Technical Drawing Source?

[Anonymous]

Greetings all,

I'm looking for technical drawings of locomotives, specifically the interior frames. Does anyone know of a good resource (free or fee) that has typical construction drawings for modern diesel-electric long-haul locomotives? All help appreciated...

Thanks,

SW

Have you tried going over to Google and simply indicating what you are looking for and see possibly you just might find it....

Tried that without much success. Any other suggestions anyone?

Thanks, SW

steelwater,

I'm not clear what you mean by "Interior frames".

Modern locomotives like the GE AC4400CW or the EMD SD70M are built on load carrying platforms, based on a pair of I beams running end to end inside the frame structure, with everything else hung from that. The cabs are constructed separately and added to the frame, sometimes with a flexible mounting. There are often beams added to the frame inside the nose to reinforce it to protect against collision or grade crossing accident.

The hood itself has little structure inside it, looking much like it does from the outside, remembering that much of the hood is removable doors and hatches.

Model Magazines, MR, RMC have external drawings, as does Withers "Diesel Era" magazine. The "Extra 2200 South" magazine has published drawngs showing the internal arrangements of locomotives, which would show some of the structure.

Manufacturers usually provide "Cutaway" drawings in their instruction manuals for locomotives showing the interior of locomotives, and you might be able to find these among railroad "collectibles" throuh the web or in museums and hobby stores. You might ask GE or EMD if they will sell you one!

Trade magazines like "Railway Gazette International" often provide "cutaway" drawings of locomotives when a new model is introduced.

If this hasn't covered what you are looking for, try to indicate what you specifically need and someone will know where to look!

Best of luck,

Peter

Peter, those are some pretty good leads actually, so thanks. The frame components you mentioned are more or less what I'm looking for info on: collision posts, anti-climbers, front plates, etc. I've found masses for major components, such as engines. These cutaway drawings would be good, but I'd also like to find cutaway or technical drawings with dimensions (at least nominal) for these major frame components.

You might also try the railroads themselves. They receive dwgs from the manufacturers with construction details for use in future wreck repair. Some will sell you a copy for a nominal fee.

I'll try that, Don. Thanks...
