Train improvements | Southeastern

A major fleet improvement programme is underway at Southeastern, which will help us to provide a better, more reliable and sustainable railway.

The investment in our rolling stock includes upgrades to the current fleet, as well as exploring how we can replace the older trains that operate on our Metro routes.

You can find full details about our extensive improvement programme below.

The target

Better Metro: we have 30 of our City Beams in service providing lighter, brighter, and spacious trains for customer across south-east London and Kent. We are also retrofitting accessible toilets. In addition, all 36 trains in our Class 376 fleet are getting a mid-life interior and exterior refresh.
Better Mainline: the Class 375 upgrade completed at the end of March 2024, bringing new lighting plus at seat power and USB sockets to these trains for the first time. The transfer of an additional 13 Class 377s began in December 2024.
Better Highspeed: the Class 395 upgrade, which includes a full interior refresh, will complete in 2025.

The fleet improvement programme

Metro trains

Southeastern announced an important step towards delivering a multi-million pound investment to improve our fleet of Metro trains.

Across our network, we are working with our partners at Network Rail, to improve performance, expand our timetable, enhance our stations and increase the number of staff available.

The final piece of the jigsaw will be the replacement of our aging metro fleet.

Southeastern is inviting competitive offers for new, refurbished or modern cascaded rolling stock for the benefit of customers and taxpayers. In this video our Managing Director explains the potential benefits of new rolling stock for our customers.

This could be the largest investment in the Southeastern network since the introduction of the highspeed service in 2009 and is a key part of Southeastern goal of building a better, more reliable and sustainable railway.

These trains would run on our Metro routes to London terminals across south east London as well as selected locations in Kent including Dartford, Sevenoaks, Grove Park and Gillingham.

The precise details of the improved fleet will be developed during the next stage of the procurement process but improvements could include:

Improved accessibility to maximise unassisted boarding – developed alongside the RSSB, Network Rail and manufacturers
Brighter and more spacious interiors to provide more space for more customers on our growing railway
Improved air conditioning to provide a better and more comfortable environment, particularly as our summers become warmer
Improved customer information to keep customers up to date and help them to plan any onward journeys
More reliable trains with improved acceleration and braking to help deliver a more punctual and low cancellation railway
Equipped with batteries to keep trains running in the event of power supply failure as well as enhancing safety in stations, depots and sidings

The City Beam (Class 707)

The City Beam was introduced onto our network in 2021 and these light, bright and spacious trains have proved to be very popular. We now have 30 five-car trains available for service on the Dartford, Hayes, and Grove Park routes. We are also retrofitting accessible toilets onto all of these trains for added customer comfort.

Having a full fleet of 30 City Beams means that even more customers on our busier Metro routes will be able to enjoy travelling on our newest trains.

Our fast trains – Highspeed (Class 395)

The Class 395 operates on our two highspeed routes from London St Pancras via Ashford and via Ramsgate. In partnership with the maintenance company Hitachi Rail and the owning company, Eversholt Rail, we are carrying out a £27m upgrade of the 29 trains in the fleet.

This upgrade will future proof the UK’s only highspeed passenger fleet, which has already delivered record levels of reliability, customer satisfaction and a £1 billion+ boost to the Kent tourism economy since 2009.

The £27m improvement programme includes:

Full interior refresh, with new carpets, new seats and change to the layout that will assist people with reduced mobility.
At seat power sockets for mobile and laptop use.
Enhanced LED lighting.
More CCTV to aid on-board safety and monitor space availability.

When the upgrade has been completed it will bring the Class 395’s up to the very latest standards, and ensure that comfort levels, accessibility and information provision are as high as they possibly can be for our customers.

Our star trains – Electrostars (Class 375, 376 & 377)

All 112 of the Class 375 ‘Electrostar’ train fleet that operate on our routes serving Kent, East Sussex and mainline London stations have received at-seat power sockets, including USB points, new LED lighting and energy metering.

The at-seat power sockets provide commuters and leisure passengers with the ability to work or browse on the move, without worrying about running down the battery on their device.

We are also adding at-seat power and USB sockets to our Class 376 fleet as part of a mid-life refresh. In addition, all 36 trains are getting energy efficient LED lighting, an interior paint plus refurbished seats, and a new, blue exterior wrap.

More Class 377s are also joining our fleet with a total of 13 units due to be available for customers by the end of 2025. These newer trains will help provide a more reliable service and a better travel experience with their air conditioning, at-seat power sockets, and improved onboard information.

Why are you looking to replace or upgrade the Metro fleet of trains?

We need to replace a significant proportion of our older train fleet, which is becoming more difficult and expensive to maintain and also lacks modern accessibility and customer facilities.

Our oldest trains are known as Networkers and were first introduced into passenger service in 1992 – the same year the Ford Escort was the country’s best-selling car.

You wouldn’t typically keep a car for that long – and our trains cover tens of thousands of miles every year.

As well as the better journeys for customers; improving the fleet will also be better value for money to taxpayers as it would reduce maintenance and lease costs and, in time, encourage more people to travel by train.

Will these trains be accessible?

We are clear that any new or replacement trains must improve customer accessibility and help to remove barriers for everyone to travel by train.

Those bidding to manufacture new trains have been tasked with showing how they would provide level access and/or unassisted boarding at stations across the Southeastern network as defined in the Persons of Reduced Mobility (PRM) National Technical Specification Notices (NTSN).

The precise details of how this can be achieved will be developed as part of the procurement process. However, to ensure we provide the best possible solution for our customers, we are already working with the following:

Network Rail – Owners and maintainers of the railway infrastructure, including tracks and platforms
Rail Safety and Standards Board (RSSB) – The railway’s independent safety, standards and research body
Manufacturers

Our Metro fleet must be able to safely and reliably call at over 200 platforms across our network. However, as our railway has been built over many years to different standards our platforms vary in height between location and some platform heights vary from one end to the other. In addition, some are curved which can increase the distance between the train and the platform edge, too.

Improving accessibility, particularly the introduction of level access and/or unassisted boarding is a challenge for the whole railway system – but it is a challenge we are working to overcome.

What are the timelines?

We recognise much of the current fleet is tired and in need of upgrading. As such, we are working with urgency.

We have started a formal procurement process with a number of manufacturers, financiers and leasing companies to assess the available options to replace some or all of our Metro fleet of trains.

As and when more information is available, we will ensure our people, stakeholders and customers are informed accordingly.

What are the environmental benefits of upgraded or newer trains?

Will Southeastern be buying new, upgraded or existing trains outright?

How many new or upgraded trains are you planning to introduce?

Are you planning on replacing the Main Line and highspeed fleets?
