Livorno-Pisa-Florence-Livorno

Steph, I'm assuming you are doing all of this in one day? If you buy a regionale ticket from Livorno to Florence, you can get off at Pisa. The only catch is that once you validate your ticket, you have 6 hours to complete the journey. (You may get away with more than 6 hours, but that is technically the rule - if the conductor is strict he can enforce it with a fine.) Therefore, you would only have a few hours in Pisa. In my opinion, that is plenty! You can either walk to the Leaning Tower (will probably take you about 30 minutes each way) or take a bus from the train station. Then get back on the train and continue onto Florence where you will have more to see anyways. Then buy a ticket for the return trip (or you can buy both at once).

I'll give you a conditional answer of YES, you can do this. However, here are the conditions of my answer. With the Trenitalia's new website format, it is so unfortunate that they have removed all information on the intermediate stops of the train run. Shame on them. I can see them on the German www.bahn.de website. The German website does show Pisa as a stop on the run from Livorno Centrale to Florence. Since these runs are 1) mostly on Regionale trains and, 2) require no train changes, the conditional answer is still yes. Here are further conditions. 1) you must do this on the Regionale trains. You cannot do this on the InterCity or Eurostar trains that do stop at Livorno Centrale and do go on to Pisa Centrale. 2) when you buy a ticket on a Regionale train, its good for 60 days. It will not show a specific departure date, departure time and it will not have any seat requirements. Perhaps its like your bus up to Keswick. The ticket is good for any Regionale train making the run shown on the ticket for 60 days. 3) Here's the wrinkle. Once you validate the ticket in the little yellow machine in the train station, the ticket is active and is good for 6 hours. 4) your overall journey time to Florence is 1hr40min. Thus, you have 4hrs20min to jump off the train at Pisa Centrale, go see the Leaning Tower and get back on another Regionale train to Florence. Yes, the Regionale Veloce train qualifies as a Regionale train. You must complete your entire journey within the 6hrs. Again, these are the conditions assuming that the runs are still what I see on the German website. No guarantees. Here's a link to what I see. http://gyazo.com/88646d52f02e54b0079b6649b6dd173c
