Dyer & Butler, a part of M Group Services, has successfully undertaken a programme of drainage works in Balcombe Tunnel on behalf of Network Rail.
The works were undertaken as part of a nine day blockade of the Brighton Mainline which saw works undertaken around the clock at 26 sites by Network Rail and its industry partners, including Dyer & Butler.
Dyer & Butler, a multi-disciplined engineering services specialist focused on essential infrastructure including airports, railways and highways, were based at the Balcombe Tunnel site which is one of the longest tunnels on the route.
The Victorian brick culvert drainage system had suffered from a build-up of silt and other debris, along with some brickwork degradation. As a result, flooding after rainfall was damaging the signalling and power supply system. Their works included repairs to the drainage system and removal of the silt and other debris.
Network Rail South East managing director John Halsall said: “I know it’s been difficult for passengers and I am really grateful that so many changed their plans for the week to enable us to concentrate the work in this way. The alternative would have been 84 separate weekend closures, so this has been much more effective for them as well as for us.
“It will be worth it in the long run as we’ve been able to complete major work to the ageing infrastructure which has caused so many delays in the past, as well as repairs in the Victorian-era tunnels which were prone to flooding. All of this means we can provide a more reliable service that passengers deserve and can depend on.”
Dyer and Butler director of rail Chris Darlow commented: “We’re proud to have been part of the delivery of this extensive programme of engineering works which will deliver significant reliability benefits to passengers on one of the busiest routes in the country.”
