What is advised regarding contact between the pantograph pole and the wire?

The recommendation to avoid contact between the pantograph pole and the wire at all times is based on safety and operational protocols essential for train functionality. The pantograph, which is the device mounted on the roof of electric trains, is designed to maintain contact with overhead wires in order to draw power. However, any unintended or excessive contact can lead to electrical arcing, which can damage both the pantograph and the overhead wire, potentially resulting in dangerous situations such as electrical failures or fires.

Maintaining a safe distance ensures that the pantograph operates within its parameters to avoid mechanical wear and tear or failures that could compromise train service. Proper training emphasizes the importance of this advice, ensuring that conductors understand the need to monitor the interaction between the pantograph and the wire actively and effectively to uphold safety standards and minimize equipment malfunctions.
