Midland class 700
London, Midland & Scottish class 1F
Great Britain 1869 315 produced
The Midland Railway's class 700 consisted of 315 0-6-0 goods locomotives designed by Matthew Kirtley. Most of the class was built by Dübs from 1869 onwards. Typical of this time, they had double frames and inside cylinders.
The Italian Rete Mediterranea bought 50 of these machines from the Midland, but they were only delivered after the FS was founded in 1905. There they were called gruppo 380 and were phased out in the 1920s at the latest. During the First World War, 78 Midland locomotives were put into military service. The last machines were taken over by British Railways and decommissioned by 1951.
