37427 Bont Y Bermo emerges from Dinmore Tunnel on 31 January 1989 with the 1V08 09:15 Liverpool Lime Street to Cardiff Central Regional Railways service. At the time this line saw regular Class 37 use in lieu of the booked Sprinter diagrams. Unfortunately this uninterrupted view of the twin bores of Dinmore Tunnel from a convenient nearby road bridge has been completely lost due to uncontrolled tree growth.
