Which speed is specified when a train must proceed at restricted speed and not exceed 40 MPH until the next signal is visible after entering a block that did not require restricted speed?

Which speed is specified when a train must proceed at restricted speed and not exceed 40 MPH until the next signal is visible after entering a block that did not require restricted speed?

• A. 40 mph
• B. 60 mph
• C. 25 mph
• D. 15 mph

Answer: (A)

Restricted speed means you must be able to stop within the distance you can see and proceed at a rate that allows you to comply with signals ahead. On most main tracks, the maximum under restricted speed is 40 mph, unless a lower speed is posted. In this situation, after entering a block that didn’t require restricted speed, you still must operate at restricted speed and not exceed 40 mph until the next signal becomes visible. The other speeds aren’t the standard limit for this rule: 60 mph would be too fast for restricted speed, and 25 mph or 15 mph would apply only in locations with more restrictive local rules or yard/siding areas, not the general main-track case described.
