Part of the Thameslink Resilience Programme, the blockade involved remodelling the track layout at Balcombe Tunnel junction and the removal and replacement of track.

Usually, as part of Network Rail’s sustainability policy, materials that come out of upgrade sites are returned to a recycling centre at Whitemoor, Westbury, Cambridgeshire, where they are re-graded and offered back for use on the network.  

While delivering the upgrade at Balcombe, the team noticed that although the track was no longer suitable for use there, it was of a high enough quality to potentially be re-used somewhere else, without regrading or reconditioning.

Andrew Wood, Network Rail’s senior commercial scheme sponsor, South East Route said: “When renewing the switches and crossings, we usually need to renew the plain line leading to those switches, but when we surveyed the plain line track at Balcombe Tunnel Junction we realised it was in sufficiently good enough condition to re-use elsewhere in a siding rather than recycle.”

Limited access to stabling points for On Track Machines (OTMs) in the Sussex coastal area has been a long-standing challenge for Network Rail’s Supply Chain Operations team. Eastbourne provides an ideal location for stabling points across the south coast.

The track was deemed as suitable for use on sidings which removed the need to transport it to Westbury, carry out work on it and then return it to the south coast.

Andrew Ripley, senior project operations manager (Southern and Anglia) said: “This is a great win-win for us, from an operational perspective, not only do we reduce the fuel costs for the OTMs by storing them in Eastbourne, but we also increase the potential working time window for work in the future by having better machine availability.”    

“Environmentally speaking, less fuel used means lower carbon emissions and reusing the Balcombe track saves on the cost of procuring new track for the Eastbourne stable. It wasn’t of the standard required for a mainline, but it was fine for sidings where trains travel at low speed. The Balcombe track is probably good for another 50 years.”

Over time, the improved access to machinery will lead to better track maintenance being carried out more quickly. Good track maintenance means fewer passenger delays and a better passenger experience.  

As part of the re-installation of the sidings work was carried out to remove overgrown vegetation and to tidy up some walking routes.
