On my layout (with a two-car deck), I usually tell operators to allow 15 minutes to ice a car.<br />Tony ThompsonTony Thompsonhttps://www.blogger.com/profile/11593061828601275378noreply@blogger.comtag:blogger.com,1999:blog-3218524178230712938.post-17591949174786876232021-12-16T14:29:13.074-08:002021-12-16T14:29:13.074-08:00WOW that's quick!

I'd have thought it would have taken much longer, what with such massive blocks needing to be broken up, slid around, etc. I have a small two-car-length icing platform in an industrial district that will see fairly regular service from a local shifter pre-iceing cars, though mostly initial-iceing loaded cars. I wasn't sure how to direct the switch crew but now I have a much better idea. Spot the reefers first, take care of any other business, then pull the iced cars before heading out. Fortunately for the crew there's a good place to wet their whistle just next to the ice plant if they need to wait.<br /><br />Thanks for the helpful reply.<br /><br />GalenGalen Gallimorehttps://www.blogger.com/profile/10272822237546731134noreply@blogger.comtag:blogger.com,1999:blog-3218524178230712938.post-30438924085238054512021-12-10T11:35:40.116-08:002021-12-10T11:35:40.116-08:00Galen, it was minutes per bunker with a crew worki...Galen, it was minutes per bunker with a crew working full tilt, at most 5 minutes. Of course there were crews at both ends of the car, and multiple crews working along the ice deck at the same time. PFE data showed that the average for a full train was one minute a car, 90 minutes for a 90-car train, of course reflecting the multiple crews.<br />Tony ThompsonTony Thompsonhttps://www.blogger.com/profile/11593061828601275378noreply@blogger.comtag:blogger.com,1999:blog-3218524178230712938.post-6312216901461651322021-12-10T09:16:27.211-08:002021-12-10T09:16:27.211-08:00Tony,

After 1972, the tariff no longer included ice refrigeration, so there would be no ice in bunkers of ice cars. Re-top-icing remained in the tariff for some time, but I don't know when it may have left the tariff, if it was removed.<br /><br />Top icing melons seems relatively ineffective. Top icing had its biggest value with leafy vegetables, for which it helped keep them moist as well as cool. It would accomplish relatively little in pre-cooling of a dense, convex item like a melon. But shippers did not always do the most rational things in deciding how to move their cargo.<br />Tony ThompsonTony Thompsonhttps://www.blogger.com/profile/11593061828601275378noreply@blogger.comtag:blogger.com,1999:blog-3218524178230712938.post-82007232432368224372013-02-28T01:11:38.499-08:002013-02-28T01:11:38.499-08:00Top icing occurred well into the '90s on the W...Top icing occurred well into the '90s on the Westside. I saw many a carload of melons getting an application of ice as they were being loaded. The melons were contained in wax boxes, and shaved ice "snow" was blown into the boxes to cool them down. The pallets of melons were then loaded into the reefers, and more "snow" was blown in once a row was loaded. <br /><br />I doubt that any further icing took place, as this was probably an initial cooling (pre-cooling) for the produce.Smokey Behrhttps://www.blogger.com/profile/08691420527819467913noreply@blogger.comtag:blogger.com,1999:blog-3218524178230712938.post-23243540999182998592012-12-07T16:56:45.391-08:002012-12-07T16:56:45.391-08:00Water from melting ice simply drained out of the c...Water from melting ice simply drained out of the car. There were drains above each truck sideframe (one at each car corner). The bottom of the bunker was only slightly below the car floor, so if water was retained in the car, it would soon have flooded into the load space. Many who saw ice reefers in service remember the draining water; there is a photo of this in the PFE book (2nd edition), page 391.<br />Tony ThompsonTony Thompsonhttps://www.blogger.com/profile/11593061828601275378noreply@blogger.comtag:blogger.com,1999:blog-3218524178230712938.post-47629850609790729192012-12-07T16:51:27.839-08:002012-12-07T16:51:27.839-08:00Interesting, as usual.

Were there drains in the car, was it allowed to leak out, or was it allowed to accumulate in the bottom of the cars?John Tottenhttps://www.blogger.com/profile/16518369473058182505noreply@blogger.com
