I'm looking for information on trains traveling through any part of the Central division from 1940 to 1960. What quantity of traffic is moved each year? What roads interchange the most with the SLSF, and where? What are the numbers of the trains that carry this freight? What's the usual quantity of extras? Etc... Overall looking for information on how the freight moved on the Frisco! Specifically cars handled and # of trains, both on the timetable and off it. Thanks for the help!
