I am looking for a train schedule in order to purchase train tickets from Florence to Pisa and ItaliaRail states that a schedule is not presently available. I also need to purchase train tickets from Pisa to Riomaggiore, and from Riomaggiore to Rome. Is ItaliaRail the right source to use or should I be using another ticket sales source? I was able to purchase tickets from ItaliaRail for the Venice to Florence leg ot the journey. Thanks.
