Here is another bit of info for anyone modeling a cofc train in the '70s or early '80s. Sea Land had some custom built gen sets using large Deutz diesels for power. They were lift off units with a large fuel tank in the base, and setting on a skid, so they could be loaded by crane or fork lift. they would put two 89' flats next to each other with two reefer boxes on each, then the gen set would be mounted on the end of either car closest to the end of the other car. I should mention the gen set would sit cross ways on the car, so it only took up about 3 feet of space. Two reefers from the car with the gen set would bel plugged into it, and the two on the adjacent car would have their cords strung over the coupler, and plugged into the gen set. This was before the advent of double stacks, but I think that after the double stacks came in, Sea Land would still have them load live reefers on 89' flats with the gen sets. By the 90's when Sea Land was sold by RJ Reynolds to CSX, I think they got a lot more conventional, going to all electric units, and using gen sets that clipped on to the front of the reefers, 1 gen set per reefer.
