What is permissible speed when authorized by RWIC Bailey in the working limits?

The permissible speed when authorized by RWIC Bailey in the working limits is typically set at 25 MPH. This standard is put in place to ensure safety while allowing for efficient movement within work zones. The speed limitation is designed to protect workers present in the area by reducing the risk of accidents and providing enough time for train crews to react to any unforeseen circumstances. The 25 MPH limit strikes a balance between operational efficiency and safety considerations, making it a crucial guideline for any rail operations within working limits.

While other options may suggest different speeds, they do not reflect the established standard set for these conditions. Thus, 25 MPH is recognized as the safe and permissible speed in this context.
