This photograph was taken at Beck Meetings, Dale House on the 20th December 1884 (according to its caption). Simon Chapman advises : ”It shows a train from Mr. Palmer’s Grinkle Park mine carrying workmen towards Port Mulgrave. The locomotives were ‘cab less’ to allow them to travel through the low tunnel under Ridge Lane.” The gentleman with the horse and trap has now been identified as Dawson Robinson the Loftus Ironmonger; perhaps on his regular round delivering to farms and villages in the area.
Many thanks to Simon Chapman for the update.
The tunnel at Port Mulgave did not need an engine house for rope haulage system through the tunnel to Dalehouse; within the tunnel was a self acting incline; full wagons coming down pulled empty wagons up. Please look at tunnelsuk.com (search port mulgave) photos in side the tunnel, show two tunnels side by side where wagons passed. I believe the engine house was used for pulling barges closer to the dock
