We've been down this road too -- most people take photos of stuff they happen to like, or that catches their interest. Almost no one took photos (and expended film) in order to document "typical"

This is the other factor in this essentially impossible and largely meaningless exercise in trying to figure out how many cars of each type would typically be seen on a train in the time period

Mike Brock wrote Mike, he ran 100,000 iterations of a 40 car box car train, composed of cars chosen randomly from every possible prototype. The National % is obvious, and then he finds the AVERAGE %

Tim O'Connor writes: "Good work, Larry! That's what I'm talkin' 'bout! A 40 car train with 9 SP (not counting T&NO) box cars.." I assume you mean a train with 40 box cars. Actually the 1949 trains

Brian, If you're thinking of Pennsy's 2D-F12 truck, then no. It's different. It has the distinct V-9306 sideframe with room for only one leaf and two coil springs, whereas the trucks on my list of

Tim, Here's some railroads I know of that used the double truss coil- elliptic sprung 40 and 50 ton trucks, with or without spring planks: C&O, CGW, WM, BAR and Erie used them on some or all of

You mean 46759? There is no 46795 in the 1940, 1950, or 1953 ORER's.
