The British Rail Class 376 Electrostar is a class of electric multiple unit passenger train that was manufactured by Bombardier Transportation at its Derby Litchurch Lane Works. It is part of the Electrostar family, which are the most common EMUs introduced since the privatisation of British Rail. The units were ordered by Connex South Eastern and introduced in 2004/2005 by South Eastern Trains to replace Class 465 and Class 466, which were transferred to Outer Suburban services to Kent to replace the Class 423 slam-door trains.

Design

Class 376 at New Cross

It is a derivative of the Class 375 Electrostar specially designed for use on the high-volume metro routes running from Central London, and through Southeast London to Kent. The changes are mostly focused on increasing the trains’ capacity and decreasing station dwell times. The Class 376's doors are wider to allow more passengers to board at once, and are metro-style sliding pocket doors which are faster and more reliable than the Class 375's plug doors, although they do not close flush with the bodyside and hence are less aerodynamic and do not provide as much thermal insulation. The units have 2 sets of double doors per side in each carriage. Also, these trains do not have air conditioning, with hopper style windows available for ventilation. In order to provide more standing room, the trains also have fewer seats, more handrails, and no on-board toilets (South Eastern promised to provide additional facilities in their stations to compensate) and, as a consequence, these trains are limited to in-service journey times of 1 hour.

Class 376 units have five coaches, and unlike the Class 375, they have full-width cabs instead of gangways at the ends of the train; as a result, it is not possible to walk between two coupled Class 376 units. The cab front is also smooth and ‘step free’ to reduce the dangerous problem of train surfing in Southeast London.

Despite being numbered in the 300s, currently all Class 376 units can only operate on the DC third rail network. However, like most newer trains in the United Kingdom using third rail power, one carriage in each unit has a recess in its roof where a pantograph can be fitted, so as to allow for the units to run additionally on overhead AC traction power if ever required in the future.

Maintenance

All Class 376 trains are allocated to Slade Green Depot, ^[4] but due to the high volume of work there, these trains are sent to Ramsgate EMUD for routine maintenance. ^[5]

Accidents and incidents

A train formed by units 376 002 and 376 035 was one of eleven trains that stalled and became stranded in the Lewisham area on 2 March 2018. Passengers self-evacuated the train after conditions on board became intolerable due to lack of heating, toilets and communication. ^{[6] [7] [8]}

On 10 July 2018, 376 030 partially derailed at Grove Park depot. ^[9]
