M62 locomotive

Under the manufacturer's designation M62 the locomotive factory supplied Luhansk ( LTS) diesel locomotives to many countries of the Council for Mutual Economic Assistance.

Development

For use with freight trains, the locomotive factory Luhansk developed (Russian: Луганский тепловозостроительный завод, Lugansky teplowosostroitelny zavod, Lugansk diesel locomotive factory; later Ворошиловградский тепловозостроительный завод, Woroschilowgradski teplowosostroitelny zavod ), Luhansk ( Soviet Union, now Ukraine ) based on the 1958 to 1961 built series TE10 ( ТЭ10 ) the Soviet railways SZD ( СЖД ) a six-axle diesel locomotive with diesel-electric drive. Due to specialization agreements, the Soviet Union should take care of the CMEA countries with diesel locomotives from 2000 hp. The first purchaser of the new series should be the Hungarian State Railways ( MÁV ). The provided there series designation M62 was also used to manufacturer's designation of the new series. In the main, the development concerned the adaptation to the Central European loading gauge and the interpretation of the bottom frame to the equipment with side buffers. The head pieces with buffer beams fall on even when the broad-gauged machines supplied.

1964, two prototypes, which delivered to the SZD 01 M62 and M62 02. 1965 began the series delivery to the MÁV. From 1966 also received the Polish State Railways (PKP ), the German Reichsbahn (DR ) and the Czechoslovak State Railways type locomotives M62. The Soviet Union itself was only from 1970 more M62. Later, Cuba and North Korea, and industrial railways were supplied. Deliveries ended with most tracks between 1975 and 1979. Merely Poland and North Korea was supplied until 1988 and 1995 respectively with M62. However, the Soviet State Railways still got to 1994 based on the M62 successor types.

The M62 is designed as a heavy six-axle freight locomotive. The framework is structured as a self-supporting bridge frame consists of two inner main longitudinal beams of double T-beams and two outer longitudinal beams of U- profiles, which are connected by cover plates and the Zugkästen on the front pages. The locomotive body is welded with chamfered profiles and corrugated sheets. The frame of the three-axle bogies consisting of two outer and two inner longitudinal cross members and disposed above the pivot bracket. The hereupon patch with pivot bearing locomotive body is supported with a Abstützrückstelleinrichtung.

The diesel engine of the type 14 D 40, a twelve-cylinder two-stroke engine, was provided by the motor factory Kolomna.

According to the interpretation as a freight locomotive, the M62 does not have a device for heating the trains. Inserts on train service were therefore limited to warmer seasons or required the use of Heizwagen.

A characteristic feature of the M62 is the loud engine noise, which in the GDR to the nickname " Taigatrommel " helped them. The machines supplied without silencer had to be retrofitted in the maintenance workshops so that, later, the muffler installed by the manufacturer.

In Germany, the Czech Republic and Slovakia, the M62 from the service of the state railways are excreted, in all other countries, they are still in use. Some M62, however, were taken over by private railways.

The objective of a single diesel locomotive of 2000 HP class for the CMEA was not achieved. Bulgaria and Romania procured exclusively Romanian diesel locomotives to Poland these were delivered in addition to the M62.

Areas of the M62

The M62 was built largely common to the various countries. Noticeable differences are the large headlights PKP locomotives as well as the head pieces without buffer carrier and with Janney coupling in American height at the Cuban and North Korean locos. Otherwise, screw and SA3 - central buffer coupling are mutually interchangeable. Poland, Czechoslovakia and Hungary procured each additional small numbers in the otherwise typical Russian broad gauge for use in border areas and subsequent broad gauge tracks. Externally broad-gauge bogies on only one brake cylinder per side are originally seen in the level of the central axis. Regelspurig delivered bogies have two brake cylinders per side.

The used machines sold to Korea maintained their clutch shots in European level and in some cases the buffer. These machines are coupled with the adapters used in China.

The following table shows the quantities supplied for individual railway administrations and industrial railways M62. Transformations and conversions are not considered. Some M62 were sold after sorting at the State Railways of private railways, where they are used partly outside their former home country.

In North Korea and Azerbaijan some M62 were converted to electric locomotives.

Related series

The Soviet Union procured only a relatively small number of the original M62, but large numbers of modified series. These are:

• 2M62 - double locomotives from two M62 with only one cab 2522 single units from 1976 to 1988
• 2M62U - improved version of the 2M62, recognizable bogies according to the TÄ109 (130 ff DR), 776 single units from 1987 to 1994
• 3M62U - triple locomotive; 2M62U with additional midsection without cab, 312 single units from 1985 to 1992
• Delivered improved variant of the M62, 40 locomotives only on working railways - M62UP
• DM62 - Military version, also available as a power supply system while driving and when stationary, identifiable by boxes and flaps that cover the ports ( eg under the Lokschildern on the front sides ). These machines run like the BR M62U on the well known from the TÄ109 bogies with Achslagerführungen by Lemniskatenlenker. It was used among other things for the cover of the railway missile complexes RT- 23 » Molodjec ". Machines of this type came later in state railway services.

At the Mongolian State Railways ( MTZ ) were delivered 16 M62M (corresponding M62UP ) and 66 2M62M (corresponding 2M62U ). MTZ acquired circa 2005 11 ex SZD 2M62 were unnumbered as 2M62M. In addition, these series were not exported.
