What is the location of the high voltage jumper cables in M-3 cars?

The high voltage jumper cables in M-3 cars are located on the south side. This positioning is critical for safety and operational efficiency. By placing the jumper cables on the south side, it helps facilitate easier access for maintenance and troubleshooting while ensuring that the high voltage connections are secure and less prone to exposure to the elements or potential damage.

Considering the operational design of multiple unit cars like the M-3s, this arrangement allows for effective connectivity between cars when they are coupled together. It also takes into account safety protocols, minimizing the risk of inadvertent contact with the electrical systems during operations or maintenance tasks. Understanding the significance and reasoning behind the placement reinforces the importance of adhering to safety measures while working with high voltage systems in train operations.
