Which piece of equipment can validate fares?

The piece of equipment that can validate fares is the platform validator. This device is specifically designed to check and confirm that passengers have paid the appropriate fare before they are permitted to board a train or use a specific area of the transit system. It often works in conjunction with fare cards or mobile fare apps, allowing for a smooth and efficient boarding process by ensuring that only those who have paid can access the services.

Train doors are primarily for passenger entry and exit and do not have the functionality to validate fares. The passenger information screen provides updates on schedules and services but does not engage in fare validation. Emergency exits are safety features to allow for exit during emergencies, and they do not play any role in fare validation processes. Thus, the platform validator is uniquely equipped to handle fare checks, aligning with the operational requirements of the transit system.
