After receiving a "NO DEFECTS" message, what is the maximum speed at which the train may proceed?

When a train receives a "NO DEFECTS" message after a mechanical inspection, it indicates that no issues or defects were found with the train that would impede safe operation. This assurance allows the train to proceed at a speed that is deemed safe and appropriate given the condition of the train.

Typically, the "NO DEFECTS" message allows trains to operate at a speed limit that aligns with regulations and safety protocols established by the railroad or governing safety bodies. In this case, the maximum speed of 30 MPH is correct. This speed strikes a balance between maintaining safety and operational efficiency, allowing the train to continue its journey without undue delay while ensuring safety measures are still in place to respond to any unforeseen circumstances.

This speed reflects standard practices within the rail industry when conditions are normal, and inspections have confirmed the train’s readiness to operate. It’s worth noting that exceeding this speed could pose risks if any undetected issues arise, thus emphasizing adherence to set guidelines for operation following inspections.
