An old-style ice reefer had hatches on either end of the roof, into which workers would load ice. What was the inside of the car like? Was each end simply an ice bunker, completely isolated from the rest of car? And, did the workers go inside the car, either through the side doors or through the roof, to arrange and re-distribute the ice blocks? I assume there was some sort of convection-driven air circulation system to distribute the cold air, but what did that look like?
Yes it was a bunker at each end. If I am not mistaken a fan recirculated the air over the ice and of course it had to be refilled if a long trip. They also had a kersosene heater for winter operations.
There were quite a few types over the years before the mechanical refrigeration units showed up. There were end bunkers, top hung ice trays, brine solutions for lower temperatures, lots of different manufacturers, etc. Some were natural airflow, some were fan forced.
There was a good series of articles called “The Postwar Refrigerator Car–A Brief History” published in Railroad Model Craftsman magazine, March, April, and May 1994 issues. Although the title says “brief” and postwar," they do go back into the prewar history, and cover the types in detail. I don’t know Carsten’s Publications availability of back issues, but you can usually find them on Ebay.
I’ve had an ongoing discussion about reefers with a guy at work who used to watch them loading ice across the lake from his childhood home. He thinks that the crew actually went into the car to arrange the ice, while it looks to me that those hatches were not designed for access on a regular basis. Can anyone shed any light on this question?
It depends on what part of the car they were going into, according to him. The type with the hanging ice bin would have to have people push the ice to the center of the bin. They most likely entered thru the ice hatches.
Also, there were cars used to transport ice, especially before they had mechanical refrigeration to make the ice at the ice houses. The ice would be collected from ponds and lakes and stored in the winter. Since not all reicing platforms were near ponds or lakes, they had to ship it to these houses. But the article implies this was quite a while ago, probably before his time.
Close the door and the light stays ON!
Never mind…[:)]
Some icing facilities had essentially a big hose that they could shoot crushed ice over the items being carried inside the car. I would assume that the workers would enter thru the side door. A man could go down into the bunkers thru the roof hatches, but the hatches were primarily there for loading ice blocks into.
The ice would be loaded into the bunkers and cool air circulated by convection. After a bit somebody figured that it provided better cooling to use circulating fans run by belts off of the wheel axles. The waybill for icing would would specify the re-icing location and the amount of rock salt to be added w/ the ice (the faster the salt caused the ice to melt, the colder the car got). The ice blown in on top of the load was called “top icing”. Can’t argue w/ that logic!
Some produce didn’t need to be iced, but needed ventilation. The car’s ice hatches could be left open partway to allow fresh air to blow thru the car, and to keep the heat from building up inside.
Hi Tom,
I sort of feel someone was putting you on. The bit about collecting ice from ponds I mean. We have had ice in Australia for a long time and the ponds and lakes never freeze over. I do not know how they did it, but they could make ice before they had mechanical refirgerators.
I remember at my grandmother’s she had an ice box and the “ice man” would deliver blocks of ice to put in the box. That was before she had a refrigerator. However, I have to admit other people would have had refrigerators by then.
Someone who knows about ice can possibly enligten us how ice was made before the era of mechanical refrigeration.[?]

The process is documented in publications like White’s “Great Yellow Fleet”, and articles that have appeared in RMC and some specific railroad’s historical society journals. Cheers, Mark.
Mark,
I thought perhaps it was not beyond the bounds of possibility. However, that would be a seasonal thing, and more or less a bonus. They must have had a way to make ice in the summer. I wonder how it was done.
Moreover we had a van, I think its code was MRC, that was a similar principal to US reefers. It was wooden “matchboard” construction so must go back a few years. Where did they get the ice from for that?
Not “putting me on” but going back in history quite a ways. We have an old restored ice house in Tobyhanna PA (near Scranton) where they reenact the gathering of ice from the pond, usually in January or February each year.

