At the beginning of the tour of duty, there must be a minimum of six red fusees and one red flag on each of the following:

• A. Lead locomotive; Shoving platforms; Occupied caboose.
• B. Every car in the train.
• C. The maintenance shed and yard office.
• D. The engineer's cab only.

Answer: (A)

The important thing this item tests is track protection at the start of a duty shift. The six red fusees and one red flag are portable warning devices used to alert other crews and approaching trains that a train or portion of a train is being prepared to move or is at the end of a work area. Placing them on the lead locomotive, on the shoving platforms, and on the occupied caboose ensures protection at the three critical points where movement or switching could occur: the front of the train, the area where cars may be shoved or moved, and the rear of the train. These locations are where visibility and warning are most needed to prevent collisions or accidental movements. Choosing these locations rather than placing devices on every car, in the maintenance shed and yard office, or only in the engineer’s cab makes sense because the purpose is to provide clear, practical warning for active train movements in the field, not to equip non-operational areas or every individual car with protection devices.
