The timetable was unveiled as Swiss train builder Stadler confirmed VolkerFitzpatrick as winning contractor yesterday for the site at Gosforth in Newcastle.

The depot will accommodate new state-of-the-art trains for the Tyne and Wear Metro, which are set to enter passenger service from 2023.

Nexus, the public body which owns and manages the Metro, named Stadler as the firm that will build, service and maintain its new trains for 35 years at the rebuilt facility.

Robert Baxter, Managing Director at Stadler Rail Service UK, said: “The appointment of VolkerFitzpatrick to build a new Gosforth depot is a highly significant milestone for the Nexus project, heralding the start of this exciting project in the north east, which will see the transformation of rail travel in the region.

“Stadler has pledged to support the regional economy and involve as many Tyne and Wear-based companies in the project as possible.

“We are keen to use local suppliers for materials and services required for the depot re-build, the manufacturing of the new trains and the ongoing service and maintenance of the trains on the patch.”

Paul Lilley, VolkerFitzpatrick’s Operations Director, said: “As a leading constructor of rail depots, we have extensive experience of managing such projects and look forward to helping Nexus further enhance their network and create a state-of-the-art facility in readiness for their fleet of Metro trains being introduced in 2024.

“Working in collaboration with Stadler, Nexus, other key stakeholders and our supply chain, we aim to demonstrate a one team approach for delivering this project, with sustainability and innovation at the forefront of the design, which will change the current landscape and bring a focal point to the local area.”

Work will involve the safe demolition of the old depot, open since 1923, clearing the site, followed by building the new facility.

Work is scheduled to begin later in the year, with most of the building work set to be completed by 2025.

The planning has been configured to enable the legacy fleet to continue successfully operating from the depot, while the construction work takes place.
