I am trying to purchase tickets on the Eurostar from Florence to Rome. The station of departure for June 29th on the Trenitalia web site is as follows:

9:53 a.m. FI.SNN (Santa Maria Novella)
10:10 a.m., FI.RIFR (does this indicate the train stops somewhere?) I can't figure out what the letter represent.

I prefer to take the 10:10 a.m. train.

Oops typo: I meant to type
9:53 a.m. departure from FI.SMN (not SNN)

Hi I,

The 10:10 does not depart from the SMN station. It leaves from the Rifredi station.

Get up 17 min earlier and take the 09:53.

Florence has 2 train stations; the SMN is easier to get to and probably whay you want.

florence has three large stations - Santa Maria Novella - the central station, a dead-end terminus in the heart of town, and Rifredi a few miles north and Campo di Marte, which is fairly close to town, being just about a mile east of the center.
Some trains do not go into the dead-end SM Novella station but take the mainline route around Florence, stopping only at Rifredi and Campo di Marte - point is if a train serves Rifredi it may as well stop at Campo di Marte, which is much closer to many hotels than Rifredi, which is much farther out of town. Campo di Marte is also a sleepy station much more leisurely to manage than hectic SM Novella. There are trains every few minutes between SM Novella and Rifredi but as Ira says there are plenty of trains that serve SM Novella - it's the odd one that doesn't.

Thank you, thank you. I would have made a huge mistake if I booked the 10:10 a.m., so the 9:53 a.m. is the one we want for Rome.

Arriving from Venice at 10:30 I wish to take the 11:00 (train #3151) to Pisa. What is the route and proximity from deboarding the Eurostar Italis to boarding the local train to Pisa?

Thanks...

Florence SMN train station consists of about 15-20 or so parallel tracks, all lined up in a row and all dead ending at the station.

The route is that you get off the train from Venice, walk to the head of the train, find out which platform your Pisa train departs from (posted on the sign boards), validate your Pisa ticket in a yellow machine (very important), then walk to the departure platform.

The proximity of the tracks is all quite close. The walking distance will depend more on where your seat is located on the incoming train.

IIRC the regional trains depart from the far left side of the station (if you are facing the train tracks), but I could be mistaken.
