ACOTRAL MR 300

The MR 300 was a rapid transit rolling stock type operated by STEFER and later ACOTRAL on the Termini-Laurentina Metro, later known as Line B of the Rome Metro, and later the Rome-Lido Railway from 1976 to 2009.
==History==
The MR 300 was the second batch of rolling stock in operation on what would become the Rome Metro. A total of twenty-four cars were built, numbered MR.301 through MR.324; the car's bodies and other mechanical portions were manufactured by Officina Meccanica della Stanga, their bogies by TIBB and their electrical systems by CGE. The cars were manufactured in 1976 and entered service the same year, complementing the MR 100 and MR 200 trains already in service on that line since the 1950s. The line was renamed Line B in 1980 with the opening of a new line from Anagnina to Ottaviano, named Line A.
Beginning 1987, the MR 100, MR 200 and MR 300s were replaced with MB 100 trains on Line B; following further modifications and modernizations to the line, the three train types were fully replaced with the MB 100 with the line's modifications preventing them from running on Line B. The trains were then moved to the Rome-Lido Railway, where they operated until about 2009.
No MR 300s have been preserved.
==Design==
The MR 300s featured similar design elements to the preceding MR 100 and MR 200 cars that came before them but were more modern an up to date, featuring equipment similar to that of the MA 100 trains intended to be used on what would ultimately become Line A.
Each car is coupled in two-car sets although four- to six-car consists were generally used on Line B.
==Specifications==
The MR 300 used a CGE-manufactured rheostatic control system. The sets ride on Brill bogies manufactured by TIBB.
