This view was taken while switching Kimberly Clark in North Memphis. All signals are taken on the fireman's side. This plant is completely switched three times a day, seven days a week. There are nine tracks to switch and spot. Sometimes as many as 125 cars are handled in an eight-hour period. N-37 shows spotting cars in track #4 which holds approximately 5 cars, all enclosed under a building with nothing but a trick wall and wheel stops at the end of the rail. There are seven of such tracks that are enclosed under a roof and all signals are taken on the fireman's side.
