    Hi gents,

    I am currently building a 1/12 scale live steam 2-8-0, and would like to attempt to model Frisco #988. I have seen the photo that RICHCRAB posted, and was wondering if anyone out there had more photos of this particular engine. Profile views, close up views, whatever, would help. At the moment I'm working on the mechanics, but as soon as I finish that, I'll be ready to tackle the details.

    Thanks in advance!

    This should help a little. Let me dig around in my collection and see what else I can find for you.

    Thanks, Don! I appreciate it. With those closeups, it's clear that those had walschaerts valve gear. I was a bit nervous that I might have to redesign my steamer for Baker valve gear, but they just put everything close together and from the original photo I couldn't tell.

    If anyone has more references/photos, I would greatly appreciate it. The Loco I am building has square counter weights (a la 988/989), and walschaerts valve gear and D-valves, so if there are other locos in the same class with the same setup, let me know!

    Also, what make is this locomotive? Would help to know :)

    I thought I had posted these already, but must not have clicked on submit. One of these is a repeat, but I scanned the negative. These are taken by SR Wood and Preston George, negs in my collection.
    There are also some low numbered 1200s with this Walschaerts conversion to slide valve cylinders.
    GN also had some 2-8-0s with the same arrangement.

    I'm really intrigued by the wooden barrels on the pilots. in the OKC shots. Did these contain water for the brakemen?

    Yes, indeed. Look closely and one can see the dipper.

    Ah, there 'tis. This detail might have to find its way onto a yard switcher in our HO-Scale version of KC.

    Chris - Same thing in a diesel era shot in Joe's "Frisco Power" on page 229. See the ice water barrel and dipper on NW2 SLSF 262.

    Thanks for these phenomenal photos! More photos would be of even more assistance!

    Can anyone tell me what size pilot wheel this loco might have had? I am assuming the 988/989 had 51" drivers and the pilot looks to be approximately half the diameter of the drivers, which puts it around 25.5", but I'm thinking it is probably 24" or 28" (over the tread).

    I am thinking of taking a trip to the Museum of Transport here in ST Louis to take a gander at the Baldwin Consolidation that they have... I know there will be differences between the road names, but at least I can get an idea of Baldwin's construction methods, etc.

    I need to machine new crankpins for the drivers as well as two new axles, and I can start erecting the frame. Can't wait!

    You can check out my work at: http://walshlocomotiveworks.blogspot.com/

    Does anyone know of any basic Baldwin Consolidation blueprints? Erection drawings would help!

    Thanks,
    Mike

    The 970-989 Class 2-8-0's had 55" drivers and they had 30" pilot wheels. Built in 1906, locomotives 971-975, 982,983, & 985 were sold to the NOT&M and numbered into the 101-110 series of that road. The remaining locomotives survived nearly to the end of steam on the Frisco.

    Retirement dates:
    970 NOV 1948
    976 SEP 1950
    979 NOV 1948
    980 MAY 1948
    981 NOV 1948
    984 JUN 1951
    986 SEP 1950
    987 JUN 1948
    988 MAY 1948
    989 MAY 1948

    Locomotives 970, 976, 979, 981, 984, & 986 were rebuilt with piston valves.

    In looking at the picture of the 989, Mantua came across my mind for an HO model. The 0-8-0 boiler is about right. Changes would include the stack, sand dome, pump location, running boards and finally you would need a Mellor cab. The drive could be the Mantua 2-8-2 Camelback. You can install the Alligator Crosshead and have the proper valve gear set up with the correct simplistic steam chest. It would be an interesting build and has peaked my interest.

    Sorry for the hijack. Back to the topic of the 989 on 1/2 scale.

    Thanks for the info, Karl! I wonder if you might know what the diameter of these boilers would be? I'm a steam enthusiast but really have no clue where I can go about finding this particular information. I was jotting down notes on the various details on the two engines and honestly have no clue what all these parts are called (let alone what they do!). I'm sure a locomotive cyclopedia would probably help me, but I don't know if I'd be able to identify the make of the injectors on these things, etc... I definitely plan on modeling the wood water barrel and ladle on the pilot, though! :) I won't be making the detail parts TO SCALE, but I plan on making parts that resemble the real thing... After all I'm sort of going semi-scale anyway (driver diameters are off by a little bit, etc)

    These diagrams will answer your questions.

    Excellent information! I love it. The 989 is slated to be built on my road. The drawings will help tremendously. Thank you!

    Mike,
    Are you using commercially available castings?

    Sorry for the delay. I lost steam on this project, unfortunately. My castings are in New York in storage... I'm excited to start a new employment opportunity in St. Louis shortly (pending background checks and all that hub bub). That will help bring my stuff home :)

    Darren, I am using the Little Engines 0-4-0, converted to a 2-8-0. The drivers are already done, the cylinders are mostly done (just need to tap the valve deck), etc... Then it's onto the running gear.
