mentioned, maybe a grace period of one digest would be in order. This list has unreasonable volume to get individual messages. when I want to and don't have the messages, or even the digests,

exactly True, but actually I was looking at the floor/underframe for one of Al's B-50-1/2/3/4 box cars, with the idea of trying a Harriman-era F-50-1/2/3 working from the photos in Chapter 9 of Volume

This is interesting. Do you know of any published photos? And hopefully not in some issue of the Keystone; the only one I have is Summer 1988. And heck, I have no idea what an X35 box car

Folks, I grow weary of this. No one has answered Tony's challenge to provide evidence that supports a "regional bias in boxcars" position. It seems that any evidence that does not support this

Um, Rich, The mean is the average. Are you thinking about the median? (the point at which half the samples are above that value and half are below)., Regards Bruce Bruce Smith Auburn, AL

refined noted Bruce, For UTLX, my '43 ORER tank tally has: 18830 - 8k TM 13666 - 10k TM 1008 - 8k TMI 3600 - 10k TMI plus 1556 under 8k, and 18 either over 10k or multi-compartment. I thought

I don't think we can draw too many conclusions on car distrubution based on the list of cars in the Charles Collection other than to marvel at the variety of cars which stopped in Harrisburg.

early battleships used Pilchers which are available from Bethlehem Car Works. The Lewis trucks are unlike anything on the market but are simple enough to scratch build. - Al Westerfield The Lewis

I believe that the random variables in this situation are the boxcar counts for each railroad. ================ The box car ownership counts themselves are highly biased. A significant

Average amd median are the same thing. total events/number of observations eg. you observe 100 trains and those trains have 273 ATSF cars in them. The average number of ATSF cars in a train is

Tim O'Conner says: "Mike Brock wrote Actually, it applies exactly to the Overland Route. Your samples are just too few to be statistically meaningful." My point again...as I've said from the first.
