You threw me for a few minutes. The only Vesuvio I knew is in Italy. Just searched here in Portugal on Google maps and found nothing.
However, just done another search on the Portuguese web!
Do you mean:
QUINTA DO VESUVIO??? The famous port wine vineyard on the Douro???
See:

I have placed a link to the downloadable railway timetable for the Douro Line (in pdf format) on my blog at:

Scroll down on the right and you will find at panel entitled:
»» Algarve & Portugal - Travel Transport Links
In this panel look for and click the link entitled:
>> Linha do Douro - Porto/ Régua / Pocinho
