Can I tap a bank card on an Adelaide train for a one-off city trip?

Use the official journey planner for your station and date. If travelling together, check whether each person needs a separate card or ticket.

Confirm the fare and accepted card type before boarding, and keep a backup ticketing option. A rollout described in an old forum post may have changed.

Check the current Adelaide Metro payment page for trains specifically; a tap option on buses or trams does not prove the same equipment is active on rail.
