Data from 1946 Beyer, Peacock catalogue hosted on Martyn Bane's website at [] (accessed 21 May 2006). See also "4-6-4 Tank Engines, Netherlands State Railways", Locomotive Magazine, Volume 19 (15 December 1913), pp. 272-273. Works numbers were 5856-5858, 5862-5866, 5868-5873 in 1916.
As reported in Locobase 7510, fourteen of the 40 locomotives ordered for the Staatsspoorwegen in the Netherlands were cancelled in 1914 because of reduced traffic. The British War Department's ROD requisitioned the undelivered set and used them to haul both military ambulance and troop trains and regular civilian passenger trains in France until the end of the war.
Having no particular need for the class, the ROD sold them to France's Chemin de Fer du Nord, which numbered them 3.871 to 3.884. SNCF's creation in 1938 led to their designation as class 232.TB and new numbers 232.TB 1 to 14. Two were retired in 1946, the rest withdrawn in 1950-1951.
