Public Transport in Portugal over Easter

Hi,

Does anyone have any experience of public transport (particularly rail) in Portugal over the Easter period? Is there a reduced (or nil) service on any of the days. Looking to travel from Porto to Valenca\Tui by rail but, unfortunately, the Portugese Rail site doesn't offer timetables yet for 2011.

Thanks
Mig

For anyone else interested in Rail Transport around the Porto-Tui-Vigo area for the Camino Portugues here's a link to the timetable which includes daily, weekend and public holiday services.
