Re: 3:1 Reefer to Reefers to Boxcar ratio
Dan,Yes this is referring to the westbound movement. The eastbound movement was heavily loaded, however, keep in mind, some perishable from the Southeast, East and Northeast was moving westbound. Thus using the "total" to determine total eastbound/westbound movement does not give a complete picture.
No published source, yet. I've been spending a significant part of the past 10 years gathering the information about the ARA/ICC/AAR Car Service Division. I'm happy to quote specific information, but a complete rundown would exhaust the scope of the group. Much of the data has come from my years working in the industry and Car Service publications I saved while working.
None, except on Service Order 822 covering the loading to the Pacific Northwest area and this only covered from Sept 1, 1948 until June 30, 1949. After that date, the movement was covered under tariff and statistics were not kept for "all" 3:1 or 2:1 movements.
If the data in (1) is for WB reefers, and EB reefers were nearly 100% loaded through the same locations, then with only 25% of western reefer movements empty, and the fact that 35.1% of all reefer miles were empty, then eastern empty reefer miles must have remained close to the pre-service order, 1942 empty mileage percentage of 43.8%.The percentage quoted is the "total" for the US railroads. Thus some areas of the country could have had more loaded vs empty mileage, but the overall US average was as stated.
There were NOT lots of available mty XM's on the east coast during WWII. ICC Service Orders, Quota Orders and Car Service Division Special Car Orders were redirecting freight cars on a daily basis and the use of the refrigerator cars was an effort to maximize car loading and minimize empty mileage. Prior to WWII much of the traffic in the US was moving west to east towards the population centers. During WWII traffic patterns changed.
A significant part of the 3:1 loading was being done in the Midwest, but not all. Much of the loading was magazines, phone books, printed material and thru LCL cars. I cannot quote a percentage.
