They were projected in the 1950s as an articulated version of the series 5300; originally a series of 15 cars (to be numbered from 4601 to 4615) was foreseen, but the two last units were delivered in an experimental "all electric| version and, because of that, were numbered in the 4700 series. Some years later a second series of "all-electric" cars was built, numbered from 4716 to 4733, and bringing the total number of 4700-type cars to 20 vehicles. [1]
Originally, the cars were painted in a two-tone-green livery, later repainted in the orange livery, and since 2010 in a white-and-yellow livery.
Beginning from early 2017, the 4700 series were gradually revamped, with flooring, sections of the chassis and interior furnishing being replaced. Air conditioning was also implemented. [2]
On the 25th of February 2025, after years of slow retirement due to the ageing of the fleet, the last 4600 was removed from service. [3] The 4700 series persist and are still in service.
