The IC had a huge fleet of such cars -- originally 1,500 cars ! series 32000-32499 (1940 ? ) -- 488 cars in 1950 series 33000-33999 (1941 ACF) -- 984 cars in 1950 134 of the 984 cars in

The Soo Line (actually, Wisconsin Central) also bought a small group from Pullman, fifty cars numbered 136200-136298, in 1936; 50'-0" IL, 10'-0" IH, with six foot flat steel doors. I don't know what

IF I chose to make my own plugs, gluing the bolster back together would have been fine. You still can't tap FUD. I chose to add a sprue with some plugs and have the part printed again. At $12 a copy,

Clark, I know of two smaller Southeastern railroads such as Western Railway of Alabama which also rostered 50' steel boxcars with 6' wide door openings and were of 10' interior height numbered in the

Tony, Did the NWP overnight cars originate in San Francisco or Tiburon. If the former, they would have most likely made that journey across the bay on the Santa Fe's Navy. Sort of but not really

This has reminded me of a 3d printed object I got some 10-15 years ago. It was a lightweight near-black print of a hand calculator with details to the print. It was a commercial 3d printer sample. I

Thanks for chiming in Dennis. I recently had Shapeways print some passenger truck sideframes in wax that I drew up for Rio Grande Models (Valley Brass & Bronze did the lost wax process) and I had

We’ve been curious about the purpose of making 50’ steel box cars with 6’doors. The C&NW and Milwaukee had this design. Both served the UpperMidwest. We were think of a light, but bulky lading

Tony I mentioned that particular small narrow part because that is exactlywhat was part of Jack's model. He had some difficulty in getting the part madecorrectly and other such parts (handrails,

No, 3D models are not "flimsy". I have passed around the frame for the side dump I'm working on at a number of clinics and no one has broken it yet. Thin parts are brittle and you need to just be

For freight and passenger cars, I don't see FDM printers ever getting to the quality we require, but they can be used for structures, when the structure can be designed correctly to fit the printer.

Tony All of the methods use some kind of heat-sintering to join beads ofmaterial together. As a physicist and mechanical engineer can you tell me thatthose kinds of mechanical bonds are as strong as

While this comment may be true for many HO and larger bodies it is not so for N Scale. While we would certainly like to get better materials and resolution there are many very credible printed model

If you don’t mind putting on your own rivet/NBW detail, wire steps, grab irons and ladders, the extrusion made models are just fine. Like the real thing, you’ll need to put on stand alone brake
