Cochrane Shops Car Man Lee maneuvers a wheel set onto "Rip 1" January 11th as he, Darin, and Rick run through the process of switching out plain bearing trucks to the more modern roller bearing trucks on one of ONR's 40 foot box cars. Wheels are moved around the rip by utilizing what's called a clam (the orange thing hanging from the forklift). The clam has two sets of clasps that clip onto the wheel set which enable the forklift to move the wheel set wherever they need it safely. The clam is also used to load and unload wheel cars.
