Re: Removing mold from a railroad print
Thanks Schuyler, I'll try to find some. I tried the alcohol and peroxide on a que tip and nothing. I'm very disappointed but it is a print and I may try to find a new one. If available and affordable. In the mean time I may go try the alcohol again but, this time in a glass over ice. Fenton PS if anyone knows a good source of Howard Fogg prints, let me know.

Re: Removing mold from a railroad print
Schuyler Larrabee
Hi Fenton.
There is a process called “de-acidification.” As many of you know, the “Official Guide” book were printed on flimsy paper which was also acid-rich, and as a consequence become extremely fragile. I have an Official Guide from 1948, when I was born, and was interested in preserving it. The conservator I consulted told me about this process, which in that case involved inserting a thin deacidifying paper between every two pages – at some significant expense. As a result, my OG continues to deteriorate.
But with a single print, it might not be too terribly expensive. The questions asked about whether it’s a signed original print vs a reproduction are considerations for sure.

Looks like I was wrong and it is not mildew but an acid from the tube that it was stored in. It's brown. The freezer and drying it didn't budge it. NOt sure it's worth going too much farther. Anyone know a good source for Howard Fogg railroad prints? Fenton

Re: Removing mold from a railroad print

The brown "stain" on a print can also come from inadequate rinsing during processing. The pattern of the area would likely reveal whether it's that or acid from the tube.
As far as removing mold from prints: I have been happy with using 99% isopropyl alcohol on FILM. I soak a micro-fiber cloth in the alcohol, and rub the film well. Then I rinse using alcohol from a wash bottle. Let dry. Because it has worked so well on negatives (and slides), I'd try using it on prints. But testing carefully, at first--perhaps on a border.

Not sure it's worth going too much farther. Anyone know a good source for Howard Fogg railroad prints?" Time to step back and answer a few questions: 1. Is this a numbered and signed print? If it's a low numbered, signed print of a popular subject, it might be worth investigatigating restoration. 2. If it isn't numbered and signed, you might be able to get another copy at a reasonable price. Check eBay to get an idea of the market - a search on "Howard Fogg" returned 310 hits. Ben Hom

Re: Removing mold from a railroad print
I like Jon's idea Real photo paper is pretty water resistant. I would add a tiny drop of ammonia to the Q tip + water to kill the bacteria. but i'd test it first.

MEK and acetone are chemically very similar (both are ketones), but MEK has a higher boiling point. That gives you more working time: handy in warm weather.

Re: Removing mold from a railroad print
Michael Gross
The American Institute for Conservation https://www.culturalheritage.org may be able to help you find a paper conservator in your area. Naturally, there is some cost involved, and you will have to weigh the cost of conservation with the value of the print itself. I.e., is it "worth saving?"
Many conservators have sub specialties: works on canvas, works on paper, etc. Good luck! Michael Gross Pasadena, CA

Re: Susquehanna 40’ boxcars c1940-48
Schleigh Mike
Hello John and FC Group! The ERIE's 93000 series of nominal 36' inside length XM boxcars are of no relationship to the older 'Fowler' ERIE cars. The former were built in 1920-21 by Standard Steel Car. The Fowlers 1913-14 by both SSC and AC&F. None of the 93000 were a part of the NYS&W fleet. Mike Schleigh in Grove City, Penna.

The Accurail car is numbered 87134 - i.e., out of the second group. Their NYS&W 36' car is numbered 1567. I guess that January 1948 ORER I bought came in handy after all. -- John

Re: 3/4 improved dreadnaught endo for a 10'-0" IH boxcar

Fenton--Also the Branchline Rib/3/4 end can be modified. Sand or file the rib off flush then trim to the correct height. For me, the BL end looks better with its rounded contours. The ribs of the IM end resemble gear teeth.

I agree with Bob. That’s a job for professionals, or at least, professional advice.
I presume, Fenton, that the photo depicts a steam era freight car, at least?

This is kinda off topic but I have a railroad print that I forgot I had and after 6 or 7 moves I found it in a tube and it has some light brown mold on it. Does anoyoone know how to remove the mold without hurting the print.

Re: Susquehanna 40’ boxcars c1940-48
As a follow-up, I model c-1955 so I have a detailed NYS&W freight roster for that time period (1954-1958) with notes. The notes indicate that Suzy Q originally had 500 Fowler box cars listed as manufactured by Fowler Car Co. of Canada (could be a mistake). I have notes on the other boxcars that I thought you might find interesting, so I have uploaded the roster to the files here.
