I was unable to take pictures inside DLW so this is all I can publish at this point.
Hercules. (My comments: According to National Railway Museum, where sister loco Phoenix is on display, Hercules is preserved at Jamalpur. However, due to lack of serial # on this display, it is not possible to verify if this is original Hercules or not.)
Specs for Miss Muffet. (My comments: Class CS #776 on Eastern Bengal State Railway was built in 1932 by Yorkshire Engine Co., Sheffield. U.K. Her sister loco #773 was built in 1927 by W.G. Bagnall, Stafford, U.K. Source: Indian Locomotives Part 3 by Hugh Hughes.)
1940 stock GE DE loco. It was a common site on WR at Mumbai.
