D. F. Sarmiento Railroad's #6580, a GM-EMD GR12W built in 1962, leads a freight train leaving Haedo North Yard and bound to General Roca Railroad's Kilo. 5 Yard. The train is crossing at level the four-track Sarmiento mainline during the morning rush hour, completely blocking the flow of traffic through those tracks and so haltering the every-six-minutes commuter train service for the small lapse it takes (if nothing goes wrong) to move the cars from the north to the south side junction to the branch that connects the Sarmiento and Roca railroads. And just behind the five flat cars used to give braking power to the train comes Baldwin-Lima-Hamilton RF615E #7018, original power of the train turned into a dead-in-tow unit after a mechanical failure.
