I think I am. Here is my list, all of course Milwaukee Road.
3 sets A-A or A-B-A F-3s....4 Trainmasters,...7 scale steam engines including 3 Berkshires. K-line was the best deal around with those scale engines and cars. They forced many changes in the O scale field including passenger car interiors, more detail on F units and Trainmasters to name a few. I miss them.
My other engines are a MTH electrics, 3 scale Little Joe's, 2 sets of box cabs 1 Bipolar and 1 Hiawatha Brass Weaver and set A-A Atlas FM. Don
