On my O gauge railroad, I have the following Santa Fe engines that I ran:
- Alco-Ge S2 switcher (two of them, and I actually ran both road numbers).
- GP7.
- RSD5.
And, I have the following Santa Fe engines that I rode behind:
- 2900-Class 4-8-4 (which was double-heading a bobtail rednose F7 in 1952)
I have, on order from Sunset, bobtail rednose F7 A-B-B units that I rode behind as well as ran. I ordered road number 307, which I actually ran at 90 MPH on more than one occasion, and thoroughly enjoyed, as it was an outstandingly good runner.
I also ran Alco-GE RS1 2394, which Atlas has just produced, but I really don't have use for an RS1 out on the plains. The real 2394 was a "dog" anyway.
And I think Atlas produced EMD SW1200 2437 several years back. I do not have the engine, but, in real life, I "made" my Engineer seniority date on the 2437, on the top end midnight switcher at Hobart Yard, in Los Angeles.
