If all auxiliary lights fail en route, the train must not exceed how many MPH while the leading end of the train is operating over a public highway crossing at grade, and the auxiliary lights must be repaired at the nest forward repair point?

If all auxiliary lights fail en route, the train must not exceed how many MPH while the leading end of the train is operating over a public highway crossing at grade, and the auxiliary lights must be repaired at the nest forward repair point?

• A. 20 MPH
• B. 25 MPH
• C. 30 MPH
• D. 15 MPH

Answer: (A)

When auxiliary lights aren’t working, the protection they provide at grade crossings is lost. If the leading end of the train is spanning a public highway crossing, safety rules require you to restrict speed to 20 mph to give the crew enough time to observe the crossing and react, reducing the risk of a failure to stop or clear the crossing. The lights must be repaired at the nest forward repair point, which is the forward-most location on the train where a safe repair can be completed without moving the train backward. Once the defect is repaired, normal speed can be resumed.
