Steam locomotive, number 79, of the Detroit, Toledo, and Ironton Railway on a slightly elevated track, next to a coal car.in a train yard. Worker is examining and possibly oiling parts of engine drive. Scene shifts to interior of locomotive maintenance shop where men work on a train car parked next to a locomotive. Scene shifts, again, to view from rear of moving train as it traverses route along the valley floor, from vicinity of Spargursville (AKA Spargurs) to Bainbridge, including bridges over Sulphur Creek , Alexander Hollow Rd, and both bridges over Paint Creek between the two towns. The train passes a tender connected to some sort steam driven machine (probably a pile driver as they are working on trestles). Also shown are box cars converted into bunk houses used by the work crew, which appear to be parked at Storms, only 6.9 miles from Summit, where the work is likely being undertaken. . The film ends at the Bainbridge train station. (Note: regarding the reference to work going on at Summit. Although not seen in this sequence, the track there was so steep that trains had to be broken down and moved up a few cars, at a time, to the top, where the train was then reassembled before proceeding.)
