Can anyone supply any information about the "Fast Freight Line" or lines associated with the KCFS&M, or with boxcars that may have been used by it? I know that in the late 19th century it wasn't unusual for railroads to have affiliated fast-freight lines that solicited high-value merchandise and LCL shipments. Merchants Dispatch was connected with the NYC; Union Line with the Pennsy; and so on. I've come across some documentation suggesting that the KCFS&M had its own "fast freight" line in the 1890s, which may have continued operating under the Frisco into the 1900s. I'd like know more if possible. In looking over some company documents of the KCC&S, I've come across references to regular monthly car mileage payments to the CF Collins Fast Freight Line in 1895 and the JW Soady Fast Freight Line in 1896. From the way these appear in the documents, they appear to be affiliates of the KCFS&M and its subsidiary companies. In the 1897 and 1900 ORER entries for the KCFS&M, there is a group of boxcars which are described as follows: Box, Fast Freight Line. Car numbers 30000-30199. Inside dimensions Length 33' 5.75"; Width 7' 11.75"; Height 7' 1.25". Capacity 60000 lbs. Number of cars: 200. A 1903 Frisco rolling stock roster indicates that 186 of these cars were still in service, lettered KCFS&M. It also indicates that they were built in 1894 and lacked air brakes. They are simply described as 34-foot boxcars, with no special "fast freight" designation. (Possibly just an omission, given the data below.) In the 1905 SLSF ORER entry, these cars appear again, apparently still lettered KCFS&M, designated "fast freight" and bearing the same numbers, although diminished in number to 181. In the 1911 ORER, the next one I have access to, it looks like there has been a lot of reshuffling and renumbering of the freight fleet. I don't see any obvious series of boxcars that exactly corresponds to the KCFS&M 30000-30199 series dimensions. I'd be very interested in any information about the appearance, use, and operation of these or any other "fast freight" cars used by the KCFS&M or the CF Collins or JW Soady Fast Freight lines.
