Each train features one Intermediate Car and two Power Dome Car locomotives. For speed and reliability, both engines are powered with a new and improved drive system, and both have sound decoders (sounds include turbines, bell, doors, station announcements and the unit's distinctive horns, all taken from prototype recordings) and speakers. Additional Intermediate Cars are available to make a longer train. Several different Coach, Cafe and Club cars are available (including the newly tooled coach with additional baggage space) depending on the choice of paint scheme. The TurboTrain operates with or without sound on both DC and DCC.
The models are fully prototype-specific, with three different Power Dome Car designs represented and six Intermediate Car styles available. Minimum radius is 18" without diaphragms, 24" with diaphragms. Note, parts from the 2022 train are not compatible with the original 2008 release.
