Train operator Northern is set to replace the "ageing" trains that operate between Harrogate, Leeds and York.
As part of its largest ever investment into its fleet, Northern could introduce up to 450 new trains across the North.
The new trains will be introduced on a phased basis, replacing the oldest units in the existing fleet, most of which have been in service since the 1980's and 90's.
In Phase One, the ageing Class 150 trains through Harrogate will be among those replaced first - and 12 electric three-carriage trains will be introduced.
Tricia Williams, managing director of Northern, said:
“Almost 60% of the trains in our fleet are between 32 and 40 years old and, while they’ve served the region well, it’s important we get the ball rolling on their replacement.
“It’s game-changing for Northern and will transform the look and feel of our fleet for millions of customers – and it also cements electric and battery as the long-term power source of choice for our fleet.”
It is expected the contract will be awarded to the successful bidder or bidders in 2026, with an aim to have first trains delivered to Northern by 2030.
Approximately two thirds of the existing fleet is targeted to be replaced in the next ten years.
New trains will be a mix of electric and multi-modal (diesel/electric) powered trains and prospective manufacturers have been asked to include battery-powered trains as part of their proposals.
Multi-modal units in the order will be capable of conversion to battery or electric-only operation during their lifetime, in line with the government’s commitment to deliver a cleaner, greener railway as part of its net-zero objectives.
By reducing the number of different types of trains, it will significantly simplify operations, help with staff training, and lower maintenance costs – all of which will help reduce taxpayer subsidy.
Rail Minister Lord Hendy said:
“This vital fleet upgrade will create smoother journeys and help Northern provide the services their passengers deserve.
“It’s also great news for our rail manufacturing industry and demonstrates that the pipeline for orders is strong.”
Future phases will replace the next oldest fleets as more new trains come off the production line.
The replacement fleets will incorporate and benefit from the latest technologies, designed to meet the needs of the customers of today and tomorrow, delivering higher levels of comfort, reliability, and overall satisfaction.
Removing diesel trains over time from service will demonstrably improve the local air and noise quality overall, and especially in locations where this is a concern.
Williams added:
“The new trains will support the government’s commitment to achieving Net Zero operations by 2050 whilst reflecting the reality that only 25% of the Northern network is currently electrified.”
Train manufacturers approached as part of this first ‘Invitation to Negotiate’ step in the procurement process are Alstom, CAF, Hitachi, Siemens and Stadler.
The timescales for the introduction of the trains will be developed as part of the procurement process, however, Northern has set bidders challenging targets to deliver as soon as possible.
