Network Rail called CML out to an emergency response on Thursday June 13th after the 14.34 London to Nottingham train ran into debris following a landslip and flooding on the GSM1 line near Corby. Up to 600 passengers were stranded, and a second train sent to rescue them also became stuck due to severe flooding on the line through Corby tunnel.
The first CML team of five from Works Delivery were on site within two hours of receiving the call, joining over 50 Network Rail staff who were hand digging debris off the flooded line. The initial assessment highlighted the need to stem the flow of water coming down the cutting slope and on to the track. The first response team of Craig Trewick, Nick Lockerbie, Mark Guest, Neil Thorne and Gav Morgan proceeded to trace the network of drainage ditches back from Pen Green aqueduct to clear vegetation and blockages from trash screens to enable the free flow of water through the drainage system. Having cleared the drainage systems, flood water dissipated relatively quickly.
The track is on the Corby to Melton Mowbray branch line and when the rescue train also became stranded the local fire brigade and British Transport Police put in place an emergency evacuation of the train. The passengers had now been stranded for eight hours and the CML team set up task lighting along the 800 metre route, cleared overhanging vegetation and helped passengers and their luggage board the waiting coaches.
By Friday morning at 7.00am Ian Blakemore’s Earthworks team including Jamie Plawecki, Aaron and Jordan Blakemore and Josh Chantry arrived with a rope access team to undertake repairs to the cutting slope, using a long reach excavator to remove debris and make the slope safe. The CML teams were under great pressure to work as swiftly as possible and their hard work meant the line was able to be re-opened by 7am Saturday morning. A team of watchmen monitored the cutting over the weekend to check there was no further movement or debris flow. Meanwhile back at head office Contracts Manager Lee Harrison was coordinating logistics to respond to the fast moving situation and maintain 24 hour cover.
Following on from the initial reactive works, the team the team have been busy installing a 50 metre long sheet pile wall and concrete pile cap to form a permanent barrier at the crest of the cutting, and reinstating drainage systems to prevent re-occurrence.
Ian Blakemore summed up the CML response. “It was very intense because of the risk of further flooding. The Works Delivery and Earthworks teams pulled together as one to complete the work as quickly as possible.”
