DH Steam Era - Class D-3a

#522 (4-6-0 Double Cab) on May 1933 at Oneonta, NY


From the collection of Darren E. Hadley

 

#523 at Binghamton, NY {August 1937}

 

Darren, do you know the purpose of those apparent extensions to the firebox that partially cover the third main driver?

 

Sorry, no idea...

The Class D-3a engines (#521-524) are all rebuilds of 1904 D-3 engines (#504-507). So far I don't have any images of these in their D-3 configuration.

Here is D-3 #508

The D-3a classes were then rebuilt into Single Cabs in the late 1920's

 

Nexted up: D-3b
