Metropolitan Transportation Authority (MTA) Assistant Conductor Practice Test

What indicates an approval for a Roadway Worker-In-Charge before work begins?

1. Standard operational procedure

2. Blocking Device Removed Code

3. Interlocking Limits verification

4. Track safety assessment

The correct answer is: Blocking Device Removed Code

The approval for a Roadway Worker-In-Charge before work begins is indicated by the Blocking Device Removed Code. This code signifies that any blocking devices which ensure the safety of the workers by preventing train movements through the work area have been properly removed, signaling the area is clear for the work to commence. In railroad operations, safety is paramount, and the use of blocking devices is a critical measure to protect workers on or near the tracks. The removal of these devices, alongside the assurance that appropriate safety protocols are in place, confirms that work can safely begin. This makes the Blocking Device Removed Code an essential part of the communication process regarding worker safety and operational procedures. The other options relate to aspects of safety and coordination, but they do not directly indicate the necessary clearance for the Roadway Worker-In-Charge to initiate work. Standard operational procedures provide guidelines, interlocking limits verification ensures that signals and switches are appropriately set, and a track safety assessment evaluates conditions but do not serve as a direct approval marker.
