No, not all Italian trains are high speed; the network is divided into three main tiers. The "Le Frecce" (Arrows) are the high-speed stars: Frecciarossa (Red Arrow) is the fastest, reaching 300 km/h on dedicated tracks, followed by Frecciargento and Frecciabianca. There is also a private high-speed competitor called Italo. However, the vast majority of the network consists of Intercity trains (which connect larger cities at moderate speeds) and Regionale trains. Regional trains are the "workhorses" that stop at every small village and town; they are much slower and significantly cheaper. While you can zip from Rome to Florence in 90 minutes on a high-speed train, traveling between smaller towns in Tuscany or Sicily will almost certainly involve the slower, more traditional regional rail service where tickets do not require a seat reservation.
