A southbound EWS class 66 156 hauled permanent way drifts over summit at Ais Gill around the bend towards Garsdale head. In steam days the former signal cabin here would be a welcome sight for crews after the long climb up to the summit of the line at 1169 feet (356 m) above sea level at this lonely spot.

Today, little evidence remains there was ever a signal cabin here (right side of the line, probably where the white portacabin is) and reverse sidings that ran each side of the running lines. Thankfully, the Cabin is still in existence, preserved by the Midland Railway Center in Butterley and removed from here in 1982. This view is from a small access bridge which marked the end of the sidings and the Cumbrian/Yorkshire border.
