What color indicates that a switch is in the normal position for a train?

The color that indicates a switch is in the normal position for a train is green. In railroad signaling, colors are used to convey critical information about track conditions and switch positions. Green is universally recognized as a signal for “go,” meaning the track ahead is clear and safe for the train to proceed.

When a switch is in its normal position, which means it is aligned for the main track, the green indication signifies that trains can continue safely without obstruction. This is crucial for maintaining the flow of train operations and preventing accidents or misrouting.

Other colors serve distinct purposes: yellow may indicate caution or that a switch is positioned for diverging tracks, red typically signifies stop or danger, and blue can be used in specific contexts, such as maintenance of way procedures. Understanding these color codes is essential for train operators to ensure safe and efficient train movement.
