Italy havend published the timetable for the 2nd half of the year small timetsvle change on 12th June
Lisbon- Mardrid currently no direct trains atleast 2 changes needed :/
Greece doesnt share the timetable 
from Patras to Athens you can look on the Website of "Trainose" greek rail for the connection
Igoumenitsa is in Greece and there's no rail connection. If you're coming from Bari, then there's a direct ferry Bari - Patras (via Igoumenitsa) run by Superfast (Interrail is valid but you'll still need to pay for accommodation and certain taxes/surcharges).
@rvdborgt on Superfast you get just a discount with the Globalpass
The greek Island pass 6days users can travel for "free"
@rvdborgt on Superfast you get just a discount with the Globalpass
Superfast say clearly that on their international lines, the deck passage is free (dormitory/airline style seat in 1st class).
@rvdborgt
Hmm strange. I asked them and they said no the Free trips are only for Greek Island pass holders like mentioned on the Interrail information pages https://www.interrail.eu/en/plan-your-trip/trains-europe/ferries/superfast-ferries
I will ask them once more with the link to their own page :D
Thanks rvdborgt :)
@rian and seewolf: I checked-as there were so many recent Qs about that ferryline and when trying to make a dummy-booking: there is NO way to enter anything like IR/Eurl, they state a 30% discount for junior and 20 or so for senior. There are also basic/shoulder and peak prices.
In other sites I´ve read that it is merged with another ferryline (there used to be several doing Gr-IT to various ports) but since corona the nr of trips has been much reduced and it also seems some of those companies have pooled together.
In the distant past-remember, old IR-passholders? before 2000: then it was like you could only get free IPA=stand by places on the port-office after the cut-off (3-4 hrs before departure) for other types of booking-so in hi-season many would left stranded and try again next day-or cough up for normal tickets to make sure.
But it would be nice and helpful if someone has the uptodate info on how it works for now. (and do not believe at all the statements in the Eu/IR site-in fact I would like to start a topic like ´spot the errors!)
@mcadv There is a topic like spot the errors 
And @rvdborgt and i post regularry errors that we found on the pages of Eurail/Interrail in this topic (I guess you can´t see it as it´s in a own category)
