The museum contains original engines as well as scale models incorporated into a display of the history of trains in Italy. The displays include the Bayard, the first locomotive in Italy,With the unification of Italy, the construction of steam boilers was taken over by industry in the north and Pietrarsa was relegated to the role of a repair facility. It served in that capacity until the 1970s when the facility was rendered obsolete by advances in diesel and electrical technology.
The Pietrarsa railway museum is in Naples in southern Italy. It is one of the most complete such facilities in the world. The museum is located on the premises of the former metal foundry of the Kingdom of Naples, a plant that produced most of the boilers for locomotives and steam-driven ships in the kingdom in the first half of the 19th century.Further realization that Paget disease was not a rare disorder came about after the discovery of X-rays in 1895 by Roentgen.The museum occupies four large buildings at the old Pietrarsa works immediately alongside Pietrarsa station on the FS line along the coast from Naples to Portici. It was the first railway in Italy, opening in 1839 and the works opened the following year. The numerous steam locos are housed in what looks like an old erecting shop with a traverser running the length of the building with numerous bays on each side. There are a few vintage electric locos there as well. Other buildings house the diesel locos, railcars and heavy engineering machinery. It's an extensive site and the whole place is full of character. There's a refreshing lack of extraneous signage and nearly all the locos are in FS.
