Passenger trains, lite locomotives and locomotives operating at the rear of a train must be equipped with an ____________ or have the rear headlight on ____________ at all times.

Passenger trains, lite locomotives and locomotives operating at the rear of a train must be equipped with an ____________ or have the rear headlight on ____________ at all times.

• A. Illuminated marking device / low beam
• B. Flashing beacon / high beam
• C. Reflective tape / medium beam
• D. Auxiliary light / high beam

Answer: (A)

The requirement is about ensuring rear-end visibility for trains with passenger equipment and for locomotives at the rear. To mark the end of the train clearly, the rule calls for an illuminated marking device at the rear, or, if that isn’t used, the rear headlight must be kept on low beam at all times. The illuminated marking device provides a steady, easily seen marker that stays visible to following trains and trackside observers, regardless of the locomotive’s headlight, while the rear headlight on low beam gives sufficient illumination without dazzling crews in the rear or on following trains. A flashing beacon, a higher-beam headlight, reflective tape, or other lighting options don’t meet the specified requirement for rear-end visibility in the same way.
