Supplied by Gorden Allen, Network Rail's track maintenance engineer based in Appleby (Cumbria) they were taken on 9 Jan inside Blea Moor and Rise Hill tunnels on the Settle - Carlisle line. They form round the ventilation shafts from natural water seepage rather than from snow and ice melting out in the open air and dripping down.
As well as icicles there is also a build up of ice at track level.
The first three are Blea Moor, the last is Rise Hill.
