First Phase of Major Tunnel Works Now Complete
The first phase of major refurbishment works to Bowshank Tunnel is now complete.
The works, which started in October 2013, saw the Borders Railway construction team carry out masonry and concrete spraying. Only around one tenth of the old brickwork needed to be removed or replaced.
The second phase of work, which is due to start soon, will see the construction team lower the floor of the tunnel by 400mm. This work will be done ahead of the track slab being laid later in the project.
The 200m Bowshank Tunnel structure will play a vital role in connecting the new railway, and joins the 62m Torwoodlee Tunnel in being one of two historic tunnel structures being refurbished to help bring the structures up to modern standards.
Hugh Wark, project director, Network Rail, said:
“Much of the work we are doing at the Bowshank and Torwoodlee tunnels involves strengthening what is already there, with only a small proportion of the brick work actually needing replaced; it really goes to show how well built the historic structures along the line are!”
“The next phases of work will ensure that the tunnels help serve the railway for many years to come.”
