"CR's Conway yard was located northwest of Pittsburgh along the Ohio river. This former PRR yard remained the largest railroad yard in the world from the time of it's expansion in the 1950's until 1980." [ConrailPhotos, many of the photos are just locomotives, but there are some overview shots]

| Erik Nordberg posted The SIA Newsletter (a benefit of membership) includes reviews and links to new publications. A recent issue included a review of a history of Conway Yard. ------------------ The Pennsylvania RR’s Conway Yard was one of the most important railroad yards in the U.S. This book explores why the rail yard was built and studies the complex series of PRR lines that fed coal, coke, steel, and other products from the Pittsburgh region into and out of the yard. PRR lines from the north funneled ore from Lake Erie ports into Conway for use in the steel mills of Pittsburgh, Youngstown, and Ohio River towns in northern W.Va. and eastern Ohio, while coal, coke, and finished steel products flowed north. Two distinct phases of the yard’s evolution are examined: the beginnings in 1883 and the modern yard circa 1957. The scrap dock, reclamation plant, river-to-rail terminal, and computer controlled humps are documented. The story also involves junctions, the meeting places between divisions or railroads owned, held, or controlled within the Pa. system. This system of lines was a contributing factor for the building and development of the PRR’s primary yard at Conway. The book covers the Eastern Division of the Pittsburgh, Fort Wayne & Chicago Ry., the Pittsburgh, Youngstown & Ashtabula RR, as well as the Cleveland & Pittsburgh RR. Portions of the Panhandle, Conemaugh, and Monongahela Divisions located in Pittsburgh are also included. Further coverage of PRR’s lake ports in N.Y. and Ohio provide broader context. An accompanying CD offers 45 large-scale maps in PDF format. Ken Kobus, Frank Napoleon, and Steve Titchenal. Conway Yard: Keystone of the Pennsylvania Railroad. Pa.

| Craig Hensley Photography posted It’s Hump Day! So here’s a shot of the old dual hump at Conway yard during the Conrail Era. Photo by Phil Kent. Ron Mele: The Pennsylvania Railroad built the Conway hump yard in the mid-50s. Conway tied several main and branch lines together and the double humps were required since there was a lot of traffic flowing east and west. Conway's role as the prime system yard continued through Penn-Central and with Conrail to some degree. But the yard has a diminished role under Norfolk Southern, therefore the need for just a single hump. Chris Bocchi: One of the things that few people know is: parking your car at Conway was a great way to ruin the paint! I worked out of Conway for two years and the combination of wheel dust from the retarders, unburned diesel hydrocarbons and UV from the sun baking the paint caused the car to turn an unlovely black/brown. My 1998 Charcoal Green Mustang turned nearly black! Erich Rudolph: I spent a lot of time at that yard. If it was hazardous material it went through Conway. |

| Craig Hensley Photography posted I made a stop at Conway on my way home from Pittsburgh a couple years ago and snagged a few different shots of the shops. Here’s a different angle of the turntable with the shop switched on it, and a variety of different locomotives. You also get a good visualization of the hump with a switcher and slug set as well.

| Samuel Pelaia from HistoricPittsburgh The Conway Yard, built by the Pennsylvania Railroad at a cost of nearly $35 million, was the world’s largest and most advanced automatic freight classification yard. Cars were directed to the proper track by an automatic system, which could set up a route of up to eight switches. The eastbound line of the railroad ran adjacent to the Ohio River (right) and State Highway 88 bordered the yard on the left. The central tower for the entire yard, the general yard office, the dormitory, and other related facilities for trains and personnel are located in the large structure in the left center of the photograph. |

The tower on the right would be the hump yard tower. Is the tower on the left is a mystery. Is it "West Conway Tower?"
