Rhätische Bahn
Rhätische Bahn runs regional and touristic services between Tirano (IT) and Sankt Moritz (CH).

Alto Adige Mobilità / Südtirol Mobil
Trenitalia and SAD run regional services between Austria and Italy on routes 100 (Innsbruck (A) - Bolzano (I) - Trento (I) - Verona(I)) and 400 (Lienz (A) - S. Candido (I) - Brunico (I) - Fortezza (I)). Timetables on Alto Adige Mobilità / Südtirol Mobil site
Tende railway
Trenitalia runs regional trains between Piedmont, Alpes-Maritimes and Liguria (Fossano (I) - Cuneo (I) - Tende (F) - Ventimiglia (I)). Due to Piedmont railway ineptitude from 2010 onwards, few trains runs along this route.
Other italian "international" services
- BLS runs trains between Brig (CH) and Domodossola (IT). Some come from Bern (CH), the Swiss capital. This is a somewhat fuzzy international service, because Domodossola is a border station (with customs), so the line is formally in Swiss, but there are 18 km and 3 stations in Italy before the actual border (and Piedmont region pays for Domodossola - Iselle service).
- Trenord runs S11 Milan suburban line between Chiasso (CH) and Milan (IT). However in Chiasso station there are "formally Italian tracks" S11 terminates on, so formally S11 trains never enter Swiss.
- Turin SFM line 3 runs till Modane (F), but again Modane has "formally Italian tracks".
