ViaggiaTreno displays an train-map of the entire country, useful by itself for visualizing how and where trains run. Color-coordinated highlights indicate train delays (in ritardo) by 15, 30, and 60 minutes, with arrows signifying the direction in which they occur. You can filter the trains according to type: Eurostar, Intercity, Regionale, etc, and click on an individual route for more detail. Clicking the TrenOnline tab provides status of any train en-route by typing its number in the field provided. (The train number will be on your ticket, your Ticketless voucher, or find it by searching the TrenItalia schedules and clicking on the Details tab to the left of the specific listing.)

ViaggiaTrenoMobile is designed for web access from your cell, smart phone, or Palm. Enter the specific train number to display is current status. I just found a friend’s train due to arrive at 3.32 from Rome would be 15 minutes late.

Take some time to explore the site to see what other information you might find. Greatest invention since Ticketless!
