In 2009, TVEMA developed and manufactured the first vehicle of the MFV project. This multifunctional vehicle provides Quality and efficiency in the servicing of track and infrastructure facilities and hence ensures a high safety level of railway traffic. The railcar is currently successfully operated in several railways of OAO RZD (Russian Railways).

The innovative, state-of-the-art Technologies from domestic and external manufacturers were applied in the design and development of the MFV railcar. The railcar is manufactured using special materials and coatings, ensuring operational comfort for work crews, while not compromising operating economy.

The digital control panel in the driver cab allows for the elimination of copper conductors with aging insulation. Innovative software and integration with traffic control systems dramatically improves operational safety. An instrument compartment and workshops are provided for the work group, and comfortable lounges, a canteen and a shower compartment equipped with suitable proper furniture and appliances contribute to the crew’s comfortable leisure. The railcar is equipped with a micro-climate control system and automated fire-fighting system respectively for the engine and the premises. The railcar’s systems and equipment, including the MTU diesel generator, cause very low noise and vibration in any part of the railcar at travel speeds up to 120 km/h. An MTU Power Pack serves for the electric traction motors of the railcar and for the power supply of all power consumers on board. To ensure the most efficient employment of vehicles in the MFV project, TVEMA offers several versions of this railcar. 

Diagnostic railcar

One of the primary functions of MFV railcars is to serve as a platform for the installation of any combination of various diagnostic systems. These are: systems for track geometry measurement, systems for ultrasonic and eddy-current testing, 3D laser scanning systems, GPR, etc. Various options for the railcar’s layout are offered to facilitate the selection of the proper railcar configuration for each particular task. 

System of secondary diagnostics and urgent repair

The version for secondary diagnostics and urgent repair is ready to handle the tasks of reliable confirmation and repair of infrastructure facility malfunctions, which have been detected. To transport the mobile repair crews the system has a passenger room with 15 seats. To support crew operations, it has an equipped workshop compartment. To support crew operations, the system has a set of the necessary manual equipment for reliable secondary diagnostics.

 Inspection railcar

The inspection railcar is equipped with video inspection and monitoring systems, as well as with other equipment required for inspections, which are conducted by officials of the railway companies. The railcar ensures the most comfortable conditions for operations. 

Geological railcar

Often diagnostic techniques are not enough. Therefore, the instrumental technique is offered – the drilling rig. The vehicle for comprehensive probing and diagnostics of the ballast bed and roadbed of the track by geologic engineers is equipped with a telescopic crane, which is mounted on the cargo platform, with a drilling rig and a set of drilling tools.

 Passenger/cargo railcar

Passenger/cargo rolling stock is intended for comfortable transportation to the work site of large track repair crews numbering up to 50 persons. The railcar is equipped with household utilities for catering and hygienic needs.

Further equipment is: a cargo platform where a telescopic crane is installed, detachable implements and tools for hoisting and track management purposes.
