The Royal Scot class steam locomotive No 46121, 'Highland Light Infantry, City of Glasgow Regiment'. The water spraying out from the locomotive is due to the Dillicar or water troughs. Water troughs were installed at various locations so that locomotives could pick up water without stopping. Photograph by Bishop Eric Treacy. Treacy was often allowed special acces to many areas denied to other railway photographers. He also befriended many of the footplate crews, occasionally persuading them to create special smoke effects for the camera.
