I would imagine that it might be possible to return via Locarno and to
take the SSIF/FART to Domodossola and catch the CNL train there. I
don't know what time the CNL stops in Domodossola, so I don't know if
there is a close connection or not.
I could not find reference to the Sunday route on www.reisezuege.ch
I will have to look into it further.
