Network Rail has officially opened a flagship maintenance delivery unit (MDU) at Barnetby – marking an £8.8 million investment and strengthening support for the railway in North Lincolnshire.
The purpose of an MDU is to provide a physical base for maintaining the rail network.
The site, which entered into service on Monday 1 June, was officially opened yesterday (Wednesday 10 June). It replaces outdated infrastructure more than 100 years old and brings together teams from Grimsby, Barnetby and Scunthorpe under one roof.
The two-storey, timber-frame building places sustainability at its core and was designed as flagship project under Network Rail’s Greener Railway strategy, supporting the company’s ambition to reach net zero by 2050.
Designers embedded sustainability into every aspect of the new building. The structure significantly reduces carbon emissions and incorporates air‑source heat pumps, triple‑glazed windows and rooftop solar panels, enabling Network Rail’s first net zero operation MDU.
More than 100 maintenance staff are based at the building, which features a mess hall, changing and shower facilities, accessible toilets, meeting rooms and office space.
The 9,000 square metre site has parking for 50 vans and 66 staff vehicles, with 22 electric vehicle charging points.
A biodiversity net gain was achieved through landscaping, planting 11 trees and more than 400 plants, and installing bat boxes. Acoustic fencing has been installed to minimise noise for neighbours.
The facility has already received national recognition, having been shortlisted for the Rail Business Awards 2026 in the sustainability and environmental excellence category.
Network Rail views Barnetby MDU as a blueprint for future maintenance facilities. Its design has already influenced plans for a similar development under way in Sheffield, showing how this investment is helping to shape the future of railway infrastructure.
George Drum, Network Rail infrastructure director, said: “Our new maintenance delivery unit at Barnetby is a significant investment in our colleagues, our operations and the future of the railway. It provides our teams with modern, sustainable facilities while supporting a key route that underpins both freight and passenger services across the region.
“We’re proud that the site is already being recognised nationally for its sustainability credentials, and that it is setting the standard for how we design and build maintenance hubs going forward.”
The project also delivered significant benefits for the local community. As part of the project’s social value commitment, planters were provided for the village and a defibrillator donated to Barnetby United FC. North Lincolnshire College students were given placements at the site with main contractor HBC Construction.
