A superb reminder of the sadly missed rail blue era. 47615 Castell Caerffili / Caerphilly Castle passes under the A423 Oxford ring road and approaches Hinksey Yard on 21 June 1986 with the 1M20 14:57 Poole to Derby service. The loco was one of a number of 47s given names in connection with the GW150 celebrations the previous year, a fact noted on the small plate that can just be seen below the nameplate. Alternative liveries were starting to appear by this date, but here we have a complete rake of nine Mk2 vehicles in matching corporate colours.
