37701 slogs up the gradient past Grovesend Colliery Loop on 8 January 1994 with the 6E07 10:55 Coedbach to Immingham containerised coal. This is on the Swansea District Line, which is principally a freight route, which bypasses both Swansea and Neath. At this time 37701 was allocated to Cardiff's FCKK Railfreight Coal pool, so this would be a typical job for the heavyweight loco.
