What is Medium Speed defined as for passenger trains?

Medium Speed for passenger trains is defined as a maximum speed that does not exceed 30 MPH. This definition is important because it establishes the speed at which trains can operate safely in various contexts, particularly when approaching stations, handling station stops, or traversing areas that may require caution due to curves, grade crossings, or adjacent pedestrian activity.

Understanding the limits of medium speed is crucial for conductors and operators in ensuring passenger safety and maintaining efficient operations. While the term "medium" suggests a balance between slow and high speeds, the specific threshold of 30 MPH is established in regulations to enhance safety protocols in environments where train dynamics can significantly impact operational integrity and passenger experience.

The other options do not accurately reflect the definition of medium speed within the context of passenger trains, as they set speed limits either lower or higher than the established standard, which could lead to confusion and potential safety risks if applied incorrectly during operations.
