Tags: Railway Line.
Tramway line T3 is the first modern tramway in Paris proper since the 1937 closure of the previous comparable system. It is operated by the Parisian Transport Authority (RATP: Régie autonome des transports parisiens) and is divided into two sections called T3a and T3b. The line is also known as the tramway des Maréchaux because it follows the boulevards des maréchaux a series of boulevards that encircle Paris along the route of the former Thiers Wall (built 1841–44).
