Trains to London: Severn Tunnel electrification problems [BBC News]

Date: 28/06/2019

Full electrification of the main south Wales to London railway is in doubt as engineers on the £2.8bn project have an 'issue' electrifying the Severn Tunnel. The kit holding electric wires above the track in the four-mile (6km) tunnel is failing because of the salty conditions under the Severn Estuary. Network Rail has spent three years and what is thought to be close to £20m to prepare the tunnel for electrification. Specialists in electric rail have been brought in to help solve the issue.
