I'm building a CN GY-00m slug. They were rebuilt from ALCO S-3's in 1964/66, and multiple rebuildings, upgrades, and renumberings later, the ones that are left are in the 264-270 series.    |

My starting point is an Atlas S-3. Step 1 was tearing everything down and removing all driveline components, since I will be using it as a dummy.  Next was to remove most of the cast weight from the cab area, under the hood and the cast fuel tank. This was important to reduce the weight as much as possible so it's not a massive dead weight for the Geep that will tow it around.   Next up was starting to build up the body and some underbody detail. I just used plain styrene for the car body sides.  I made the air tank from a pen tube with some wire for the air pipes and some strip styrene for the hanger brackets.   |

Looks interesting what will you do for the flexi-coil trucks.

Next up was truck mods. You can see how the sideframes are attached to the bottom of the gearbox with pins on the sides, and screws on the ends.  I was lucky to find an old Athearn BB switcher at my LHS. This had been someone's project, but they gave up on it. Among parts they had added were Flexicoil trucks!  First step of trying to mount these to the Atlas truck was to remove the pickups from the Atlas sideframe. This was for 2 reasons: 1. I will still need electrical pickups to power lights and such. 2. It gave me something to attach the Athearn parts to.  Next was to mark and grind off some of the metal from the bottom plate to make it less visible behind the new sideframes, and also allow the new parts to sit at the right distance away from the wheels.  Here is the piece after some grinding and filing, with one of the pickup blocks attached.  I removed all the Athearn mounting hardware from the Flexicoils and sanded the backs down to thin them down a little.  After some test fitting and sanding, and being careful to make the bearings line up where they should, I glued the new sideframe to the pickup block and the bottom plate.   Here's how everything looked after completing both sides and putting the pickups back together. Essentially I re-created the Atlas truck, but with new sideframes.   The completed trucks  Here they are where they belong.  |

That's some nice hard-core modeling you've done there!

Awesome build! Did you check if there was enought room that maybe it could be powered Where did you get the dimensions for the hood?

Awesome build! Did you check if there was enought room that maybe it could be powered Where did you get the dimensions for the hood? Not sure if it there is enough room that it could be powered or not. The original drive train wouldn't have fit under the new hood. I never planned on having it powered in the first place so I honestly haven't put any thought into it. When I finish it, it will be used in local and yard service. Locals are about 6-8 cars on my layout so the Geep mother can easily drag it around. In yard service it will run with it's mother and perhaps one additional unit depending on the situation. But 2 Geeps, or a Geep and an SW, is plenty of power for yard moves on my layout even with the slug as a dead weight. The hood dimensions I basically guessed on, based on relative sizes of other parts of the unit, and comparing with photos. I did recently find this set of plans, though:  According to this my 'eye test' dimension for the width of the hood is bang on, so I imagine I did pretty well on the other parts as well. |

Great looking build. Any update? Still chipping away on it. I've been working on some other stuff lately so it's been a little while since I worked on it. |
