I was a little disappointed by the sound. The photo was taken at Lichfield Trent Valley High Level signal box, where the chord from the west coast mainline allows southbound traffic to climb up to the old South Staffordshire line to Burton upon Trent and Derby.
It's a tight bend, and an incline of around 1 in 30, so you would expect some noise - especially as it was pulling a class 57 (the reserve engine in case of failure). Somewhat different to last time I saw one move, screaming down the east coast mainline at 100mph pulling an express train - probably with Graham in 1st class![]()
