Network Rail has installed a new flood defence barrier to protect the main line from being disrupted by flooding to the north of Exeter. The barrier, which was installed at the end of May, is part of a £26.5 million programme to reduce the regular disruption to long distance and local Barnstaple (Tarka Line) rail services, that is often caused by flooding of the River Exe around the Cowley Bridge Junction area. In November and December 2012, the main line at Cowley Bridge was submerged, closing it for 11 days. Passengers endured severe disruption as buses replaced trains.
The new metal flood defence barrier can be quickly assembled across the railway when poor weather is forecast and stops the flow of the flood water. When not in use, the barrier remains largely unseen, which means the local landscape remains largely unchanged.
The first part of this project was the installation of large flood drains in 2018, which allow water to drain underneath the railway and safely away from the railway.

Thanks Ed. A couple of photos taken 9th May showing the storage box and fixing points (and the 1035 from Barnstaple). I guessed that's what it is but you've confirmed it!
