They were built from 1976 to 1978 in two series, by Fiat Ferroviaria and Stanga, respectively, and were intended to be used on the future light rail lines, like the proposed circular line that should substitute the existing circular trolleybus line. However such lines were never built, and the 4900 were used on the existing network. == Bibliography == * Carlo Marzorati: ''Le nuove elettromotrici ATM 4900.''
