My husband and I plan to go to Ostia Antica by train from Roma San Paolo station. I know the train is part of the Metro system and uses Metro tix. RS describes getting to the train from the Piramide Metro stop and using your Metro tik to board. But we will be walking to the train station, not taking the Metro. Does anyone know how you validate your Metro tik to get on the train? Is there a turnstile to go thru or is there a validation machine on the train platform?
Also, anyone who has used this train: any comments on it? I assume for the return the Ostia Antica station has a validation machine on the platform. Correct?
Also, anyone know if you can still buy Metro tix at tobacco shops or will need to buy at a machine in a Metro station? We are low-tech people and will be buying paper tix, not using a smartphone.
Thanks
