Your train is passing standing equipment on an adjacent track. It is a requirement to have the bell on when the locomotive is leading the movement.

• A. False
• B. True
• C. Only at night
• D. Only on double-track lines

Answer: (B)

When a locomotive is leading a movement near standing equipment on an adjacent track, the bell must be on to provide an audible warning to anyone on or near the right‑of‑way. The bell is there to alert workers or others who may be around the adjacent track or the standing equipment, especially in areas where visibility or attention might be limited. While the horn is used for distant warnings and for crossings, the bell offers immediate, close‑range notice as the train moves past nearby equipment. This requirement applies whenever the locomotive is leading, regardless of the time of day or the track layout. So, having the bell sounding in this scenario is the mandated safety practice.
