Network Rail has completed a £1.8million programme of work on the Mallaig line at Lochailort.
Starting in February of this year, the project delivered by Network Rail and QTS was required after flash floods in the summer of 2020 washed away 262ft of railway.
The initial phase of the improvement work involved installing a new concrete drainage tunnel, or culvert, next to the existing Allt na Criche bridge that carries the Allt na Criche burn under the railway.
Engineers removed 800 tonnes of material from the existing railway embankment in preparation of the new culvert being installed.
Significant undertaking
The majority of material removed was then recycled on site for other elements of work.
Installation of the 63.3 tonne culvert took place in the spring during a 78-hour period of continuous working.
The railway embankment was then reinstated before 130ft of new rail was laid on 200 tonnes of new ballast.
Jeremy Spence, Network Rail’s programme manager for the work, said: “Our work on the Mallaig line at Lochailort was a significant undertaking, given the sheer size of the culvert and the scale of the excavation involved.
“The successful delivery of the work and the significant benefits this project delivers will help tackle severe weather incidents that are increasingly frequently presenting challenges to the railway industry.
Improved resilience for years to come
“By protecting the railway from extreme weather events, we also mitigate the risk of the impact of this for passengers, freight customers and lineside neighbours.
“I would like to thank our contractor QTS as well as the local community for their patience and support while we delivered this critical improvement to Scotland’s Railway”.
Andy Steel, QTS operations director, said: “The work carried out at Lochailort over the last five months has hugely improved the resilience of Scotland’s railway for years to come.
“Our team undertook some important work during this period, including the installation of a structure that will help manage waterflow to safeguard the integrity of the railway during heavy rainfall.
“We appreciate the patience of the lineside neighbours and the travelling public during this works.”
