I'm confused about Eurail trains! How do I reserve the trains?

Question

It says on the Eurail timetable that I need to reserve the trains. I got my Eurail pass ticket already and waiting for it through the mail. Is there supposed to be a website or phone number so I can reserve the trains? More specifically trains I'm looking at that need to be reserved:

1) Toulouse, FR to Nice, FR

2) Nice, FR to Venezia, IT

3) Venezia, IT to Pisa, IT

4) Firenze, IT to Rome, IT

5) Paris, FR to Toulouse, FR

Answer 1

You need to make a reservation on the train at each specific station -- show them your Eurail pass and you won't have any problems.
