Mac should work.
I was born in 1944, in 52 or 53 my parents took my sister and I to San Francisco form Los Angeles on my first train ride. I loved trains even then as I got my first Lionel set in 1948, a 2026 freight. We took the coast Daylight behind steam. I would guess a GS-4. Even double headed over the hill with steam. I looked out the window most of the trip just to see that steam engine. Summers I spent with my grand parents in Washington State. South of Yakima. One evening us kids were down by the Northern Pacific tracks and a row of what I think were 4-6-6-4s were pulled into a siding. All had their rods removed and I realized even at that age, they were going to their end. The other time I was fishing with my Grandpa just outside of Dunsmuir California and I heard something really big coming up the track. It was the only time I saw a working cab forward. I could see the track pushing down from the weight of that monster. Even my Grandfather was impressed. Don
