Two General Electric export-model U13C's perform switching duties at Ferrosur Roca Railroad's Kilo. 5 Yard. While number 6008 drags GM-EMD GT22CW #9012 and a cut of derelict and rust-laden freight cars out of storage, to the right #6031 classifies another cut with two cabooses in between. Both locomotives were built by G.E. Erie, Pa. Plant in 1963 as a part of a 45-unit order, and entered service in the General Roca Railroad to haul commuter trains for the next 30 years. From then on, a small group of 6 survived in switching and light road-freight service after being transfered to the Ferrosur Roca private operator.
