The HRCS2 is a multiple unit procured by the Ukrzalisnyzja , which is used especially in express train traffic on networks with 3 kV direct current and 25 kV 50 Hz alternating current . The train was manufactured by the Hyundai Rotem company from South Korea and ten copies were obtained from Ukrzalisnyzja as part of the 2012 European Football Championship . In everyday use, the vehicles showed some major defects, which meant that no further deliveries were made from the manufacturer.
history
The vehicles were procured by the Ukrzalisnyzja to ensure the transport of passengers between the cities, which were integrated into the game operations at the 2012 European Football Championship . The value of the contract is the purchase of these ten electric trains was 307 million dollars . Originally, this contract also included the delivery of four diesel trains with an additional $ 43 million, which, however, were not redeemed.
From South Korea , the trains to Ukraine were delivered by ship across the Black Sea and were unloaded in the commercial port of Odessa . The HRCS2.002 was the first vehicle to arrive in Ukraine on March 11, 2012. By August 2012, the remaining vehicles had arrived and were put into operation.
Description of the vehicles
The electric trains are intended for the transport of passengers on electrified railway sections with a nominal voltage in the contact network of 3 kV direct voltage or 25 kV alternating voltage with a frequency of 50 Hz . They are intended for express train service on railway lines with a gauge of 1,520 mm and are approved for speeds of up to 160 km / h. Two single-arm pantographs manufactured by LEKOV and a main transformer are installed on each sidecar , each of which feeds the converter of the two neighboring motor vehicles.
Four three-phase traction motors with a nominal output of 250 kW each are installed on each control vehicle or motor vehicle (the traction motors are connected in four parallel groups), which receive the power from the four converters and inverters.
The body of the car is supported on the bogies via pneumatic springs. The seating arrangement is in the 2nd class cars in the scheme 3 + 2, in the 1st class cars 2 + 2. There is a bar in the car with the number 3.
composition
The electric train is composed of two motor / control cars, three sidecars and four motor cars using the following scheme: 01 motor / control car, 02 sidecar (with transformer and pantograph), 03 motor car, 04 motor car, 05 sidecar (with transformer and pantograph), 06 motor car , 07 motor car, 08 sidecar (with transformer and pantograph), 09 motor / control car.
The number of wagons in the network of the electric train is 9 (one unit can temporarily be used as a 6-part unit for relations with the smallest flow of passengers). The plan is to operate two connected trains via multiple controls . The train has 1st and 2nd class wagons, all seats are seats. The 1st class wagons are those with the numbers 2, 5, 8; those of the 2nd class are those with the numbers 1, 3, 4, 6, 7, 9. The total number of seats on the train is 579. The 1st class seats are in the side cars (three cars with 56 seats each ), the 2nd class seats are in the six motor cars. In the first control car there are two parking spaces for wheelchairs.
business
The electric train is operated on the railway lines around Lviv , the Southwest Railway , the Piwdenna Salisnyzja , the Donetska Salisnyzja and the railways around Dnipro . The train circulates daily in the following directions;
- Kiev - Kharkiv - Kiev (morning, day, evening);
- Kiev - Donetsk - Kiev (morning, evening);
- Kiev - Lviv (evening), Lviv - Kiev (morning);
- Kiev - Dnipro (evening), Dnipro - Kiev (morning);
- Kiev - Zaporizhia (morning), Zaporizhia - Kiev (evening);
In the summer of 2013 it also circulated on the route Dnipro - Simferopol (morning) and Simferopol - Dnipropetrovsk (evening).
Incidents
The operation of the Hyundai Rotem vehicles was accompanied by a series of incidents, which on the one hand caused a lot of damage to the reputation of the vehicles and on the other hand required a lot of rework. They are listed here below:
- June 30, 2012 - The morning trip from Kharkiv to Kiev was not performed due to technical reasons;
- July 11, 2012 - Breakdown on the drive from Kiev to Lviv ;
- July 31, 2012 - Breakdown on the drive from Donetsk to Kiev ;
- Oct. 13, 2012 - Breakdown in Lyubotine while driving from Kharkiv to Kiev . The passengers had to transfer to other trains.
- October 31, 2012 - Breakdown on the journey from Poltava to Kharkiv as a result of a pantograph broken.
- Oct. 31, 2012 - Breakdown while driving from Donetsk in Kiev ;
- December 5, 2012 - Due to the icing of the contact wire, three pantographs broke near Poltava on the train from Kharkiv to Kiev ;
- December 8, 2012 - the evening train from Donetsk to Kiev did not arrive due to a breakdown;
- December 8, 2012 - Breakdown approximately at Verkhivtseve on the Dnipropetrovsk - Kiev route ;

- February 14, 2014 - The trip was completely interrupted due to a frame tear.
Causes of the breakdowns in December 2012
The reasons for the numerous breakdowns in 2012 were, on the one hand, organizational problems that arose due to the too rapid introduction of the vehicles in connection with the European Football Championship in 2012 and problems that arose due to the differences between the operational areas in Ukraine and South Korea . The trains showed deficiencies in the braking system, the air conditioning and the compressor system. Some pantograph breaks were due to the icing of the contact lines. There were also problems with the coupling of two trains, where condensation formed.
It turned out, however, that the majority of the breakdowns happened at times when the railway operation is generally a bit more complicated than at the rest of the year, namely in the period October - December 2012. It became clear that the vehicles were obviously not suitable for use in Ukraine were prepared. The manufacturer did provide a test ring, but only for the 1,435 mm gauge . There were also some organizational problems that came to light when the trains were delivered to the depots. There were discrepancies in the assemblies that were used in the vehicles. But only Korean specialists were able to solve these problems.
The manufacturing company undertook to solve the problems that had occurred by January 20, 2013, which was also successful. As of January 1, 2013, there were no more significant accidents. Only on the morning of January 23, the train from Lviv to Kiev broke down . The cause has not been written down. There were also some changes in operation; So the batteries have so far been replaced by those of Ukrainian design, which had properties similar to the original ones. With them was the capacity has been increased slightly, which led to some changes in the electrical equipment. After these modernizations, which were aimed at making maintenance cheaper, there were no more breakdowns on the trains in the HRCS2 series .
