Built in 1914 at Swindon Works in Wiltshire, England, the steam locomotive Princess Victoria (4048) remained in service until 1953. On February 28, 1922, HRH Princess Mary was to marry Viscount Lascelles, future Earl of Harewood, and a locomotive was required for the royal train. The logical choice would have been an existing engine in the same class, Princess Mary (4046), but she was under repair. Instead, the Great Western Railway took her nameplates and put them on Princess Victoria (4048) for one day.
Though it’s slightly out of focus, I love the atmosphere of this small snapshot (1.75 x 4.5 inches) by an unknown photographer.
