JNR C57 "Noble Lady" 

This class of 4-6-2 Pacific style locomotive was built from 1937 to 1953 as an improvement on the earlier Class C55 locomotive. They featured Boxpok Drivers and a boiler pressure of approximately 235 lb/sq. inch.  They were popular with their crews since they could be managed and maintained by the somewhat smaller-stature of Japanese railway men.   A total of 201 of these elegant locomotives hauled the express trains on the main lines all over the JNR rail network. Because of their graceful proportions - a long, low-slung slender boiler and high drivers - they were affectionately nicknamed the "Noble Lady" and were known by this designation to rail fans the world over.  

Since 1979, a number of restored “Noble Ladies" have seen service on local lines in Japan, to the delight of steam railway fans, where they create a sensation for railroad enthusiasts, both young and old.  The C57's built for Taiwan in 1953 were the last steam locomotives manufactured by Hitachi, and Aster has modeled a locomotive from this class as it would have appeared during the period between 1937 and 1940.
