Train to Siena

[Perserverer]

Is it possible to park free overnight near a small train or bus station outside Siena so I can stay in Siena overnight and collect my car the next day which will stop any parking stress! Really appreciate your help.
I am staying at Marina dei Massa and noted that the train journey from there is very time consuming so I thought I'd drive closer.

You could drive to and park at the Badesse train station which is the last one before arriving in Siena. It is quite small and so trains are not that many, but you could definitely do it that way. Check trenitalia.com to see timetable and plan accordingly.

Otherwise, drive to the train station - there is a large lot there, no where near the ZTL and costs only 2 euro per day!
