Validate CP Rail Tickets Before Boarding

When traveling across Portugal on suburban and regional rail lines run by CP (Comboios de Portugal), buying a ticket is only the first step. You must validate your magnetic card or physical ticket at the yellow or green scanning totems situated on the platform before stepping onto the train carriage.

Unlike many modern transit systems worldwide, Portuguese train platforms frequently lack turnstiles or physical barriers to block entry. Boarding without a stamped electronic validation timestamp carries hefty on-the-spot fines starting at dozens of times the fare price, with ticket inspectors showing zero tolerance for unaware tourists.
