EMD GP9 1:48 Scale

Shawn Branstetter's picture

I'm not sure if I took on more than my skills will allow, however, this is my next large project; and EMD GP9 Phase I. This build will be totally freelanced for my railroad set in 1974. I am planning on only having one on my railroad unless I find that it is easier to build than first thought. 

The plan is as follows:

  1. Scale underframe - The entire underfame will be built per prototype photos using sheet and strip styrene. As much pipe and electrical detail (that I can find) will be included. 
  2. Battery powered - My plan is to battery power all my head-units so I do not have to wire a layout. I will be using the North West Short Line Stanton unit which is a remote control DCC set up. This will include sound.
  3. Motors - As of now, my plan is to use the North West Short Line, Magic Carpet drives, one for each axel, as the prototype. 
  4. Full cab interior.
  5. Lastly, I will be scratchbuilding all exterior grills.

I will be very interested to read up on your experiences with using the Magic Carpet drives. I've followed Brian Strom's work here: http://www.paducahbuilt.com/index/OscaleP48/O_PaducahProject and have been very intrigued to tackle one of these as I switch to P:48 myself

I'm curious as well. I've been following his post as well as spoke with others on the P48 Yahoo! group and there are very differing opinions. First and foremost is power. My railroad will only be running between 2 or 3 cars at a time so I don't think that will play a big factor. The other is noise. Older drives were loud but I'm hearing that the newer ones run much quieter.

Work has started on the underframe. The center channel will be filled with lead and then covered with styrene. Additional weight will be added to the top of the frame under each truck.

I was not happy with the previous underframe so I decided to rebuild it as seen in this photo compared to the previous one. I have also began adding some weight to the underside. These will be completely hidden with styrene as soon as it is glued in place. Additional weight will be added inside both hoods under the trucks.

Shaun; what happened with this build. Seems to have gone off the rails there somewhere. I'd be interested in finding out more. In the (very long) middle of rebuilding 2 x Weaver GP38-2s to a more accurate version of themselves.

Yours sincerely

You are right! I started working on an HOn30 micro layout for my boys which has taken up all of my modeling time. The boys are losing interest and so I am probably going to turn my attention back to this project. That said, I purchased a steel frame for the Red Caboose GP9 from FineScale 360. It adds much needed weight to the model. I will then wrap styrene details around it in order to detail the underframe.

I'm finally back at the workbench with this. I purchased a steel frame from FineScale 360 which adds a good bit of weight to the model. I also used lead fishing weights in the equipment boxes for additional weight. This was secured with CA glue and covered with modeling clay.

Using a carving bit in my Dremel I can carve the thick plastic walls to look like the prototype sheet metal skirts. I'll then go in with jewelers files and clean up the area.
Not to bad!

The frame is steel from FineScale 360. I had the owner cut the sides down so I could detail the frame. I'm using styrene to build up the prototype frame details. Other than that, the blue frame is from Red Caboose with some of the skirt removed to reveal the details.
