florence to sienna to rome

Bus from Florence to Siena is better than train as the bus gets you into the town, train station is outside of town.
Train from Siena to Rome then train from Rome to Florence.

Thank you for this information. When I looked at train schedule from Sienna to Rome, it looks like it takes 3.5 hours and some connections go back to Florence. Would it be better to take bus from Sienna to Rome?

Just FYI. The train station is not that far from the center of town anymore. Hasn't been for a few years. There's an escalator that goes from the shopping mall across the street from the train station to just outside the walls. We spent over a week in Siena and used it a few times for parking and train day trips. If the train schedule works in your favor, I'd consider.
