When he tripped the camera shutter and captured this view from an observation car platform, John W. Barriger, III had just bridged the Shenango on the rear of a westbound train easing to a station stop at Sharon, Pennsylvania. Having just exited the west portal of Erie Railroad bridge 81.04's two quadrangular Warren through-trusses on the Mahoning Division's First District, his railcar was right on the North Water Avenue grade crossing, and a mere two city blocks from a station stop. The nearer end of the skewed truss is marked, up high, with an 'ERIE' diamond sign. The bridge number and river's name are also painted on the end posts, as they also were for Erie bridges over numerous other rivers. This was the third (and last) time this train had crossed the Shenango in just over a dozen miles. The extra pair of rails across the spans was the gauntlet track that stretched less than 4/10 miles, from just beyond the east portal of this structure, past the Sharon station, to just west of the West State Street crossing. A train of gondolas is crossing the river via the New York Central (former LS&MS) Sharon Branch. The NYC also had trackage rights on the Erie between Sharon's Ferrona Yard (a third-of-a-mile east of this bridge) and Sharpsville. At this location, the Penn-Ohio state line is running nearly parallel with the railroads about six city blocks away, on a 300' hill out of view beyond the freight train. The river, the Erie and NYC will all bend together and cross into Ohio in just over a mile.      ---Courtesy of the University of Missouri–St. Louis; John W. Barriger III National Railroad Library.
