The 61-4492 model car is made on the basis of coaches with sleeping berths  built by Tver Carriage Plant, however the interior design has been modified.  Interior design of a coach is created in cooperation with leading Italian industrial and transport design company ItalDesign-Giugiaro. The share of domestic components is above 90%. 

The new coach is equipped with air conditioning system, eco-friendly toilets, Wi-Fi access, display boards and energy-saving lamps. Coaches have hangers and a special luggage space. Air-tight gangways and slack-free couplers reduce noise and vibration while train running. Entrance sliding-plug doors with automatic steps enable passengers to get off both from high-floor and low-floor platforms.

Two types of coaches with seats are produced: business class and economy class. Business class coach has 58 seats with 2+1 arrangement and a VIP-compartment with a convenient two-seater sofa. Economy class coach seats 102 passengers.

After all test cycles and receipt of a compliance certificate, Tver Carriage Plant will deliver 15 double-deck coaches with seats to Federal Passenger Company: five business class coaches and ten economy class coaches. It is anticipated that the first delivery will take place in the second quarter of 2015.
