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.

Thomas Madrigal greasing a locomotive in the roundhouse, Rock Island R.R., Blue Island, Ill. April 1943. View full size. 4x5 Kodachrome transparency by Jack Delano for the Office of War Information.
Could be either a 4-8-2 or 4-8-4. The first series 4-8-4 (5000 class) had Bakers gear and Alligator crossheads. Second series (5100 class) had Walschart gear and multiple bearing crossheads.
I think this is a Rock Island 4-8-2. Based on the sheer size of the locomotive and the Baker valve gear (though partially disassembled here) and the distinctive casting above the man's head. The CRI&P's 4-8-4's were big too but didn't have the same valve gear.
Shows the working part of a steamer, any guess as to the wheel arangement?
