For volume of cars, the largest customer on the line was at one time GAF at a section of track in East Chester near the CSX interchange. GAF has stopped shipping as much by rail. Archer-Daniels-Midland in Kershaw is currently the biggest customer on the line with estimates ranging up to 4,000 cars a year. Circle S at MM17 on the Original 29 handles some 3,500 cars a year. Furthermore, there is a shuffle train between the two feed mills. This was billed as an added bonus to L&C operation of the SB. Formerly, 18-wheelers, up to 60 a week, handled this traffic.
