Thanks, desi, for posting this.
It's most strange. If I access the EAV site directly, I'm still sent to the 2016 timetable.
Even stranger, if I follow your link and then use the "Assistenza" button at the top of the 2017 timetable page, the links to the Campania Express return me to the 2016 timetable! I cannot reach that page independent of your link... (The complaint about this service being underutilized will certainly not be addressed by hiding the timetable)
Good on you for finding this and thanks again for capping this thread by posting the link.
