Which components are avoided when climbing on or off a train?

When climbing on or off a train, safety is paramount, and specific components should be avoided to prevent accidents and injuries. The correct choice highlights components like the drawhead, running rail, and third rail protection board.

The drawhead is the part of the coupler system that connects railcars, and getting too close to it could lead to serious injuries, especially if the train is in motion or if there is a risk of uncoupling. The running rail refers to the track itself, where any slip or misstep can lead to falls or loss of balance. The third rail, which provides electrical power to the train, poses an electrocution hazard, and the protection board is essential in ensuring safety around this energized component.

Thus, these components are avoided because they present significant physical and electrical hazards while climbing on or off a train.
