The TE2 (Cyrillic script: ТЭ2) is a class of Soviet diesel-electric locomotives built by Kharkov in Ukraine from 1948 to 1955. It is nominally a two-unit version of class TE1 (ТЭ1) but is very different in appearance. While the TE1 is a Co-Co hood unit, the TE2 is a Bo-Bo+Bo-Bo cab unit.[1]


Each of the two units is powered by a 736 kW (987 hp; 1,001 PS) Penza D50 4-stroke 6 cylinder supercharged diesel engine and has four 152 kW (204 hp; 207 PS) DC traction motors.


Prototypes were built in 1948 and 1949 and series production ran from 1950 to 1955.[2] A total of 528 pairs was built.[2] Each pair carried a single number in the range 001 to 528.[2]


TE2-414 is preserved at the Museum of Railway Technology, Saint Petersburg.


The TE4 (ТЭ4) was an experimental modification of a TE2, designed to run on solid fuel by using a producer gas system. The gas generator was mounted on a four-axle non-powered unit, placed between the TE2 power units, making a wheel arrangement of Bo-Bo+2-2+Bo-Bo. It was not a success and was converted back to a TE2.

The TE6 (ТЭ6) was a class of sixteen TE2-type locomotives ordered by the Ministry of Defence in 1952. They were single-section and their purpose was to serve as locomotives or mobile alternating current generators.[2] They were designed to "meet the requirements of protection against injury factors of a nuclear explosion".
