Described on the Hildesheim Peine Kreiseisenbahn (HPKE) website [] (first accessed December 2001; later http://www.hpke.de/, last accessed 12 October 2022); and "BLE 45 bis 49" in Wikipedia at [
], last accessed 12 October 2022. The locomotive database [
], visited 3 June 2005, shows the class all came from Krupp as follows:
Christian Lindecke [] (visited 28 November 2003) for data. Additional data from US Military Railway Service Equipment Data Book -- German Locomotives supplied by Allen Stanley from his extensive Rail Data Exchange in March 2004. Lindecke gives 1.92 sq m (20.66 sq ft) for the grate area; the MRS book insists on the specs figure, which equates to 1.83 sq m.
This was the 1921 version of the VIc superheated Prairie tanks (Locobase 5943). Information comes from [] (visited 2 March 2004). Additional data from US Military Railway Service Equipment Data Book -- German Locomotives supplied from the extensive collection of Allen Stanley (March 2004).
Christian Lindecke [] (visited 28 November 2003) for data. Additional data from US Military Railway Service Equipment Data Book -- German Locomotives supplied from the extensive collection of Allen Stanley (March 2004). Lindecke's data gives 2.12 sq m (22.81 sq ft) for the grate and slightly different heating surface data.
