The new version of the vertical sleeper MU follows the head model of the new generation of CRH2E and CRH2G inspired by the “Horse†and has 16 large groups.
The interior of the train adopts a new layout: In addition to the 9-car WRC, which is still a traditional horizontal-sleeper private room layout, all other cars adopt a longitudinal sleeper design with the berth parallel to the train running direction.
The upper and lower berths have windows, so the upper and lower black bars can be seen on the outside. However, the inside of the train is still a single-story design. There is no need to go up and down the stairs.
At the same time, the head and tail of the vehicle was changed from a second-class seated vehicle to a soft sleeper with a capacity of 40 passengers; the middle-sleeper was increased from 40 in a horizontal sleeper to 60 passengers; people.
The total capacity is 880, which is a 37% increase compared to the previous CRH2E horizontal sleeper version (capacity 642/second seat 55×2/soft sleeper 13×40/meeting sleeper 12).

The ceiling of the passenger compartment is flush with the upper edge of the upper air conditioner and can still meet the vehicle boundary requirements. .
In the book “Design of Variable Marshalling Multiple Units†written by Huang Junhui, we can find an internal design that is almost consistent with the vertical movement that was just off the assembly line.
