    From Frisco company photos are the birth of 4300 at the West Shops.
    I'm trying to figure out how to arrange the photos in the proper order but no luck, so you'll have to use your imagination.
    The boiler is shown prior to the smokebox being attached and the courses not riveted together or staybolts installed. It is newly fabricated from nickle steel and will have the steam dome and base from 2-10-2 No. 57 put on and riveted down. The dome has the Baldwin builder's number stamped on the front side and by doing this, the Frisco will have tax advantages by claiming it as the "old" boiler from the 57.
    When the 4400s came along, they actually used the Spot engine boilers.

    Don, We appreciate you posting the photos, those are very interesting. In one there are several people around 4300. It would be great if we could do that now, maybe 1522 in St. Louis or 4500 in Tulsa. There are other locomotives out there that would work also.

    I like seeing photos of steam locomotives as they are being built. Have seen some with rows and rows of locomotives, all in various stages of completion. Don't know where I saw the photos, guess I'll have to Google.

    My favorite class of Frisco steam due to the aesthetics and Frisco-originated creativity in effectively building these from scratch.

    Might be for another thread but the photo on the transfer table: when these were built, I had assumed it was all completed in the steam erecting hall at West Shops. But this photo seems to point to the locomotive being loved to another building? Would be curious to have someone with more knowledge of the West Shops to chime in.

    Thanks, Don, for a nice New Year's present.

    This should have read "moved," not "loved." Quite the Freudian Slip, I suppose. A big thanks to an FFF (Fine Frisco Fellow) for discretely letting me know offline.

    A question for Don, Karl, whoever ........
    Is it possible the Frisco 4300's were the greatest performing SLSF steam locomotives per unit of its weight? Seems to me they sure had a great reputation, at least when they were new.

    ps - Back from our Holiday cruise on Oceania's M/S Riviera. Wow - it was terrific!

    Ken,

    Attached is an article that I posted previously. In short, it's all about how one define his terms, and how the steam locomotive is used, i.e., fit for purpose. If you're talking about the modern Frisco steam freight locomotive operating at the top of the its HP curve, total HP vs Total Engine weight, then I would rank them in the following order:
    1. 4500
    2. 4300
    3. 4200, 63" drivers
    4. 4200, 64" drivers
    5. 4400

    When a locomotive is operated for extended periods below the speeds at which their maximum horsepower is produced, then there is a waste of the locomotive investment dollar. Remember, officially for freight trains, the Frisco was a 50. mph railroad. A 4500 running up Dixon Hill at 15 mph is not producing the HP it was designed to produce.

    Nice write up Karl. I think to an extent, Frisco tailored the size of the freight trains to keep the speed up which in a way helped the engines to be closer to their "G" spot as I used to call it on 1522. Helpers made the ruling grades more livable too. There is so very much that we don't know today on how they operated "then".
    Dad used to tell a story of having to detour over the Missouri Pacific with a troop train, long, all heavyweights with a 4300. The MP pilot kept bloviating about their 5300s being much better engines than the 4300 that Dad said "Here, sit down and see what a REAL engine can do" The pilot came out on the throttle and was listening and watching. Pretty soon, he started looking sheepish and started easing off on her and finally got up and said "Damn, these are something else".
    I really wish steam had stuck around another five years on the Frisco. I would have been more mobile than a 26" balloon tired bike and could have gotten out and appreciated them more.

    This is a terrific thread. Being born in 1954, I pretty much missed steam. It's great being able to learn about operations, usage, etc.

    Thanks,

    Karl:
    What are the units used in your evaluation?

    HP/unit weight
