While browsing through a series of documents published by the Interstate Commerce Commission, I discovered something which might be of interest to us. Located page 811 of Interstate Commerce Commission Reports: Reports and Decisions of the Interstate Commerce Commission of the United States, Volume 347 is a table listing the Frisco's friendly connections at thirteen interchange points, along with the number of carloads interchanged. I have transcribed the data onto a spreadsheet and uploaded it in PDF form below.
