TWO-CAR DIESEL TRAIN - RA-V >>>

The 731.25 rail bus (RA-V) is designed for passenger transit at railway sections without electrification and also for railways of suburban and interregional service.

RA-V is a train, which always consists of two sections with driver's cabs and a connecting gangway of sealed type. The gangway provides the united internal space. The system of multiple operated units makes it possible to make up a train of 3 RA-Vs. The power-plant, operation systems and the traction drive are mounted under the bottom of the car between the bogies. The torque is transferred to two axles of one bogie.

In RA-V modern technical design and materials are used: the body is made of stainless steel, pneumatic cushioning with floor level adjustment, non-flammable materials, shockproof windshield with heating, special doors, moving out steps which let the passengers go in and out of the train on low platforms.

All units of a monoblock power transmission are attached to the frame by resilient elements that provide high level of vibration resistance.

The equipment of a passenger saloon and driver's cabs with a heating system, forced ventilation, window multiple glass units and reliable heat and sound insulation provides comfort for passengers; and the availability of an automatic locomotive signaling system, dead man controller, on-board information control system, blocking devices operating when the driver passes from one cab to another, automatically opening doors, reliable braking system makes the journey maximally safe.
