Why so few SD.80 MACS?

Eric: This is an interesting coincidence. My father was also a career officer, though in the Army, and also up from the ranks; in fact, when he was commissioned in 1940, he was the youngest commissioned officer ever in the Army. He served through WWII and the Korean War, on Omaha Beach the afternoon of the first day. His education was practical, and so of course, was mine, learning construction beginning at age 6. I take it you work(ed) for SP; I worked for KCS. <br /> <br />The only thing I know that D&RGW did differently with its SD40T-2s was the water cooling on the radiators, and the application of Vapor Corp.'s PTC, which made them equivalent in tractive effort to a Super Series locomotive, such as an SD50. I think that is the sole difference, but who knows, maybe they used different injectors or governor settings, too. Everyone I knew was really, really happy when the AC4400CWs showed up, because they REALLY pulled, and had air-conditioning and a nice cab. No worn-out weather-stripping on the doors. <br /> <br />Alaska Railroad used PTC as well, but I don't think very many other railroads did this at the time. Later, SP used Maxitrac (spelling?), which was the same thing as PTC, but probably a better piece of electronic hardware. WC used Q-Tron, also the same thing, but even better, because it replaced most of the electrical cabinet. <br /> <br />I should add that I also enjoy these conversations. Unlike many railroad forums, this one has turned out polite, friendly, and generous -- and that's because of the people who use it, not anything we do at Trains.
