Is It Safe to Touch the Return Rail on the London Underground?

When traveling on the London Underground, it is absolutely not safe to touch the return rail. This rail is a critical part of the electrical system that powers the trains and carries a high voltage of electricity, which can result in serious injury or even death.

Understanding the Electrical System

The London Underground's electrical system is designed to provide power to the trains. The return rail plays a crucial role in this system, completing the circuit that powers the tracks. This rail carries a high voltage, typically around 750 volts DC, and is interconnected with other parts of the system to ensure safe and efficient operation.

Safety Regulations and Numbers

The London Underground has strict safety regulations in place to protect passengers and staff. It is vitally important to stay behind safety barriers and to follow all posted signs and instructions while at stations and on platforms. If you see anything on or near the tracks, the best course of action is to alert a member of staff rather than attempting to retrieve it yourself.

Understanding the Risks

Even if you have been trained and briefed by the Site Person in Charge, touching the return rail remains extremely dangerous. The track system can have potential discharge points, and as trains frequently run on the rails, there is a significant risk of electrocution. Therefore, under no circumstances should you come into contact with the rail.

Common Misconceptions

There are also some common misconceptions about touching the return rail. For instance, there is no such thing as a "safe" part of the rail. The entire structure poses a risk due to the high voltage it carries. Additionally, performing any form of urination or other actions on or near the return rail is extremely dangerous and should be avoided at all costs.

Conclusion

The safety of the London Underground is of paramount importance. It is critical for all passengers and staff to adhere to the strict safety regulations and guidelines provided. Any deviation from these rules can result in severe harm or even death. The return rail, while part of the electrical system that makes the subway network function, is not just inaccessible but also hazardous. Therefore, it is never safe to touch the return rail.
