Locomotives series M62 | “GTRZ” PJSC

The locomotive was built at the Lugansk Diesel Locomotive Plant and initially supplied only to the socialist countries. In Poland, he received the ST44 index, in the GDR, first the V 200, then the BR 120, then the BR 220 (change of the unified classification), in Czechoslovakia T679.1 – then changed to 781, in the DPRK – K62, in Cuba – 61.6. The locomotive was also supplied to the MNR in a two-section version under the symbol 2M62M.

In the new machine, much has been borrowed from the design of diesel locomotives TE10 (trolley, power scheme, circuit drives of auxiliary units). Thanks to the successful layout and some other design features, the machinists were very pleased with this diesel locomotive. . Among the shortcomings that emerged during the operation, we can single out the small capacity of the fuel tank – 3800 l. This disadvantage, of course, migrated to 2M62, only in version U the fuel tank became larger – 7300l. Since 1970, diesel locomotives of this series (from number 1003) have been built for operation on the 1520 mm gauge railways of the Soviet Union. Part of the locomotives built for the Soviet railways were intended for use on a 1,435 mm gauge in the border areas. A total of 721 cars were built.

Modifications

2M62 – a two-section version of the M62, 1976, came to replace the obsolete TE3. During production, changes were made to the structure, in particular, from the 751st number, it was manufactured with block buffer lanterns. Issued in the amount of 1261 diesel locomotive.

2M62U – two-section year 1987, with jawless bogies, increased fuel tank capacity and block buffer lights (393 cars produced, not including exports).

3M62U – three-section year 1986, with jawless trolleys and block buffer lights (104 pieces were produced). Often (especially after overhauls) work only in two sections.

DM62 – one-section, 1982-1994. Used as part of combat railway missile systems (BZhRK) of the Strategic Missile Forces Molodets; Each of the trains BZHRK equipped with 3 diesel locomotives. It differs from the “base” M62 in a number of changes designed to increase the reliability and “survivability” of a diesel locomotive, some of which were later used to create the 2M62U. Externally, it can be distinguished from the usual M62 by jawless trolleys, block buffer lights, partitioning, communication and control panels (MSS – “boxes” under the frontal number plate), adjustable path wiper. The letter D was not placed on the number plate (if it is now, then it is a local initiative). A total of 154 cars were built. After the dissolution of BZHRK, all diesel locomotives were transferred to the general use railway and to industry for normal operation.

M62UP is actually a single-section version of 3M62U. Used only in industry (mainly in Ukraine). Issued 40 pieces.

3M62P – three-section, 1988. Locomotive for the launch vehicle launch to the launch site of the Baikonur cosmodrome. Initially they were three-section, but the third sections were not used from the very beginning and were written off. In total, they were released three, as previously three TE3P, and the number 0003 (after the collapse of the USSR) was converted into the usual 2M62U with the assignment of the number “0394”, and remained in Ukraine. The numbers 0001 and 0002 were not used for a long time, partially dismantled and in 2012 put up for sale.

2M62M – two-section for the Ulan-Bator railway. They are adapted for semi-desert conditions of Mongolia and have a modified design of cleaning the air supplied to diesel engines from sand and dust. In total 60 diesel locomotives 2M62M were built.

Upgrades

The diesel locomotives of the M62 family, which have exhausted the engine life of a diesel generator set, are being upgraded. In most cases, the two-stroke diesel engine 14D40 is replaced by a four-stroke 2D49 (2000 hp). Such diesel locomotives are easily recognizable by the air filter jutting out into a “cross hump” on the roof. Sometimes they get a new series: М62К (in Lithuania), 2М62К (Russia and Belarus, Lithuania), 2М62УК (Russia and Belorussia), 2М62UR (Latvia).

In Hungary, Latvia and Lithuania, some diesel locomotives under overhaul (KR) and modernization received Caterpillar diesel engines, more powerful than the previously installed 14D40. Such locomotives were assigned new series 2M62US and 2M62UM (Latvia) or 2M62M (Lithuania).

In North Korea, part of the M62 series of diesel locomotives was converted into electric locomotives. Also in Azerbaijan, the 2M62U-0168 was converted into an electric locomotive using electrical equipment from an electric locomotive of the VL8M series. In 2017, the company VIS Systems commissioned Rail Polska to upgrade the section of the 2M62U-1006 diesel locomotive to the 207E-001 electric locomotive.
