The main, largest, building was called "The Big Shops" by the locals..
It was said to be the largest building in the world when it opened in 1904!
LV built steam locos there until 1925, then it became the LV's main (and eventually only) locomotive maintenance shop,
used right up until the end of the LV in 1976.
Conrail never used it.
Demolition began in November 1987 and was complete by the summer of '88.
Photos of it being torn down:
I have more photos, including the interior, if anyone is interested..
The building was 360 feet wide by 747 feet long.
(I have poor scans of some original drawings, just good enough to show some basic detail)
The entire complex as a whole, all the buildings together, was "The Sayre Shops"..
Today only five original LV structures still stand in the Sayre yard,
The "Hammer Shop" (Later the Assembly hall)
The "Freight car repair shop"
The "Store house"
(building names from the map in the Archer book)
and a 5th building that isn't on the 1904 map in the Archer book..not sure what it was, but it was a LV building.
The large blue building that says "GE Railcar" on it isn't a LV building, that was built by GE in the 1980's..
Four companys use the Sayre yard today:
Norfolk Southern still owns and uses the mainline tracks along the edge of the yard, some of the yard tracks, and the tracks approaching the yard from all three directions.
(Four rail lines once radiated out from the Sayre yard, today it's three.)
GE Railcar uses the largest part of the yard, they repair freight cars, and use a lot of the yard for freight car storage as cars are rebuilt.
Rynone Industries uses the "Store House"..they make furniture, kitchen cabinets and such.
And the "Guthrie-1" medical helicopter has its base where the roundhouse once stood.
The new shortline "Lehigh Railway" comes close, but doesn't actually enter the Sayre yard proper.
