Most of the photos on this site were extracted from reference images (high-resolution tiffs, 20 to 200 megabytes in size) from the Library of Congress research archive. (To query the database click here.) Many were digitized by LOC contractors using a Sinar studio back. They are adjusted by your webmaster for contrast and color in Photoshop before being downsized and turned into the jpegs you see here.

Roundhouse at the Chicago and Northwestern Railroad yard, Chicago. December 1942. View full size. 4x5 Kodachrome transparency by Jack Delano.
The engine closest is a C&NW M-1 class 0-6-0 switcher built in 1916; the second looks like a C&NW 2-8-0 number 1756 Class Z freight engine built in 1910 and last one looks like a C&NW M-1 class 0-6-0 too. Can't read the number. The M-1 0-6-0s were interesting engines---the C&NW had many built from 1905 to 1917. The early versions were lighter and less powerful than the late versions --- yet they all bore the M-1 class and same pay level for the crews. Trivia.
Superb. Jack Delano has a new fan. Absolutely brilliant.
