Housed in an historic station, this museum not only covers rail history in this area, but also general history of Naples. Parking and entry are free and easy. Though the information is great, it does have a lot of reading. Displays are well presented. Took us a little over an hour, but we read everything. On weekends there is a small train that circles the building which children love to go on. Definitely worth a visit, particularly on a rainy or cold day.
