The locomotive seen in this film is one of the world's oldest. The "Lion" originally pulled passenger and freight cars between Manchester and Liverpool for 20 years, starting in the 1830s. It was rediscovered in 1923 and restored to working order for the centenary of the Liverpool and Manchester Railway in 1930. It is now on exhibit in the Museum of Liverpool, after spending many years at the Museum of Science and Industry in Manchester.
Helena Pickard played Queen Victoria in the film. Her son Edward Hardwicke would later play Queen Victoria's son Albert, Prince of Wales (the future King Edward VII) in The Pallisers: Part Seventeen (1974).
