How does the NORAC define 'Normal Speed'?

The definition of 'Normal Speed' under the NORAC pertains to the operational framework for train movements and safety. It refers to a speed that does not exceed the Maximum Authorized Speed, which is a critical component in ensuring safe operations within the railroad network.

When a train operates at a Normal Speed that adheres to this definition, it helps maintain proper control and limits the risks associated with excessive speeds. understanding this concept is crucial for railroad employees as they adhere to safe practices while managing train operations.

In this context, other options do not capture the regulatory compliance and safety concerns that the definition of Normal Speed encapsulates. Operational practices such as typically operating speeds or speeds required specifically for freight do not provide the same level of safety assurance as maintaining operations within the bounds of Maximum Authorized Speed. Thus, option C is the most accurate representation of how NORAC defines 'Normal Speed.'
