This shows just how quickly the weather can change in Wales. Shortly after taking a picture of Welsh Highland Railway NGG16 Class 2-6-2+2-6-2 143 at Caernarfon on 21 October 2014, this torrential downpour occurred while the loco was taking water. This unusual viewpoint, looking down from a footpath that runs above the line, is in marked contrast to the same loco (in a different livery), at the same spot twelve years earlier.
