Re: Ratios of Home Road vs. Foreign Roads

Dana and Larry Kline <klinelarrydanajon@...>

I agree with Richard Hendrickson that photographic or other documentation is
the best approach to determining the ratio of home road and foreign road
cars. The photos and videos available to me show that boxcars are, by far,
the most common car type in WM merchandise trains, and that foreign road
cars are much more common than home road cars.

It is interesting to compare the data from photos and videos with Copeland
Report data. On the Western Maryland all merchandise traffic to and from the
west was interchanged at Connellsville, PA. The WM 1952 Copeland Report
gives the following numbers of cars interchanged at Connellsville.

P&LE 29,228
P&WV 28,783
B&O 3,310
PRR 2,577
P&LE 34,583
P&WV 44,287
B&O 1,039
PRR 293
Total Eastbound+Westbound 144,100

The WM had 2,284 boxcars as of January 1953. Assuming a typical value of
one car turn per month, the total number of WM boxcar shipments in 1952 was
about 27,000. Only a fraction of these shipments would have been
interchanged at Connellsville. Thus, home road cars can account for only a
small fraction of the cars interchanged at Connellsville and one would
expect that most boxcars in WM merchandise trains would be foreign road
cars, as suggested by photos and videos.
