There were two locomotive cranes, 20 ton Browning diesel-mechanical locomotives, 1941. They also had a Whitcomb engine. Tracks ran around the drydock and had connections to warehouse.
The cranes handled material for ship repairs as well as unloading supplies from ships at the other piers. The locomotive moved a small number of cars of these supplies from the piers to the large warehouse. One of the cranes went to Central Plata. The trackwork was
36″ gauge.
