M62 is a Soviet-built diesel locomotive for heavy freight trains, exported to many Eastern Bloc countries as well as to Cuba, North Korea and Mongolia. Beside the single locomotive M62 also twin versions 2M62 and triple versions 3M62 have been built. A total number of 7164 single sections have been produced, which have been used to build 5231 locomotives.

According to the Comecon directives production of heavy diesel locomotives among Eastern Bloc countries was left exclusively for Romania and the Soviet Union. The first few prototypes of this heavy freight locomotive were ready in 1964 and their first destination outside the Soviet Union was Hungary. A total number of 723 units were produced in the Soviet Union.

From 1970 till 1976 the former Soviet Union Railway (SZhD) received 723 engines M62, further 13 M62U have been delivered from 1989 till 1990. These engines were single 3M62U sections.

For the Soviet military 154 locomotives named DM62 were built. These engines have been modified for pulling SS-24 Scalpel ballistic rocket launcher trains.

For industrial railroads 39 engines of the version M62UP have been built . These engines had improved trucks, larger fuel tanks and modified exhaust silencers.

In the early 1960s an urgent need appeared in Poland for a heavy freight diesel locomotive. The Polish industry at the time was not able to produce such a locomotive, so a decision was made to import a large number of M62 locomotives from the Soviet Union, which were already imported by Hungarian MÁV. In Poland those machines received ST44 designation During first-revision repairs all locomotives had front lights changed from small ones into standard, Polish large types. The decision is said to have been made after Poland had started to import ST43 locomotives from Romania and was probably influenced directly from the Soviet Union. For political reasons, the USSR simply forced Poland to buy Soviet instead of Romanian locomotives, as it preferred satellite countries not to export their products. The first 4 locomotives, produced by the Voroshilovgrad Locomotive Factory (in today's Lugansk, Ukraine), were delivered to Poland in September 1965. Deliveries continued until 1988, with 1,191 locomotives delivered in total (1,114 for PKP, 68 for LHS and 9 for industry). One of the locomotives (ST44-1500 – producer’s designation M63) had bogies and traction engines exchanged with newer types which allowed it to achieve a higher top speed. The series, with numbers between 2001 and 2068 was imported to run on the LHS broad gauge line. In addition to a different gauge, this series was equipped with an automatic coupling system.
