37405 emerges from the fog at Ystrad Mynach on 10 December 2005, as it heads down the Rhymney Valley with the 2F18 10:15 Rhymney to Cardiff Central Arriva Trains Wales service, on what was supposed to be the last day of Class 37 haulage in the area. The loco passing between the two signals certainly makes an interesting picture, slightly compensating for the gloomy conditions!
