NS/Pennsy Bridge over Ohio River in Pittsburgh, PA

(1915 Bridge Hunter, 1890 Bridge HunterHistoric Bridges)

This is known as the Ohio Connecting Railroad Bridge or the Brunot Island Railroad Bridge.

I learned that this bridge is 70' above the water because somehow a woman drove her SUV onto the bridge and then fell to her death when the vehicle landed upside down in 20 feet of water. But her dog and cat survived. [post-gazette] I studied the satellite images and could not find a grade crossing of the rails in the vicinity. No wonder the police were "mystified."

Street View, 416' back channel span
Please follow the above Historic Bridges link to read how they used the material in the 416' foot span to cantilever the 525' main channel span during its construction to keep the shipping channel open. The piers were built wide enough for a double track because it was expected that the single-track through trusses would eventually be replaced by double-track trusses.

The Bridge Hunter page for the 1915 bridge shows the main span being floated into place. This contradicts the cantilevered construction technique described in Historic Bridges. So I paged through the eBook trying to find the picture. It turns out the picture on the 1915 Bridge Hunter webpage is wrong, but the picture being on the 1890 webpage is correct. This is how the initial single-track span was built along the shore and then floated in place.

Wean United/United Engineering & Foundry/William Tod

Rick Rowlands commented on The Rust Jungle posting
[Again, notice the artist is making sure that plenty of black smoke is coming out of every smokestack. Unfortunately, that is probably rather accurate because I saw a comment while researching the Youngstown Car Co. that you could not see across the Mahoning River Valley because of the smoke in the air.]
In addition to Mesta, William Tod also made steel mill equipment. I knew that steel mill equipment included rolling mill stands and ladles. What I learned by studying William Tod is that it also included stationary steam engines to power those rolling mill stands as well as the blowers for blast furnaces and generators for electricity. "Engines weighing upwards of 700 to 800 tons capable of producing up to 30,000 horsepower were built by several manufacturers in the time period of the 1890s through 1920." Allis Chalmers was the other of the "big three" steam engine manufactures. The Tod history page describes two engines. The low pressure cylinders are 68" and 76". So the 250hp Vilter engine with a 24" LP cylinder that I saw was rather little. [TodEngine, History tab]

The Google Satellite image shows that the plant has been torn down, but both Bing's Aerial and Birds-Eye Views show the buildings. "At its peak in the early 1970s, the plant employed 1,300, but it closed in 1982....It was last occupied in 2011 by Youngstown Pipe and Supply" [Vindy] AbandonedOnline has a history of Wean United and several photos of the abandoned buildings. I particularly like this photo.

IC IMX Intermodal Yard

When the Chicago Produce Terminal became obsolete, IC sold the eastern part and converted the remaining part to an intermodal yard.

Dan Tracy Wow, IMX later used by the SP.Keith Peeples Looks like IC was ahead of their time. Some railroads were still loading circus style thru the seventies.
[I-55 is on the right, so we are looking East.]
David Wilson's Photoset has two 1988 photos when the land was the ICG IMX intermodal yard: looking east and looking west. The second photo also shows both smokestacks on the Crawford Generating Plant. It also shows the lift towers for the Western Avenue Bridge.

Google Earth set to 3/26/1999
It looks like it was still being used when this 1999 image was taken.

It is no longer being used, but not because the land was needed for something else. Some of the tracks still exist.

Youngstown Car Company

The reason for studying this company was not so much for the product but for this photo and the fact that the main building is still standing. Their product were little carts that were used in plants to move material from one stage of processing to the next stage. Please access the link in the caption for more information on the product.

TheRustJungle, "Republic Steel's number 2, 3, and 4 blast furnaces in the background. This was part of the William Pollock Co. collection on Ohio Memory, so I assume they built the furnaces."

Note that the land between that plant and the Mahoning River used to be one of several steel mills that lined both sides of the river.

Retail Coal Bunkers

When studying old maps of railroad branches in Chicago that are now abandoned, many were surrounded by industry. (That is why the branch existed.) And it was common to find companies that sold various grades of coal because homes were heated and factories were powered by coal. (Gas in the 1800s was manufactured from coal and was used for lighting, not heating.)

These were retail companies that delivered coal with horse and wagon. Later coal was delivered by truck and the density of retail coal companies dwindled. The development of natural gas pipelines that could deliver gas to each household killed the retail coal company business.

People took pictures of trains, but not of coal bunkers. Fortunately, one is in the background of this picture.

Also note the ice company that helped supply ice for the icebox that was in each household.

CSX/B&O Bridge over Scioto River near Chillicothe, OH

(Bridge Hunter, no Historic Bridges, Satellite)

Mike Dlabay updated
Renick Sub., former Wellston Sub./CH&D at Chillicothe, Ohio Bridge 128 over the Scioto River after the portion of line from the side of the bridge I'm on east to VA Jct., Vauces, was taken out of service and then abandoned. Bridge collapsed in later years.

Street View
According to the satellite view, there are trusses hidden by the trees on both sidess so this was a five truss bridge.
A Flickr photo shows it was in operation in 2008.
