What must trains operating in DCS territory check before crossing a hand-thrown switch?

Before a train crosses a hand-thrown switch, it is crucial to ensure that the switch is properly lined. This means that the switch is set to allow the train to safely proceed in the intended direction without derailing. A switch that is improperly lined could lead to a catastrophic event, as the track configuration would not match the train’s movement path.

The importance of this safety check is underscored by the potential hazards associated with hand-thrown switches, which require manual adjustment and can sometimes be misaligned due to human error or external factors. Ensuring that the switch is properly lined is a foundational safety protocol in train operations, especially in DCS (Dispatcher Controlled Switch) territory, where train movements are often governed by specific operational rules.

By prioritizing this check, train crews significantly enhance operational safety, reducing the risk of accidents and ensuring smooth transit through potentially complex track arrangements.
