So, here's a philosophical question... For my foreign boxcar fleet, I need roughly 5 B&O boxcars based on the national fleet. So what cars? Well the WWII fleet consisted of the M15, M26 and rebuilt M15 and M53 wagontops. The knee jerk response of many modelers might be to use the iconic wagontops. After all, you can identify them as B&O without even reading the reporting marks! But I can't resist the temptation to educate and the wagontops turn out to be a cliche. Their combined made up just over 10% (or 1 in 10) of the B&Os boxcar fleet.. .=========== Let's not get too hung up on averages. After all, the average day rarely happenned. If 10 % of the cars were wagon tops, then there were probably days when out of ten cars five would be wagons. So you're modeling that one day in 20, but it wouldn't be reasoanble for anyone to suggest that you are unprototypical.

However, due to the size of my fleet that car will not appear everyops session, but several B&O cars will.

There are a lot of ways to get the exact layout mix that suits you, limited only by the amount of number-crunching you want to do. You could just look at the exact car classes for each road and again go with the most common. That was too much work for me for the 15 or so RRs I had in mind, because I didn't want to have to track down whether a NYC Lot B-567 car was really the same as a B-702 car and the like. I did want to get a proper mix of long and short cars though.

My assumption was that for my industries and loads the car length was not relevant. What I did after looking at all XM distribution was to determine the ratio of 40-ft to 50-ft XM cars, which was exactly 4:1. So if my RRs by pure XM numbers were PRR (8 XM), NYC (6 XM), and ATSF (6 XM) I figured I needed sixteen 40-ft and four 50-ft cars. Looking at the distribution by car length showed that PRR did not have that many XM 50-ft cars and NYC and ATSF were about equal, so the breakdown was 8x 40 PRR, 4x 40 NYC, 2x 50 NYC, 4x 40 ATSF, 2x 50 ATSF. With that out of the way I looked at the most common cu ft - length pair for the road. As these could represent several car designs I made a matrix for that cu ft of width and height to segregate them. Usually one car class was strongly dominant (at least 10% more than the next) so that's what I chose to model. When there wasn't a clear leader I went down the line until there was a 10% space and decided to live with any of the top types. Just my rambling, but one thing useful in all that is it is probably worth have some tolerance in your numbers - if the "leader" isn't at least 10% (or whatever) more than number 2, I think it is perfectly reasonable to substitute something from number 2 in the interest of modeling expediency.

the real world of railroads was usually didn't work.

This gets back to my initial concern - we may need to make sure our trains don't look "too" average. For rolling stock switched during an op session, let things fall where they may, and perhaps stay near the national average for deliveries from staging, but for a run-through consist, or a large block that transits a yard but is not spotted to a customer(s), but instead runs back into staging, hitting the average all the time may not look prototpical.

I can't tell you some amusing tales about trying to apply linearprogramming to car distribution because that clearly required after 1961 computer capability. Malcom, Thanks for the insight from the OR perspective. Did anyone ever try to use OR to analyze historical data to see if they could spot some unknown operational problem/trend rather than solve an immediate problem? I would expect not since the people on the ground probably knew what the problems were - very different from telephones where the lack of human involvement (relative to the number of "events") led to a lack of information. Appreciate the programming humor. As an engineer that graduated about the time the PC came out, I'm continually amazed at how much analysis was accomplished during the days before computers. Lots was done in the 60's and 70's with main-frames and mini-computers, but before that - Wow! and often with very large data sets. Thanks for the help, Dave Evans
