British Railways was being re-branded and undergoing a
major image transformation from the mid 1980s. The various regions were replaced
with business sectors. The southern suburban lines came under the London
& South East Sector, which also included all southern main lines and
commuter routes from London to destinations within about an hour and a half
from the capital. Some main line EMUs received the sectors livery of two
tone brown with an orange stripe but none of the suburban units were so treated.
The sector was further re-branded and relaunched as Network Southeast on
June 10th 1986. With the new image came the promise to smarten up train,
stations and just about everything else with the sectors colours of red,
white, blue and grey. New trains were promised and a facelift for those older
ones required to see further years of service. The NSE livery was quickly
applied to the 455 fleet and in due course older units of HAP and EPB stock
were also repainted.
The first significant addition to the network came on
May 16th 1988 when the Thameslink services were introduced. These ran from
destinations in the south such as Orpington, Sevenoaks, Brighton and Croydon
to Blackfriars and then via the snow hill tunnel (which had been rebuilt
and reopened after years of closure) to link up with the Midland region at
Farringdon where the trains had access to the midland main line to serve
destinations to Luton and Bedford.
To provide these new services brand new units of class 319 stock
were built at York Works. They had the same body shell as 455 stock but with
a much improved interior layout including high backed seats and toilets.
The traction control was of the 'Chopper' system trial on latter built 455/9
units. The 319s worked on the 3rd rail south of Farringdon and were equipped
to use the AC overhead lines for the journey north from there. The first
batches were standard class only but a second batch with first class
accommodation were built in 1989/90.
The advent of Thameslink rendered the Holborn Viaduct
terminus redundant and it was closed on January 26th 1990, being demolished
soon after.
Further new units were delivered to the central section
during 1990/91 to eliminate the last examples of non gangwayed EPB stock
from those lines. These were 24 two car units of class 456. They were compatible
for multiple working with the 455 fleet and were based on the same bodyshell
but with 319 style interiors, including a toilet.
In 1992 plans were announced to privatise all of Britain's
railways and the passenger businesses were split into smaller companies.
The southern suburban lines came under three companies whose boundaries closely
followed those of the former Southern Railway divisions with a fourth company
formed by splitting off the Thameslink services which by then no longer served
any destinations in Kent. The south western division became 'South West Trains',
the central division became 'Network South Central' and the south eastern
division became 'South Eastern'. The later section was the recipient of the
last EMUs ever built for the British Railways Board. The class 465 and 466
Networkers were built at York Works and Met-Cam of Washwood Heath between
1991 and 1993. The 465s were four car units with the 466s two car sets. All
units featured three phase traction equipment, plug doors, saloon interior
with toilets and on board information displays. They were the completion
of a promise of new stock made back when Network SouthEast was formed in
1986. Their entry into service brought about an end to the last of the EPB,
CAP and HAP units.
The four company franchises were let to private companies
in 1995 and 96; Thameslink was bought by it's own management and South West
Trains became owned by the Stagecoach bus group whilst both South Eastern
and South Central passed into the ownership of a French based company called
Connex.
At the time of writing all three divisions have new stock
on order ready to enter service soon into the start of the 21st century.
