Datum Monitoring provided around the clock emergency support to Network Rail on a partially collapsed main line railway bridge.
Specialists from the Lancashire-based structural and geotechnical monitoring team were drafted in to ensure the operators were able to keep lines open.
The UK’s leading geotechnical and structural monitoring experts were called to the scene at Barrow Upon Soar after a large section of the Grove Lane Bridge collapsed at around midnight during repair works.
The bridge collapse made national news as it occurred just 20 minutes after the London St Pancras train to Nottingham had passed under it on the Midland Mainline.
Datum CEO Rory O’Rourke said: “We were able to play a key role on site in relation to track safety and keeping the lines open.
“We provided readings on a regular basis which allowed the Amey Examiners and NR to build up data which could then be used to determine when the track speeds could be increased .
“Our work involved both manual monitoring, the installation of automated equipment and continual monitoring until the bridge was made safe.
“The operation is a demonstration of the excellent work carried out by Network Rail in the event of such unexpected incidents and highlights how Datum are perfectly placed to react swiftly and efficiently.”
Four lines pass under the bridge, two that serve the local Leicester to Loughborough service and two that serve the faster London to Sheffield services.
It is understood the bridge partially collapsed around midnight on August 2nd 2016 though Network Rail were able to re-open all lines from 10.30am the following day.
Journeys between London St Pancras, and Nottingham, Leicester and Derby – as well as the Leicester, Lincoln, Grimsby routes – are all affected.
East Midlands Trains said the closure of the line would affect all its services north of Leicester including to and from Chesterfield and Sheffield.
