What do running rails comprise?

Running rails are the essential components of a railway track that provide the surface on which trains move. They are typically made of steel and are designed to support the weight of the train as it travels along the track. The running rails play a crucial role in guiding the wheels of the train, ensuring stability and safe transit. Understanding this is vital for roadway workers, as they need to recognize the significance of the running rails in maintaining safe operations and preventing accidents.

The other options, while related to aspects of railroad safety and operations, do not accurately describe what running rails are or their specific function in the railway system. For example, areas designated for maintenance equipment or safe walking paths are important for worker safety but are distinct from the basic function of running rails that facilitate train movement.
