Rope Running through a Roller above a Horizontal Sheave
This is the horizontal sheave, and the water brake, at Engine House Six. The water brake was used to control the rate of descent when rail cars moving down the slope were heavier than the weight of rail cars moving up the slope. Engine House No. 6 is listed on the National Register of Historic Places, as part of the Allegheny Portage Railroad National Historic Site.Galleries:Allegheny Portage Railroad, MachineryKeywords:allegheny portage railroad, engine, engine house, fiber rope, gallitzin, horizontal sheave, pennsylvania, roller, sheave, steam-powered engine, water brakePhoto Location: Allegheny Portage Railroad National Historic Site, PennsylvaniaPhotographer: Dr. Roy WinkelmanDate of Photo: 11/25/2011Device Make: CanonDevice Model: Canon EOS 5D Mark IIOriginal Dimensions: 5616×3744Picture Orientation: LandscapeGPS Coordinates: 40°27'22.18"N 78°33'01.88"WPicture Number: 15808
