Re: Icing in general

Time intervals could be specified under the tariff. I don't know the relative proportion of the various options in actual use. Tony Thompson

Re: Icing in general
Aley, Jeff A
To add a little bit of detail to Tony’s comment (that the Shipper got to choose), a UP Freight Conductor’s book noted the following different icing instructions for cars in the train (Roseville Fruit, departing Rawlins, WY on 10/13/1938):
Standard Ventilation = no ice, hatches open/closed based upon ambient temperatures.
Vents Closed to Destination = no ice, hatches closed.
Do Not Re-ice = iced initially, but no ice added enroute.
Re-Ice at _____ = re-iced only at specific location(s).
Standard Refrigeration = re-iced at all regular icing stations.
Std. Refrig with 12% salt = re-iced with 12% salt at all regular icing stations
One car was noted as having Std. Ventilation to Laramie, then Std. Refrigeration.
I notice that quantity of ice is not specified, which is consistent with Tony’s comment that they filled the bunkers. I also notice that durations (time) are not specified; only locations (regular icing stations or specific icing stations). Perhaps the duration info was translated into location for the benefit of the conductor.
The above data is from a presentation given by Mark Amfahr at the UPHS convention in 2013.
Regards,
-Jeff

This was decided by the shipper. Normally 24 hours would be selected, but in cool weather a shipper could choose a longer interval (or could specify the icing stations used). In hot weather, they could specify shorter times. They could even choose to let the railroad make sure ice was "sufficient," but railroads hated that because they were then easily the victims of damage claims. I'm sure local agents worked hard to talk shippers out of that option.

Re: Reefers: Heaters
Nelson Moyer
I was just reporting what I read. You didn't mention which railroad(s). Maybe some converted sooner? Weren't ice reefers about phased out by the early 1970. I think I read that the last icing platform was owned by PFE, and it was closed in either 1974 or 1976. Many roads switched to mechanical reefers earlier than that. I guess all the heater discussion is purely academic, since we don't model heaters or heater service.

Preco Mechanical Icing Machine
This week I discovered that Preco made mechanical icing machines, as evidenced by the label on the machine in the photo: The Link Belt Company also made mechanical icing machines and related systems. Unfortunately, when I contacted Link Belt, nobody knew that they had once been in that business and no material was available. Does anyone know if there were other major players in the mechanical icing machine business? Thanks. Bob Chaparro Hemet, CA

Re: Icing Reefers In Maine
Totally agree but the shippers and USDA were still testing methods in that era. I think (but have no documentation) that the shippers were going on the cheap for the first 24 hours of the trip, hoping the blocks would work just well enough while allowing them to avoid carrier icing charges.

Re: Icing Reefers In Maine
"...The method is to fill the bunkers with block ice corded or laid in such manner as to form practically a solid mass. In this way it is possible to place 15,000 to 16,000 pounds of block ice in bunkers of refrigerator cars which have a rated capacity of 11,000 pounds of chunk ice." (USDA)
I didn't know this. Looks like that's what they were doing in the photo. Thanks. Robert Simpson

Re: Reefers: Heaters
There are Jack Delano photos showing the older, larger charcoal heaters being lowered into cars in 1943. The newer alcohol heaters were smaller and required less work to load. Below are some photos from my collection.

Bending curved grab irons - Kadee pliers
Jim King
I use Kadee’s coupler trip pin pliers to create various round shapes in HO, S and O. While the various steps don’t equate to an exact radius, it gets me close so that minor adjustment finishes the part.

Re: Bending custom grab irons
Peter Ness
Jake,
I have a good supply of curved grabs these days, but in the past I have used a dowel (1/2” or less) or coin (quarter) and wrapped a length of wire. Once the wire is curved, even if the radius is not correct as needed, it can be formed to the correct radius. Bend the legs 90° to the curve an done. To be sure you get 90° legs, place the curved section on the corner of a flat box top with the legs sticking out over the edges on either side of the corner. Tape the curved part down if you need to. Bend the legs down on the box sides. Done.

Re: Icing Reefers In Maine

Jim: Fascinating bit of research on your part. Thank you for sharing. On the Penobscot and even on Moosehead Lake, log drives continued until the 1970's, and the bark and other debris had long turned the river water "pea green". It has taken until the current decade to start seeing historic game fish back in the river. I should add, there is a small business in harvesting extra-large logs from ancient days, still submerged in the waters. I don't know of any remains from ice houses on the shores. Many were leveled by fires, as one newspaper reported, "reducing the building and its ice to ashes". Anyway, the ice discussion is fascinating, whether it was potable or portable! -Dick

Richard, in my research reefers, reefer traffic, and on icing of reefers, and more to the point currently, of ice collection, there were two different types of ice "Potable" and "otherwise". Potable, which is another way of saying "Safe to drink". I am not sure the exact date this started however in my research, I can rather easily find records back to the 1910's that show that water was being tested. Ice cooling the drinks in the dining cars WAS subject to all of the state, local, and federal laws just the same as the water that came out of the tap of domestic houses. Clear Lake, White Bear Lake, and Detroit (now Detroit Lakes) MN, and additionally there were lakes in the more elevated areas of the Rockies and Cascades along the Northern Pacific like Thorp, WA. that were listed as areas of potable ice up to the 1930's. However not so much after that. In Northern Pacific archives exist records that these waters from which ice was melted were regularly tested to ensure they were safe for human consumption. Of the "otherwise" ice, ice that goes into a bunker never touches the cargo. A doodie in the ice would go down the ice bunker drain, like Bill says " It's no big deal". https://www.youtube.com/watch?v=TPxiXGr9nFM Of ice used as top icing, that I cannot answer - as I have never gave it to much thought regarding modeling. I would imagine (and beyond that have would have to get the desire to research it) however would imagine that anything that touched food for human consumption would be checked for cleanliness. The interest in clean water, clean ice, (germaphobia) was pretty well roaring in the 1900's. Subway tile could be argued is a by-product of this early fervor. Of mechanical ice railway plants, I think that has been addressed here before. Not common however not unknown by the 1900's. By the 1910's and 1920's articles in Railway Age can be found for mechanically produced ice factories that railroads were installing which produced in the tens of thousands of tons daily.

Re: Reefers: Heaters
Nelson Moyer
According to Jeff Wilson's book, "Produce Traffic and Trains", charcoal heaters were replaced with alcohol heaters in the 1940. Alcohol heaters were thermostatically controlled and had a pilot light, so that it was not necessary to remove and replace them with temperature variations as with the older charcoal heaters. From photos In the book, it looks like the alcohol heaters were smaller and lighter than charcoal heaters. A side bar on alcohol heaters shows a photo of the Preco version of an alcohol heater.
