Network Rail engineers have constructed what is believed to be the first ‘beaver pass’ in the country under the Highland mainline.

The new tunnel has been constructed to help the protected species pass under the railway and to help prevent flooding issues caused by the animals building dams across the railway’s drainage culverts under the line.

As part of the project an additional 45mm pipe has been inserted through an existing larger culvert drain with wild mesh fitted either side to protect the railway while still allowing the movement of wildlife.

The Tay catchment around Perth has a growing beaver population and is a recent example of an area where their impact was felt on the rail network and a solution was needed to a flooding issue caused when a resident pair of  beavers damned a culvert under the track.
