What must an employee provide upon the request of a passenger?

An employee must provide identification number, train number, and other necessary information upon the request of a passenger to ensure transparency and help the passenger understand their journey better. This practice enhances passenger safety and comfort by allowing them to verify the legitimacy of the employee and the service being provided. Such information is critical in maintaining accountability and trust in the operation of transportation services.

Supplying only personal identification or the train's schedule would not fulfill the passenger's need for clarity or assistance regarding their specific journey. Emergency contact information is also not typically required in response to a passenger's inquiry and does not pertain to the immediate operational details or service-related information that a passenger may seek. Therefore, providing comprehensive and relevant details as mentioned ensures that the passenger is well-informed and confident in their travel experience.
