Walton Burn Tunnel

Castlecary, Cumbernauld, Dumbartonshire.

Tunnel / Culverts (19th Century).

Tunnel carrying the Walton Burn under a railway embankment with a northern entrance that resembles a mine adit. It has been driven through limestone / sandstone strata that is exposed through the majority of the interior. It is brick / stone-lined and vaulted near its southern entrance.

An additional culvert, which is stone/brick-lined and has an unusual horseshoe-like shape in x-section, is present below the railway line just over 200m to the NE (downstream) at NS 78618 77410. This carries a small un-named tributary of the Red Burn.

The Walton Burn meets the Red Burn immediately north of the tunnel's north entrance, where a small waterfall is present.
