A double surprise on the Rhymney Line on 8 July 2019. After being held at a red signal just out of sight amid the bushes, 37025 Inverness TMD & 37421 get under way again and approach Bargoed Viaduct with the 3Z36 15:47 Rhymney Sidings to Cardiff Canton Sidings crew training run. A pity the earlier sunshine had now disappeared!
