A pair of Grand Trunk Western GP38-2's, 4933 and 4914, switch Rowell Chemical on a hot and hazy afternoon along the Chicago Sanitary and Ship Canal in Willow Springs. Dubbed L535, this train originates at Glenn Yard and services various industries. This business is one of CN's regular customers along the old GM&O in Chicagoland. Both GTW units wear the classic blue/red and are both former Missouri Pacific units built in 1972. The old GM&O mains (now CN Joliet Subdivision) can be seen to the right, along with the rest of 535's train.
