example, builders photographs from Alco Historic Photos. Contact prints made from historic 8x10 negatives have detail that is amazing even under a high powered loupe magnifier. On the other hand some of the silver halide freight car prints that I have purchased over the years are disappointing. Many are still "the only thing out there" on those cars, though, so the prints can be quite valuable for freight car research despite the quality. Either approach - silver halide or digital - can give good results in the right hands. The right originals of old images are important in either case - good full-range negatives that were well focused and properly exposed and developed, instead of poor "thin" copy negatives. I used to use Kodak Technical Pan film to make copy negatives of historic black and white freight car photos. The negatives were great, but often it was a challenge to control tonality in printing. Reflections on the originals also presented challenges, even with polarized light. It is much easier to copy prints with a digital flatbed scanner. The digital scan generally gives you far greater ability to pull out shadow detail on freigh car underbodies when copying prints that have "blocked-up" shadows than does copying onto film. Scanning from negatives is always preferred over scanning from a print; the print always has less range than the negative unless made by an exceptionally skilled printer. Also, I second Tony Thompson's remarks that paper and chemical supplies for silver halide photography will continue to be available for many years. Rufus Cone Bozeman, MT Rob Kirkham wrote:

I take your points Rufus, My comment arises from my experience with prints - and scanning them at very high resolution to identify tiny details in the background - often freight cars in a yard of interest. I have found that a 30 or 50 year old black and white print will provide a lot more information when blown up that way than will the typical 8x10 print I buy from the local archives. I suspect that is simply because they scan at 300 dpi, and it isn't sufficient for those tiny details....

process print is _not necessarily_ lost in a digital print. Quite the contrary, even if you have middle range equipment. With Photoshop or lower priced image processing, you can "bring up the shadows" by manipulating "curves" or using "shadow/highlight" commands, revealing shadow detail that would be lost to all chemical darkroom printers except the most skilled and dedicated. This can give spectacular improvement in underbody detail, hopper end detail, etc. It is widely accepted among very critical fine art photographers that even if they still shoot negatives or transparencies, color or black and white, and even if they are still using 4x5 cameras for image capture, that they should scan their negatives or transparencies and print them digitally. Fine art digital printing has surpassed the quality of silver halide printing except for very specialized situations. Fine art digital prints are concerned with the rendering of detail and smooth tonal variation that we have associated with silver halid photography. Digital printers that are far less expensive than a brass locomotive are capable of exceptional quality. Assuming you already have image processing software for your digital camera, you can get a scanner and printer capable of this competitive quality for less that $1000 total for both (not each). To keep this discussion on track with freight cars, it is worthwhile to point out that many railway historical societies are producing CD's of scanned photographs. NPRHA is an example http://www1.storehost.com/stores/xq/xfm/store_id.615/page_id.23/Item_ID.134651/parent_ids.0,0,11/qx/store.htm http://www1.storehost.com/stores/xq/xfm/store_id.615/page_id.23/Item_ID.151419/parent_ids.0,0,11/qx/store.htm I make these judgements after long personal experience with traditional silver halide photography. The customers of Jack's high end lab would not accept the change to digital if improved quality were not provided by that lab after the change. They have to face their own commercial customers who demand the best. Rufus Cone Bozeman, MT Rob Kirkham wrote:

I do not believe that either. How many 10s of thousand mold makers are there in this world. One could not stop the project> If one wont do it then find a second or third. The person doing the project is at fault.

Hey,
Does anyone have photos of the idler cars used by the Santa Fe at Ferry Point, Richmond, CA? I have seen the Ft-N photo in the SF MOW book, but I am not sure that these cars were used there in the early 50's era. Any help will be greatly appreciated. Rick Dietrichson Wilmington, NC

For example, it is still possible to buy everything you need to set metal type and hand-print it--though it's not remotely commercial. It's just become a specialty market for a very few hobbyists. I strongly suspect the same will be true for "silver halide" photography throughout the lifetime of anyone on this list. But as Jon says, of course at SOME TIME it will go.

another source of scale scrap
James Mischke <jmischke@...>
I have been progressing through a trio of Speedwitch Duryea
underframes for Red Caboose boxcars as B&O class M-26d. Doing things in threes means either I learn from mistakes on the first one, or make three consecutive mistakes for fleet uniformity. My beedy eyes noticed that the resin flash between parts is perfect sheet metal scrap. Thin. Stiff. Flat. Holds paint. Does not cut flesh unless provoked. The first 1000 rectangular shards were done by hand on a block of wood with an exacto blade. Then I remembered I had a Northwest Shortline "Chopper" and made a billion more. I tried to keep the size down to two-three scale feet in any dimension, processed scrap needs to fit into the furnace mouth. I made some attempt at orthagonality, but not always. I hope someone finds this idea inspiring.
