Are interlocking signals bypassed by track warrants?

• A. Movement must comply with interlocking signals and route constraints.
• B. Yes, warrants bypass interlocking signals.
• C. Only for maintenance blocks.
• D. Only for authorized personnel.

Answer: (D)

The main idea is how a track warrant relates to signal protection. Interlocking signals provide a safety barrier that governs train movements and route legitimacy. A track warrant grants authority to move within a defined block, but it does not give everyone the power to ignore interlocking protections. The nuance here is that any action that effectively bypasses interlocking would be restricted to those with explicit, authorized authority and proper procedures in place. That’s why the correct choice emphasizes that bypass privileges are limited to authorized personnel. In contrast, ordinary movements must still respect interlocking signals and route constraints, warrants aren’t a blanket bypass, maintenance blocks aren’t the only case, and bypass rights aren’t granted to just any crew member without the proper authorization.
