First developed in the early 80's, the Twinstack was the first double stack car to become popular with a number railroads. The five unit articulation concept was used to reduce weight and coupler slack.
 
The models feature five articulated platforms decorated for prototype owners of the cars. Detailing includes etched-metal walkways applied on injection-molded plastic bodies. Cars come equipped with Micro-Trains(R) magnetic knuckle couplers. Each platform can accommodate double-stacked Deluxe Innovations intermodal containers (sold separately). Cars are ready-to-run and include a fitted storage box.
