Italo
Regionale/ Regionale veloce
The cheapest and slowest commuter trains with no reserved seating (just grab any free seat). The Regionale stops at every single station, while the Regionale Veloce only stops at major ones, getting you there faster.

High-Speed Trains:
Le frecce (Trenitalia)
Italo
Bright red trains, with a design handled by people who used to work at Ferrari. They only operate along the main high-speed corridors, meaning between major cities. They are often cheaper than Frecciarossa, especially if you catch promo codes that the company regularly posts on its social media.
