Well, as usual, I am late to the fray...
I offer here a full service abstract for combined UP 161000-161099, 161100-161199. I'll make no comment on what you'll find as you work through leaving it to you to decide if there is concordance and care in reporting dwindling cars available for service in the ORER.


I have compiled service abstracts for all UP box cars built 1901-1942 and all their subsequent rebuildings and renumberings: 319 series overall. Only a few have been abstracted in such detail as the following but the others could be. Those that have been done in this way are consistent in the concordance of counts in the ORER and events in their service as life recorded in UP records with a nod to the delays encumbered by accident reporting and the US Mail. For all of the series, the final retirement of the last 10 or so *has* been compiled to provide individual car road numbers that made it to the end. The concordance of this "dwindling" in the ORER and company records is consistent.


I should add that the P&R series histories compiled by John Hall at :
http://www.readingmodeler.com/index.php/articles/rolling-stock-reference/99-rolling-stock-reference-files/freight/214-reading-company-boxcars http://www.readingmodeler.com/index.php/articles/rolling-stock-reference/99-rolling-stock-reference-files/freight/214-reading-company-boxcars

provide the raw material to similarly construct ORER / RR Record service abstracts. I have done so for some of the P&R series with similar results to the UP exercise. There are other sets of company records available, as well.


A copy of the UP service abstract has been uploaded to the file section. It will preserve the formatting making reading much easier. Open as an ASCI text.


Enjoy

I can only speak to the B&M, and only to an early era (teens to 1945). Every series that I have tabulated from the ORERs in my collection has declined in number in a systematic and even predictable way. This is especially true of the WUF cars that disappeared completely between the 1930 and 1935 registers that I own. I have no reason to believe that this does not represent a sincere effort to report the car counts as accurately as was reasonably possible (as per Tony's comment).


As for "company papers" that would tell a different story, if they ever existed for the B&M they are now at the bottom of some landfill in eastern MA (AFAIK). Mercifully, the B&M never renumbered their cars in the pre-WWII era or, if they did, this is easy to tease out of the registers.



Consequently, I find the ORERs to be a decent (at least) source of information to help understand fleet composition, and it's about all there is in this particular instance. I am particularly grateful for the sizeable number of these that have been scanned and made available at little or no cost.
