The ATM Class 4900, Nicknamed the "Jumbotram" is a series of articulated trams used by the ATM on the Milan urban tramway network.

Starting from 2008, some units were equipped with an air conditioning system, while in 2011 the 4950 car underwent both an aesthetic and functional revamping in order to gradually revamp the series.

After a long phase of tests and checks conducted by the company operating the tram network, ATM, in 2014 this unit entered service and by mid-2015 another 19 revamped units were delivered by the AnsaldoBreda company.

[1] In 2023, the cars which were not subject to the previous revamping still in service were repainted with Milan's yellow tram livery, which gradually replaced the original "arancio ministeriale" color scheme, so as to match the coloring of the other trams in service.
