"I got a job working graveyard as what they called a pitman. They were scaling the diversion tunnels at that time on day shift. Graveyard shift would go down there with a 2,300-volt electric Marion shovel and muck out the material that they had shot during the day shift. My job was to back the trucks in so the operator on the shovel would not have to swing too much to load the trucks. They had lights that illuminated well enough so you could see what you were doing. The truck drivers had a throttle on the running board, so they could stand up and look and drive it backwards. Harry Hall "I worked with a gang of laborers, and we had to clean up the rock before they poured the concrete. The rock had to be clean. My job was to use a shovel and pick up as much rocks possible. Then they'd wash the rest of the rock up with high-pressure water. I only had that job about 10 days. I got firedthank goodness. "49 - Steve Chubb Gas-air shovels loaded the trucks, which hauled the muck out of the canyons to waiting train cars. Then the empty trucks raced backward down the winding canyon grades to the tunnels. The drivers stood to steer their trucks, looking back over their shoulders with one foot on the gas. That way the trucks backed up against the tunnels ready for another load rather than needing to be turned around. Steam locomotives hauled the muck from the lower level on a track along the right-of-way above the River Camp, seen in the background. Side-dumping cars increased efficiency. Then, once the tunnels were mucked out, the rock had to be cleaned so the concrete would set.
