    In the 50s, freight hood units received the same scheme as switchers, "zebra stripes": RailPictures.Net Photo » Atchison, Topeka & Santa Fe (ATSF) EMD GP7 Cab units received blue and yellow: RailPictures.Net Photo » Atchison, Topeka & Santa Fe (ATSF) EMD FT In the 60s, all freight power started receiving blue and yellow: RailPictures.Net Photo » Atchison, Topeka & Santa Fe (ATSF) EMD GP7 RailPictures.Net Photo » Atchison, Topeka & Santa Fe (ATSF) EMD SD45 RailPictures.Net Photo » Atchison, Topeka & Santa Fe (ATSF) EMD F7(A)

    I think the actual situation is more complicated. I'm somewhat of a Santa Fe fan, but mostly post-1970, so can someone expand on this?

    The last steam in revenue service on ATSF was in 1957. In '56 and '57, the only steam in use were 4-8-4s and 2-10-4s, about five units. They were used only in helper service in Abo Canyon during the summers.

    Here is the most complete ATSF steam roster I could find. A 2-6-6-2 group was in there (the bottom of the page) but I can't find any photos of them.

    Thank you. Now, to narrow it even more,any pictures of an EMD F/7 A & B in freight colors in years 1954----->1960 ?
    I would like to use such engines hauling freight while a lash of up of redbonnet F/7 A+B+B+A hauls a passenger consist such as this one:


    Any suggestion?

    Here is some very good information on Santa Fe’s F units: Santa Fe Railway Historical & Modeling Society - The F-Unit Pages In the first chapter on the second page about the passenger F7s it says, that even in the 1950s some of the red silver warbonnet F7 spent a lot of time in freight service. So it is absolutely prototypical to have some redbonnets at the front of a freight train.

    Unfortunately, I can't tell an F3 from an Fxwhatever.....:cry: Only thing I do know is that the warbonnet paint scheme was the best scheme of any railroad hauling whatever was coupled behind it....One of these days, I'm gonna have a Super Chief streaking over the rails of my LC&P..!!! And everything else better get outta the way..!!! :mrgreen::mrgreen:

    My personal collection of 1950s ATSF diesels began with the Geeps which are Lindsay brass castings mounted on Athearn chassis, then painted and decaled. The FTs are repainted early Bachman shells on Athearn chassis and the B unit is a Cary casting. The blue/yellow freighters are all repainted Athearns. The slightly detailed PA, PB units are Athearns. I also have new Bachman F-7 A-B-B-A units (not shown) that are being detailed and are to be painted soon. Lots of hours and little money spent on this collection.

    Well, a late-production F3 does look almost identical to an early F7, and I can't tell them apart. Santa Fe also modified most if not all of its F3s to look like F7s - or was it to look like F9s?

    I just noticed how old this thread is. I had forgotten what I had written in this thread, but after reading it over, I have some further information to add to some of the questions that have been raised.

    First, my friend Jim Fuhrmann has done a lot of research on the disposition of the f-units on the Santa Fe. He has been able to trace every f3a, f7a, and f9a on the roster. He could not determine what happened to the b units, but I suspect that they were never removed from the roster, just canabilised as a source of spare parts for the cf7s.

    Santa Fe's F-units (F3, F7, F9 and CF7 Rebuilds)

    Roger, there was a lot more to converting a f7 into a cf7 than removing bodies and replacing them. The problem was that the body is the frame on a f7. What Santa Fe did was build a brand new frame and body to put the mechanical and electrical components into. The early cf7s had round roof cabs, which were sectioned out of the old f unit bodies. The later units received "Topeka Cabs" which are a Santa Fe design. They look like standard Emd cabs except that they are taller to allow more head room for the crew inside.

    As far as the 2-6-6-2s are concerned, there was an article in Trains Magazine back in the 1980s, if I remember correctly, on Santa Fe's "Prairie Mallets". Santa Fe's mallet fleet lasted only about 10 years. They did not look like anything anybody else ever ran. The Santa Fe tried 2-6-6-2s, 2-8-8-2s, and 2-10-10-2s about 1910, maybe 1905. I think by 1920 all of the mallets had been used to build 2-6-2s, 2-8-2s, and 2-10-2s. Basically they got 2 locomotives out of each mallet. Santa Fe not only articulated the frames on their mallets, but they also put a bellows type hinge in the center of the boiler! Unfortunately, the bellows tended to fill with water which froze in the winter! All of the mallets were compound units where the steam for the rear drivers was exhaust steam from the front drivers. The problem was that even when they didn't have problems with the boiler hinges, they still didn't work very well. In addition most if not all of the mallets had "whale back" tenders. It was not until WW2 when the Santa Fe got some USRA 2-8-8-2s from the Norfolk & Western that they realised that they needed to put bigger fire boxes in a mallet type to generate enough steam for what was essentially two locomotives on one frame. They thought about building some big mallets following WW2, but by the time the war ended, they had made the commitment to convert to diesel.

    Some became slugs that were often used with CF7s. Some became Locotrol receiver cars.
    I thought they discovered that the F-unit frames were stronger than expected, and all they needed was new reinforcing side sills?

    Thats what I thought I read in that one post also but may have missed something. Interesting that the big boys (EMD and GE I think it said) didnt want to touch this project.

    The f-unit frame was more like a modern unit body automobile frame than a separate frame body construction. When they cut off the cab down to the sills, I don't think there was much frame left. That is why the new side sills were so deep compared to the sills on a gp9 for instance.
