The direction of coal cars is controlled by tracks; therefore, other objects must have adequate clearance from the side of the coal cars.

• A. True
• B. False
• C. Not sure
• D. Sometimes

Answer: (A)

The main idea is that moving coal cars are confined to their tracks, but that doesn’t eliminate the need for space around them. Even when direction is controlled by the track, cars can still move slightly, shift on curves, or roll if brakes release or a switch is misaligned. The sides of coal cars, including couplers and any projecting hardware, can pose a pinch or crush hazard to nearby equipment and personnel. Maintaining adequate clearance on the sides keeps workers safe from being struck, crushed, or caught between the car and other objects, and it also prevents interference with operations along the track. So, ensuring side clearance is necessary, making the statement true.
