About the Photos

Our holdings include hundreds of glass and film negatives/transparencies that we've scanned ourselves; in addition, many other photos on this site were extracted from reference images (high-resolution tiffs) in the Library of Congress research archive. (To query the database click here.) They are adjusted, restored and reworked by your webmaster in accordance with his aesthetic sensibilities before being downsized and turned into the jpegs you see here. All of these images (including "derivative works") are protected by copyright laws of the United States and other jurisdictions and may not be sold, reproduced or otherwise used for commercial purposes without permission.

Round and round she goes

These wheels show a mix of eras. The wheels with a "pie plate" backing are steel, as all railroad wheels are today (in the US, at least). The wheels with the ribbed backing are made of iron. Those ribs are actually cooling fins to assist in cooling wheels heated by braking action.

Iron wheels date back to the earliest days of railroading. They had a bad tendency to develop cracks that, if left unresolved, would cause the wheel to break up. The railroads were constantly replacing such wheels. Old photos of shop facilities always show wheelsets all around that have been removed from cars. Iron wheels caused many wrecks and killed more than a few people over the years. It's a wonder why they weren't banned from interchange until the early 1950's.

Visible on the ends of the axles are the large brass bearings. These turned in journals filled with lubricating oil. The so-called friction bearings are now banned from interchange also. They have been replaced by roller bearings; much less maintenance needed.
