As part of a very much larger project, I am attempting to compile a reasonably comprehensive list (actually, a database) of passenger car consists, including the design and history of each car, beginning with the Southern Pacific Railroad; I recognize and am grateful for the work of others in the field, but what I am working on ultimately goes far beyond mere railroad data. Nevertheless, the specifics are important to my research.
I am presently stuck with what is probably the most bone-headed of problems for a researcher to have. Realizing that some cars are (were) acquisitions -- and occasionally conversions -- from other roads, and that some cars will by other roads be acquired and sometimes converted, my rolling-stock picture defines each configuration of each car between two dates, and associates routing and other information. So, here is my question:
Sleepers tend to be described with numbers that occasionally resemble Whyte steam locomotive designations (for example: "4-4-2"); however, those numbers respecting sleepers obviously doesn't refer to either the number of axles or wheels associated with a particular railcar. Making matters more confusing, some are described with numeric sequences such as "8-5" or "4-4-5-1." How do I translate these numbers for a useful understanding regarding the configuration of accommodations?
If there is no standard convention for such designations, please point me to a list indicating the practice used by each builder or (gee, I hope it doesn't get this complex) railroad. The main thing at this point is simply to understand exactly what is meant by each of those numbers.
For each car, I am looking for all the information containing important sociological clues: how many of what type of berths were configured in what orientation, what facilities were available and which were private, etc. I also need at least the coupled length of each railcar, and its tare and gross weights. Detailed dimensional data would be nice, but I can work around that on the assumption that each consist required interoperable equipment. I suspect the finished database will be quite large.
Thanks!
