A track signaled in both directions (261); A signal indication will be the authority for train to operate in __ on the same track.

• A. Forward only
• B. Either direction
• C. Backward only
• D. Upward direction

Answer: (B)

When a track is signaled in both directions, signals are placed facing both ways, so each signal provides authority for movement in the direction it’s facing. The indication you see determines the allowed travel path, and because the track supports movement in either direction with its opposing signals, the authorization can apply to either direction. Thus, the signal indication will govern operation in either direction on the same track. The other options would apply only if the track were limited to a single direction, and “upward direction” isn’t a standard rail term.
