{{short description|Area where a train is forced to slow down in the United States}} {{Unreferenced|date=December 2021}} In the United States, a '''slow zone''' is an area where a train is forced to slow down for either structural, construction, power, signal, or track problems. Slow zones limit a train to about {{convert|10|to|35|mph}}. Notification to train crews is referred to as a "slow order."
In the United Kingdom this is called a speed restriction.
