Crosby Tunnel is a large tunnel that is located west of Crosby, connecting said town with Knapford. It is approximately one mile in length.


The Railway Series

Crosby Tunnel was cut by the Wellsworth and Suddery Railway (W&SR) in 1912 following the agreement made in that year to amalgamate with the Tidmouth, Knapford and Elsbridge Light Railway (TK&ER) to form the Tidmouth Wellsworth & Suddery Railway (TW&S). The tunnel, originally cut for a single line, was opened out for double track in 1915 when the North Western Railway took over the TW&SR.



  • The tunnel has gone through a few changes:
    • Series 6:

    • Series 23:
      • A passing loop and a hill are added on the Knapford side of the tunnel.
