Diesel multiple unit DPKr-3

DPKr-3 (Dizel-Pоizd Kryukovsky, Type 3) — is a regional diesel train manufactured by the Kryukiv Car-Building Plant. So far the only copy, built in 2019, ran between Kyiv and Boryspil Airport on the Kyiv Boryspil Express route until September 2020, when it was relocated to the route T. Shevchenko station (Smila) - Cherkasy, serving an express line.

Technical characteristics

Engine

The regional diesel train DPKr-3, like its predecessor DPKr2, has three cars. The two extreme cars are motorized, and are equipped with engines with a capacity of 588 kW.

The main motor cars of the diesel train are equipped with a modular diesel-hydraulic engine Voith RailPack 600 DH, located in the cars' underbody space. Manufactured by the German Voith company,[1] it consists of a jointly-developed diesel engine Voith V2862T3, a MAN Truck & Bus for use on diesel train cars, and hydrodynamic transmission Voith T212bre, as well as an electric generator to power the train's electrical systems. The total length and width of the installation is 3707 × 2800 mm.[2]

The V2862T3 diesel engine is four-stroke, 12-cylinder, V-shaped with a cylinder camber angle of 90° (45° to vertical). The engine is equipped with a system of selective catalytic neutralization of exhaust gases (SCR) and meets the IIIB environmental standard for exhaust emissions. Rated engine power - 588 kW at a speed of 1800 rpm; maximum torque - 3350 N • m at a speed of 1300-1500 rpm; working volume - 24.24 liters (12 × 2.02 liters); maximum average effective pressure - 17.4 bar; length, width and height - 1667 × 1644 × 859 mm.[2]

The hydrodynamic transmission T212bre transmits traction from the engine to the wheelsets of the drive cart through the turbine oil without a continuous rigid connection in traction mode, and separates them when the train is parked or running without traction. It is connected to the engine by a common flange and has one torque converter and two hydrodynamic clutches, which form three circuits of oil circulation, a hydrodynamic brake (retarder) and a mechanical reverse to change the direction of movement, as well as an automatic electronic control system. Switching of steps is carried out automatically by filling one circuit of circulation with oil, and emptying another. Nominal input power of hydraulic transmission - 450 kW; oil supply - 95 l, maximum torque - 1200 N • m; length, width and height of hydraulic transmission - 1070 × 1055 × 756 mm.

The cooling unit of the engine, which in the previous diesel train was located in the undercarriage space, was moved to the roof of the main cars. This arrangement of cooling units will reduce the likelihood of dust, debris and dirt getting into the radiators, which are raised by air currents from the railway tracks during movement.

Power supply of the intermediate, non-motor car is carried out from two generators located on the main cars.

Interior

The train's predecessor, DPKr2 was developed as a suburban train, containing 283 seats of the third class, a lot of free space for standing passengers. The regional diesel DPKr3 contains less, only 170 places, but with an increased level of comfort, and an added first class section.

Each car has two vestibules, between which are the seating areas. The sanitary module / steward's compartment can be accessed from the front vestibule of the main car.[3]

In one of the main cars there are 58 seats of the second class according to the 3 + 2 scheme, and a steward's compartment. In the other main car there are 51 second class seats, space for wheelchairs, an enlarged sanitary module for passengers with disabilities. Seat width in the widest sections is not less than 450 mm. Between the seats there are armrests and power sockets.[3]

The intermediate car is more spacious, with 61 first class seats according to the 2 + 2 scheme, and a sanitary module. Seat width in the widest section is not less than 490–500 mm. They have wide comfortable armrests and individual sockets with a USB connector. The section is equipped with screens for entertainment.[3]

Operation

It was expected that the new diesel multiple unit will be based at the depot Ternopil, as part of the Lviv Railway in the fall of 2019.[4]

However, on December 27, 2019, the train was assigned on the route Kyiv Boryspil Express.[5][6][7] Due to the sharp reduction in passenger traffic during the coronavirus pandemic, and limitations of international air traffic, in March 2020 UZ temporarily suspended its operation.[8]

On September 9, 2020, the diesel train was sent from Kyiv for a run-in in Smila (T. Shevchenko station of the Odessa Railway).[9] On September 11, the manufacturer Krukivsky Carriage Works announced results, pointing to a number of technical shortcomings of the railcar depot TC-5 of the Odessa railway, selected to maintain the DPKr-3-001 train.[10] Krukivsky announced the need to find another route and service provider.[11] This statement was amended in their next press release however, stating that the depot needs to be prepared for servicing the train, and that on September 17 another test run was organized. It was also announced that by September 26, all the discrepancies of the depot indicated by Krukivsky specialists should be eliminated in full, and commercial transportation of passengers in this direction of traffic can begin right after.

DPKr3-001 at Cherkasy station

Before entering regular operation, the train's technical condition was verified and rail workers performed maintenance. In Kyiv, training of Odessa Railway locomotive crews was organized by Krukivsky specialists. As a result of the run-ins, the route, schedule and other traffic parameters were worked out.[12]

On September 23, 2020 DPKr-3 went on its first regular trip as a regional train No.805 connecting Cherkasy and T. Shevchenko stations.[13][14]

From September 24, the train performs 8 daily runs between Cherkasy and Smila, numbered No.803/804, 805/806, 807/808, 809/810. Only one pair of trains, No.803/804 make an intermediate stop at Smila station, others run non-stop. The schedule allows passengers from Cherkasy to change to a number of passenger and high-speed trains, including Intercity, which stop at the Taras Shevchenko station and go not only to Kyiv, but also in other directions. As the new trains were classified as regional, the ticket price is higher than the suburban ones. The cost of tickets varies from 25 to 30 hryvnia (second class) and 70-80 hryvnia (first class). On weekends the price is somewhat higher.[12]

The diesel train is serviced in the T. Shevchenko (RPD-5) motor car depot, which is structurally subordinated to the motor car depot Khrystynivka (RPC-6) of the suburban passenger transportation department of the Odessa Railway. The work of the train is monitored by the Kyiv department of Krukivsky Carriage Works.[12]
