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.

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.
