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.

3rd Rail & Pantographs

Yes, GeeBax, this was a third rail system, and the power rail is seen 2' 4 1/4" outside the running rails to your left of the engine.

The small pantograph was used in terminal switching areas where an overhead power supply was placed above complex track arrangements such as slip switches and double crossovers which made it difficult, or impossible, to place third rails to assure continuous power supply to locomotives.

Third Rail

While the tunnel track on the right has the third rail in shadow, you can see it pretty clearly on the other side, to the right of the incoming electric engine. The Detroit tunnel operation was with 600V DC until the diesel electrics took over.

Ether Power

There does nor seem to be any overhead power feed to the electric locomotive, even though it has a very small pantograph. Was there third rail power in the tunnel?

Getting the Royal treatment

In the center background you can see the rooftop sign for Royal Salad Dressing. It was mde by Horton-Cato Mfg. Co., which was founded by two English gentlemen (hence the "Royal") in Detroit in 1877. They also made Worcestershire sauce.

Diesel Fuel: 2018

This railway tunnel from Detroit to Canada is still in use, although steam and electric engines have been replaced with diesel-electric locomotives. Not far away is the infamous Michigan Central Station, which is to be restored. You can check out photos of the station here.

Deja Vu

We've seen the sign for Royal Salad Dressing before. Oh, and Engine 7501 too. Love the different perspectives.
