Understanding MRT Train Operations: Driverless Systems vs. On-Board Staff

MRT trains in many systems are designed to operate autonomously, but this raises a common question: if trains are driverless, why do I see what I assume to be drivers walking through the carriages mid-journey?

Why MRT Trains May Still Have Personnel on Board

In some advanced driverless train systems, there are still personnel on board for safety and operational reasons. These staff members, who are not traditional drivers, can serve as train attendants or safety officers. Their roles include passenger assistance, safety monitoring, emergency response, and system checks. These staff members can provide critical support to ensure the smooth and safe operation of the trains.

Passenger Assistance and Information

One of the primary roles of staff on MRT trains is to assist passengers. They can help with inquiries, provide information, and ensure that everyone is safe and comfortable during the journey. This direct interaction with passengers is essential for maintaining high customer satisfaction and addressing any issues that may arise during the journey.

Safety Monitoring and Emergency Response

These staff members also monitor the train's operation and passenger behavior. They can quickly respond to emergencies or issues that may arise. For example, in the event of a medical emergency or suspicious behavior, the presence of staff can facilitate a quicker and more effective response.

System Checks and Manual Driving

Staff on board can also conduct routine checks of the train's systems and equipment. In some cases, they may need to take control of the train manually if the automatic train operation (ATO) subsystem fails. This ensures the train can continue to operate safely and that passengers can be evacuated or re-routed if necessary.

The 1987 Original MRT Train System

It is important to note that not all MRT systems are driverless. In the case of the MRT system in question, which was built in 1987, the trains are still driven by human operators. However, parts of the system were automated in 1987, meaning that certain operations are controlled autonomously by the train's onboard systems. The newer lines, such as the North-East Line (NEL), are indeed fully driverless, but the original MRT system still requires human operators for safety and operational reasons.

Staff Roles When Trains are in Motion

When you see staff members walking through the train carriages during a journey, they are not driving the train. If the train is operating normally, they are likely performing their designated tasks, such as assisting passengers, conducting ticket checks, or providing customer service. However, in case of an emergency, such as a signaling fault with the automatic train operation (ATO) subsystem, these staff members can step in to drive the train manually or manage the situation effectively.

These roles are crucial for maintaining the safety and security of the train and its passengers. While the trains themselves are designed to operate autonomously, having staff on board can enhance service and safety, providing a hybrid system that combines the benefits of automation with human oversight.

Conclusion

MRT trains operate in a complex ecosystem where human intervention is still necessary alongside automation. Understanding the roles of staff on board can help clarify any confusion about the operation of these trains. Whether a train is fully driverless or has human operators, the safety and comfort of passengers are always the top priorities.
