There used to be a narrow gauge railway which was ‘temporarily” closed in 2009 awaiting upgrading, but when the financial crisis hit the line was formally closed in 2012.
There is a bus service and buses go just about every hour in the morning and then less often but regularly through the afternoon. Journeys take 50 minutes and cost €7.60 see http://www.rodonorte.pt/ for schedules and current prices.
