I saw this at Hellifield station in 1984 with my dad, ( I was only 9 years old). I remember it distinctly. We expected Sir Nigel to arrive at Hellifield light engine and were surprised when it arrived (tender first) pulling a goods train also. Sir Nigel was facing toward Carlisle, Then some minutes later City of Wells arrived (facing towards Leeds) pulling a passenger train, (I think probably from Carnforth.) Sir Nigel then took the passenger train North over the Settle and Carlisle and we followed it in the car about as far as Ribblehead. I think it was Derek Soames (Signalman at Settle Junction) idea to use Sir Nigel to help the failed goods train. You can see him working in the box here .