And funnily enough, an Australian was a major player in its development. James Harrison, who had emigrated from Scotland, developed what was known as the vapour compression system. This and other methods were used to manufacture ice commercially. <“Moreover we had a van, I think its code was MRC, that was a similar principal to US reefers. It was wooden “matchboard” construction so must go back a few years.”> They do go back - many were built by Ritchie Bros, Tullochs and Meadowbank Manufacturing. MRCs and the other refrigerator vans of the NSWGR all owed their design to the Tiffany car imported during the 1880s. Instead of end bunkers typical of modern US practice, MRCs had overhead, or roof bunkers. Canadian reefers also used this design. It was felt by some authorities that roof bunkers were more efficient than end bunkers. <“Where did they get the ice from for that?”> Again, refrigeration plants. Both Peters - The “Glacerium” - and Dairy Farmers plants at Darling Harbour yard had ice-making facilities. Elsewere in Sydney there were ice plants at Pippita and Yennora. Likewise the various dairies, abattoirs and cold stores around the state all supplied ice for refrigerator vans. Cheers, Mark.
The road that I live on was originally an indian trail, then when the settlers came, the trails usually became the roads. We live about 100 ft above a river which used to have grist mills, tanneries, foundries and anything else that could make use of the water power. And, in the winter they used to cut ice from the river. A friend down the road actually had an old ice house on his property, midway up the hill between the river and his house. Up on the main road there was a larger ice house which apparently sold to the general public. I seem to recall reading that the blocks of ice were packed in saw dust to slow the melting in the summer months. Ice harvesting and distribution was a pretty busy industry in some rural areas.

Question about, “how did they make ice before refrigeration?”
Think of the “evolution” of mechanical refrigeration in three stages.
First commercial mechanical refrigeration with ammonia and the like, requiring a large plant and control by engineers, complicated process, large scale, not automated. I don’t know whether or not there was mechnical refrigeration of some sort powered by steam, water power, etc, before efficient electric motors came along in late 1870s, early 1880s, the same time that electric street railways flourished. This is the time when ice made in an ice plant would be delivered to homes for “ice boxes.” I also know of refrigeration of some sort in steamships built before World War I. That again was large scale and in an application where there could be an engineer of some sort to keepmit going.
Second stage, home-size electrically powered refrigeration, more or less self-contained. Plug 'em in and defrost them once in a while. I know these were available in the 1920s from old electric company brochures. This technology depends on two factors- the development of the home refrigeration appliance itself, AND the wide availability of electric service in cities.
Third stage, mobile refrigeration units built reliable enough to take the punishment of operating in a moving railroad car. Into general use in 1950s. (some limited earlier use…)
Speaking strictly from my take on ancient photos and drawings, and my personal experience in the colder states of the US:
Before mechanical refrigeration - even before railroads - ice would be harvested from frozen ponds and lakes when the ambient temperature was well below freezing. The workers used the kind and size of saws used in modern single-bucking contests at timber sports competitions. The blocks would be handled like logs, floated to a ramp, skidded ashore and piled up for storage in ice houses, which were large structures with thick walls filled with sawdust. Since a hard-frozen pond could easily have ice two feet thick, blocks as big as 2x2x6 feet were not uncommon.
Harvesting would continue until the ice houses couldn’t hold any more. Ice would then be removed and sold to whoever wanted it for whatever purpose. There are records of ice from Wisconsin and Minnesota being shipped down the Mississippi in steamboats so southern planters could prepare ice cream and mint juleps for their summer garden parties.
Usually, just about the time that the last few chunks of ice were melting away in the ice house, returning cold weather would once again freeze the ponds and the cycle would begin again.
During the “back to nature” movement a few years ago, some intrepid soul tried to build a “natural” ice box for his log cabin in the woods, harvesting ice from the pond behind his domicile. He ended up with a box smaller than most domestic refrigerators surrounded by an ice room almost as big as the rest of his cabin - and still couldn’t keep the milk from going sour.

Heaters were placed in reefers to prevent the contents from getting too cold. (Would you want your shipment of California oranges to freeze on its way to Chicago during the winter?)

I recall Thomas Jefferson’s Monticello had Ice Rooms where they put ice during the winter insulated with sawdust or straw. Then I think they used to surprise the guests with drinks that had ice in them in the middle of the summer.
I am not certifying this tidbit because I was a child when I heard this story during a tour of that Estate.
Thanks to all for broadening my education. Especially Kenneth L. Anthony aka “leighant”. I appreciated that succint explanation of the phases of development of ice making. I had a look in your profile Kenneth and found out that your profession is teaching history. Thanks for sharing some knowledge.
I know nothng about ice making, but appreciate the efforts of those who developed the industry especially so that we can have a cold beer on a hot day.[:D]
