This double track tunnel is 110 yards long. It is between Barnhill Tunnel (to the north) and Alexandra Parade (to the south).
Formerly sidings approaching Blochairn Steel Works from the north passed overhead.
For the opening of the City of Glasgow Union Railway a quite lengthy portion of the Monkland Canal, which formerly bordered the southern edge of the Blochairn Iron Works, was deviated to the south to a location where the line passed underneath in a tunnel specifically built through the new canal deviation. Short portions of the original canal route were left on either side, severed by the new railway's alignment.
