CRRC Tangshan says the modular CRH3X train can be freely configured in response to passenger demand, unlike its current generation distributed power high-speed trains, which operate in fixed eight or 16-car formations.

Traction systems, train control systems and couplings have been configured to simplify the removal and insertion of individual vehicles.

The restaurant car is equipped with freight compartments in the lower deck to carry insulated and refrigerated containers. The train has also been designed to accommodate small freight containers.

CRRC plans to offer the train in 160, 250 and 350km/h variants.

The company says it has applied nearly 80 patents in the development of the train.
