Yes, the little train still runs. Here's the schedule:

Hi I was interested to read these posts about a train to the beach. I've recently been to Odeceixe (in June) and didn't see the train or any adverts for it. We had a nice walk to the beach - but it's not ideal because it's along the road and would be tiring in very hot weather. Has anyone actually used the train this year? I'd like to go back to Odeceixe next year and a train to the beach sounds like a good idea.

I was there last August and did not see any train or any publicity about its existence...
