�The new portion was completed in 1921 for dealing with the largest engines. In this there are sixty pits, each 100 ft. long, which are served by an electric traverser, and there are four overhead electric cranes, each capable of lifting 100 tons with a span of 75 ft. This new portion, in addition to dealing with the repair of heavier and longer engines and rail motor cars, accommodates the pits for the erection of new engines.
