Step free access to all platforms of the station. Also, ticket barriers are usually open when you enter the station from the platform 1 step free entrance.
If your train is from Platform 1 and you need a quick ticket, go through the underpass from the ticket office and use the machine next to the stairs/lift. No queueing, unlike at the main building
