The JNR Class KE50 was a proposed 2-10-2 Santa-Fe-type steam locomotive intended to be operated by the Japanese National Railways.
History and design[edit]
The KE50 was proposed in 1943, intended as a supplement to the D52 heavy mikado type. The KE50 would've shared many design features with the D52 such as the same firebox grate, boiler diameter, cylinder bore and stroke, boiler pressure, cab and tender.
The differences the KE50 would have had with the D52 include the length of the boiler tubes, the axle load and would have had 12% more cylinder power then the D52. The diameter of the driving wheels would've been the same as the 9600 consolidation type.
Due to the scarcity of resources as the war conditions got progressively worse, the KE50 was never built. If it was built, the KE50 would have been the biggest japanese steam locomotive as well as the first 2-10-2 steam locomotive to be built in Japan.[1]
Classification[edit]
The classification consists of a "E" for the five sets of driving wheels and the class number 50 for tender locomotives that the numbers 50 through 99 were assigned to under the 1928 locomotive classification rule.
The "K" in the name might indicate "keikaku" (plan) in Japanese, essentially like an "X" designation used in aerospace designs.
