The deep cutting is well lit at this time of the afternoon and 170413 casts a long side shadow as it climbs the 1 in 102 1/2 gradient. The service is 1A78 1529 Edinburgh to Inverurie.
The reason for me coming out approaches, DRS 37409 hauling Observation Coach 975025 "Caroline". This special working is 2Z02 0950 Inverness to Edinburgh via Aberdeen.
The loco is named "Lord Hinton" for Christopher Hinton, Baron Hinton of Bankside, a British nuclear engineer who supervised the construction of the World's first commercial nuclear power station. The observation coach is named "Caroline", doubtful that is it named for the pirate radio station, Radio Caroline!! http://www.radiocaroline.co.uk/#home.html
