Re: Box car counts by RR - NMRA Charles collection

Rob Kirkham <rdkirkham@...>

Thanks Larry! Apart from the PRR, my impression - just scanning through the numbers - is that by incorporating the Canadian numbers (which are obviously underrepresented by fleet size, reflecting the border issues) the deviation between expected and actual in the Charles collection is reduced a little. I suppose one could test for that in Excel, although my first year stats course is more than a 1/4 century ago, so I won't be the one to do it...

A question: what is the Handbook of American Railroads - that's a new one to me. Is it analogous to the ORER? Published how frequently?

impact the figures.

There are 4 CP boxcars and 2 CN boxcars in the Charles collection. The
_Handbook of American Railroads_ doesn't include Canadian Railroads. I
added the CN and CP boxcar totals from the April 1951 ORER and revised
the table. Its in the files section with the file name _Compare box
car counts N Amer RRs - Charles collection.pdf_.
