During periods of extreme weather with sustained wind speeds above 50 MPH, trains must be instructed to operate at a reduced speed of what MPH?

• A. 50 MPH
• B. 60 MPH
• C. 70 MPH
• D. 40 MPH

Answer: (B)

High winds create lateral pressures and gusts that can push a train off balance, reduce braking effectiveness, and bring debris onto the tracks. When sustained winds exceed fifty miles per hour, trains are required to operate at a reduced speed of sixty miles per hour to maintain a safe margin against these wind effects. This speed is chosen to balance safety with keeping service moving: it’s slow enough to improve stability and reaction time in crosswinds, but not so slow that it causes unnecessary delays. The other speeds wouldn’t match the mandated safety level: fifty would be insufficient in stronger winds, seventy would be too fast for the wind conditions, and forty would be more restrictive than the standard but isn’t the specified reduction.
