Metrorail uses 136 heavy-rail cars (known as the Universal Transit Vehicle) built by the Budd Company under the name "Transit America"; they are identical to those used on the Baltimore Metro SubwayLink (save for the modifications made to Baltimore's cars during their refurbishment between 2002 and 2005), as the two systems were built at the same time, and the two agencies were able to save money by sharing a single order.
The Baltimore-Miami order was among the last orders Budd filled before shuttering its railcar manufacturing business; a fleet of similar vehicles was manufactured by Società Italiana Ernesto Breda for the Red and Purple lines of the Los Angeles Metro Rail between 1988 and 2000.

These cars were manufactured in Budd's Red Lion plant in Northeast Philadelphia in 1983.
The cars are 75 feet (23 m) long, 10 feet (3.0 m) wide and have a top design speed of over 70 mph (110 km/h).
They are semi-permanently attached in married pairs, and joined up to form 4-car trains, which is the normal train length.
Each car can hold up to 166 passengers (76 seated, 90 standing), and draw power from an electric 750 volt third rail.
