Refreshing the Trains

As part of the London Underground multi-million modernisation programme, all 106 Northern Line trains
have now been refreshed.

The refresh involved:
Deep clean of the interior
Electrical component upgrades
External new paint job
Fitment of safety flaps over emergency help points
Full interior repaint
Installation of warning ‘door-closing’ lights
New flooring
New safety signage
New seat covers
Removal of passenger door controls
Updates to the passenger information system/install new cab end LED displays
Wheelchair priority area installed

The signalling system has also been upgraded as part of the lines improvements. This will enhance the Northern Line for many years to come and make journeys on the line more comfortable and pleasant.

The refurbishment was carried out by Alstom who originally built the trains back in 1995.

New Features for Passengers
Class 172 trains was first introduced in September 2010. They replaced aging Class 150/1 trains which were inherited from Silverlink when London Overground took over most of their network.

These trains were ordered by London Overground as part of a multi-million investment programme to bring the network up to today’s standard. As part of the deal of new trains, stations were staffed from the first train to the last, heavily refurbished and modernised.

These trains have many new features and benefits for passengers:
Air conditioning
Audio and visual announcements
Formed of 2 coaches
Enhanced CCTV
More standing room
High back seating throughout
Standard and perch seating
Wheelchair accessible – priority area
Wider plug doors

There are 8 units in service, numbered 172001 to 172008

Future of the Class?
The Gospel Oak Branch has recently been electrified and new longer Class 710 trains will be introduced once testing has been completed. Since creating this page, the Class 172 trains have now been cascaded to West Midlands Trains.
