Unless otherwise specified, speed restrictions apply to which train?

Unless otherwise specified, speed restrictions apply to which train?

• A. Lead Locomotive
• B. Passenger Train
• C. The entire train
• D. Freight Train

Answer: (C)

Speed restrictions are set for the track segment and apply to the train as a whole. When a limit is posted, the engineer must ensure the entire train operates at or below that speed, not just the lead locomotive. All units—the locomotive(s) and cars—must stay within the limit, since the train moves as a single unit and braking and acceleration affect the entire consist. If multiple limits are encountered along the route, the train must not exceed the most restrictive one. Only if a note specifies that a restriction applies only to the lead locomotive or to a particular type of train would that change.
