In focus – bridges, tunnels and viaducts on the railway

Wales Severn Tunnel electrification works

We’re responsible for the 40,000 bridges, tunnels and viaducts on Britain’s rail network. Many are from the Victorian era, and looking after some of the country’s most celebrated structures is both a privilege and a challenge.

Although maintenance is important, that’s just one part of our work. There are many more passengers today than when the rail network was first built, so we have to modernise and adapt our infrastructure as part of our Railway Upgrade Plan, to pave the way for better journeys.
