seen whilst at Clapham Junction on 19th April 2005.
