Engines and cars must not be operated through water which exceeds how many inches from the top of the rail?

• A. 3 inches
• B. 2 inches
• C. 4 inches
• D. 1 inch

Answer: (A)

Safety when operating through water on the tracks depends on how deep the water is relative to the rail. If water is deeper than three inches above the top of the rail, traction and control can be significantly reduced, making it easy for wheels to slip or slide and for the train to stall. Water this deep can also conceal defects, wash ballast away, and create hazardous conditions that increase the risk of a derailment or damage to equipment. Because of these risks, engines and cars must not be operated through water exceeding three inches from the top of the rail. If you encounter water that deep, stop and find a safe alternative route or wait for the water to recede.
