[4] The Brookville Liberty Modern Streetcar is equipped with 750 V DC onboard battery packs made up of rechargeable lithium-ion batteries, referred to as an onboard energy storage system (OESS), that enable it to operate off-wire.

[6] Brookville president Marion Van Fosson referred to it as "the Prius of the modern streetcar market" due to its hybrid design that allows it to run on either battery power or via pantograph and catenary wires.

[8] The streetcar is a 70% low-floor design that measures 66.5 feet (20.27 m) in length and can seat 32 passengers; it is also capable of accommodating between 125 and 150 people while fully loaded.

[4] The streetcar rides on Brookville's Soft-Ride trucks on standard-gauge track, and can reach a top speed of 35 to 44 miles per hour (56 to 71 km/h).

[13] In November 2015, Milwaukee signed a four-car, $18.6-million contract with Brookville for its Lakefront Line, the third order for the streetcars.
