Welcome to Our forum Josh!! and I'm sorry but I don't know of any of the Flat Models your looking for but some body here may know. If your thinking scratch building you may want to just find a Box car long enough to use as a kit bash base. Basically alot of box cars start out as a flats until the box is attached.

Anyway welcome and hope to see photos of your projects.

Check the index of the SP Historical Society's, Trainline magazine for the past few years.  There is a very good article about building them from styrene.

Thanks for the welcome!  If I ever get the dimension for these cars, I might even build one in S or O scale just for kicks.  Dan, starting with a boxcar is an idea I hadn't considered.  I wonder if there is a boxcar underframe that looks like these flats. 

Steamage, thanks for the recommendation of that SP Historical Society publication.  I checked the contents of their back issues and figured that the bulkhead flatcar project must have been listed as one of Tony Thompson's regular "Modelling the Southern Pacific" features.  Do you know which issue that was? 

Josh, yep, that's a good name!  I've got a lot more ideas floating around right now than completed scratchbuilding projects.  The few structures and rolling stock I've attempted have been wood, and I'm trying to learn to work with styrene now. 

The article is in issue 97 of the society's Trainlines: "How to model a 1960s MUG train."

(MUG means "Empty Eugene.")

Thanks, Mark.  I see that back issue is still available! 

This is what I'm after.

I'm not sure what the guy that built these used to begin with, or if he made them from scratch, but they look dandy. 

I've gotten frustrated trying to find a suitable flatcar to start from, so I thought, 'Heck, I'll scratchbuild the sucker!' This is more of a quick and rough "learn to build with styrene" project than it is a quest for a museum quality model, which it ain't gonna be.  I used Evergreen 4080 sheet for the deck, and the rest is cut from 0.030 smooth sheet from Evergreen. Trucks will be Kadee 518s. I have a lot more to do on the car, namely the webbing on the bulkhead girders, the underframe, the stake pockets, and the draft boxes. If I get that far, I'm gonna hafta learn how to paint! This car represents the Southern Pacific F70-50, F70-59, or F70-61 classes. I chose to make this one with steel plate on the bulkhead faces instead of boards.  Any suggestions for material for stake pockets would be welcome.  I'm thinking some small C channel. 

Josh,

Great project!.  I really love the slightly curved look of the uprights on the 40 series cars - perhaps that can be your next one.  For channel pockets I'd agree on the C channel.  It will be easier to cut to length and use, and will give you open pockets.

Now once you are done, make a nice mold of the sucker in RTV, and cast it in resin.  I'm willing to be you'd have mor ethen a few customers here!
