Medium Speed is defined as which of the following?

Medium Speed is defined as which of the following?

• A. Not exceeding 25 MPH.
• B. Not exceeding 50 MPH.
• C. A speed not exceeding 30 MPH.
• D. A speed used for yard switching.

Answer: (D)

Medium speed is an operating category tied to yard switching. It refers to the pace used when moving and rearranging cars within a yard, where precise control around switches and equipment is essential. The idea is that the speed isn’t defined by a single numeric limit, but by the task being performed in the yard environment. That’s why the correct choice describes it as a speed used for yard switching. The other options imply fixed mph limits that apply to different contexts, such as general mainline running, which isn’t the definition of medium speed in NORAC rules.
