The western portal of Drewton Tunnel is almost entirely buried with landfill and is situated in a chalk quarry operated by Stoneledge.
This end of the tunnel has considerable deposits of mud on the former trackbed washed in by rainfall as a result of local quarrying operations.
The tunnel regularly experiences chalkfalls as the lining inside deteriorates in the damp conditions.
The 83 foot deep Little Weighton Cutting has been completely filled in, as have other areas of open space around the eastern portal.
Despite its continual decay Drewton Tunnel is now home to a large number of bats.
