    The cab design is taken from an A-6 "intruder" (Navy aircraft), with scoops under the nose. I found a nice drawing and started from there.

    Matching coach:

    My thought is to:

    • Mechanism: Kato "critter chassis"
    • Body: 1/2" thick blue foam
    • Spray paint it flat black
    • Print out and laminate the details on it.
    Yes, it will be "toy like". Works for me. :)

    I'd rather build them than draw them.:tb-biggrin:

    This was built as an April Fool's joke. It's two old Mehano FA-2s joined nose to nose, with the wiring reversed for one unit. The flanges are too large for C55 track; it was a monster puller on C80 track.

    Pete, always loved that one.
    It reminded me of this pair of Life Like FA2s back to back:[​IMG]

    FM H30-66

    Let's say that FM never gave up the locomotive business... they settled their squabbles and kept on going...

    Here's an H30-66, 3000 horsepower direct competition for the SD40.

    My design for a 2-10-0.

    Class name is SD, an acronym for "Standard Decapod."

    Yeah, I numbered it after North Carolina Transportation Museum's Russian Decapod.

    Here's the specifications... (Using short tons.)

    Tractive Effort: 70,805lb

    Driving Wheels: 60".

    Cylinders (2): 28 x 34".

    Boiler Pressure: 250psi.

    Locomotive Weight: 294,500lb (147.25t).

    Adhesive Weight: 270,000lb (135t).

    Valve Gear: Bakers, outside; left hand running.

    Grate Area: 55sq ft.

    Heating surface: 2,764sq ft.

    Superheater: 640sq ft.

    Tender Weight: 134,800lb (67.4t).

    Fuel (Coal): 26,000lb (13t).

    Water: 7,400 US gall.

    Engine + Tender Weight: 429,300lb (214.65t).

    Total Length: 82' 2".

    My design for an articulated locomotive.

    MCD is an acronym for "Mallet-Consolidation-Decapod."

    Yeah, I numbered it after NCTM's 2-8-0 that's being rebuilt.

    Here's the specifications... (Using short tons.)

    Note: The tender is the same "Centipede" model used on Union Pacific Big Boys/Challengers/FEF's.

    Tractive Effort (Compound): 135,165lb

    Tractive Effort (Simple): 179,300lb

    Driving Wheels: 52".

    Cylinders HP (2): 26 x 32".

    Cylinders LP (2): 30 x 32"

    Boiler Pressure: 290psi.

    Locomotive Weight: 705,900lb (352.95t).

    Adhesive Weight: 694,300lb (349.65t).

    Valve Gear: Bakers, outside; left hand running.

    Grate Area: 110sq ft.

    Heating surface: 5,964sq ft.

    Superheater: 2,052sq ft.

    Engine + Tender Weight: 1,133,400lb (566.7t).

    Total Length: 128' 7".

    Interesting concepts! The last one would probably require about 144" radius in N scale. Just joking.

    If you go to large view, you'll see that I labeled 3 drivers "flageless."

    That 2-8-10-0 is a real behemoth. It would look really impressive with a lot of pumps and other equipment hanging on the front of the boiler.

    Nice job!:thumbs_up:

    Like the Challenger, the MCD's pumps are under the headlight.

    If a 2-6-8-0 was built, this isn't unreasonable.

    I do have a plausibility quibble. A locomotive like this would probably have been built in the WW1 era, and the centipede tender wasn't introduced until 1941 to my knowledge. The 2-8-10-0 could have been refitted with such a tender late in its life, I suppose.

    You seem to have a taste for large power without trailing axles.

    Well, it's designed for drag frights. Slow speed needs tractive effort more than horse power, and the more adhesive weight, the better tractive effort. All and all, though, my mallet design is no larger than a Y6 2-8-8-2...just has another driving axle instead of trailing truck.

    I may consider having my designs for a fictional railway... :tb-biggrin:

    That's exactly it. Most railroads didn't buy new drag freight power in the late steam era. Because the average speed of freight trains went up between the 1920s and 1940s, there wasn't much need for more slow freight power, but for fast freight power - Berkshires, Challengers, etc.

    That's something I regret - that most North American railroads bought only fast freight and mainline passenger steam in the last generation. I generally like better to see purpose-built power for less glamorous duties, not downgraded older power. That's why I'm interested in the exceptions: CP branchline 4-6-2s, Reading commuter 4-6-2s, C&O 2-6-6-2s...

    Now, I'd like to see this with a cab in the center, and triple articulated, with overhead pntagraphs. Like the old MILW Bi-Polars. :rolleyes2:
    With a B-D-B truck arrangement. Keep standard truck on the ends, and put a 4 axle truck in the middle, with articulation points on either side of center truck.

    I don't have any drawings or pictures to provide, but My workbench currently has an Atlas/Roco GP40 which is going to be getting a bashed Saftey Cab on it.

    The trick is I want it to be a GP60M style cab. That's the cab style I like 2 teardrop windows full width.
    You can't buy a kit for that anymore, so I'm gonna bash it out of an Athearn SDF40 (or whatever they were called) Shell I got cheap and parts of a cannon 3 window SD60 cab.

    I also have ideas floating around in my head for Tier II engine rebuilds. Between what modern companies are doing with rebuilds and the old Alco with an EMD Prime mover rebuilds of the 60s and 70s, it's hard to come up with something unique, but it also makes this kind of thing very prototypical.

    I have one I designed for my HO Scale Layout. Now I do not know who the original drawing was by as I found it on Google Image Search and I cannot track the original drawing down anywhere online. I have since chopped the drawing up and modified it. If anyone knows who drew the original drawing, let me know so I can credit them please.

    But my design was "What if MPI's new cab locomotives were designed exactly like EMD's F Series:

    WolfcreekMPI.jpg

    Roof mounted Fans, Diaphragm in the back and a Dynamic Brake Fan. Other items being designed atm include a Canadian Pacific Style Winterization Hatch, and a matching Booster Unit. The Actual HO Model I will build will have cooling pipes, icicle breakers, etc. I love Cab units and I loved MPI's except for the lack of a diaphragm walkway. I'm a Cab Unit Purist.

    Another "what if" loco. EMD had its DD35 and DD40, GE the U50s, Alco even had the Century 855. So Fairbanks-Morse could have had this behemoth, H50-XX:

    The fuel tank's from an SD40-2. The rest is all FM.

    I could see that one in SP colors, like their Train Masters. And it would have made some nice music with those two big OPs in there. :D

    And this would be how long?:tb-biggrin: It looks longer than some of my ships!
