What kind of engines were in the DL-109? Also, what type turbo charger did they have. I remember the Gulf Coast Rebel always had this engine when leaving St.Louis Union Station in the 1950s. I will never forget the sound. I was a youngster then but can vividly remember that thing chugging and whistling as it went under the 16th stret overpass. What a sound. It is ashamed no one saw fit to preserve this, my favorite, engine.
They came with twin Alco 538's ( later changing to the newer 539) with the swiss designed Buchi turbocharger.
