What is the distance to indicate an approaching Slow Speed Order?

The distance to indicate an approaching Slow Speed Order is typically set at 3,500 feet. This distance is established to provide engineers ample time to react and reduce speed appropriately as they approach zones where speed restrictions are enforced. The advance warning is critical for safety, allowing for a gradual change in speed and ensuring that trains can comply with the slower limits without abrupt stops or risks of derailment.

In real operational scenarios, having a clearly defined distance helps maintain consistent train operations and enhances overall safety protocols within the transit system. By allowing sufficient time to prepare for the slower speed, the chance of incidents due to sudden speed changes is minimized. Understanding this distance is crucial for train engineers in order to follow regulations and maintain safe operations while navigating areas with speed restrictions.
