 A Class 156 Super-Sprinter formed the 1626 Carlisle to Leeds via Settle service (headcode 2H88).It could only proceed as far as Ribblehead railway station, about 12 miles north of Settle, as the lines from Ribblehead to Settle were blocked by flooding; so it had to return to Carlisle.The driver changed cabs as the train was now heading northbound instead of southbound, and proceeded back over the Ribblehead Viaduct, and on to Aisgill Summit, the highest point on the line at above sea level.
