In the repair shed, workers get busy trains ready for more work. One locomotive gets a coat of fresh paint. An overhead crane lifts a locomotive off its wheels.
Workers use blowtorches to fix the wheel section.
Another crane lifts out the diesel engine itself so the workers can clean and repair it. The repair sheds stand in a large circle around a huge turntable. It points the cars to one of the sheds. There is a locomotive on the turntable now. The workers have just fixed its engine.
