The '''TE2''' ({{Langx|ru|ТЭ2}}; {{Langx|uk|ТЕ2}}) is a class of Soviet diesel-electric locomotives built by Malyshev Factory in Kharkiv, Ukraine, from 1948 to 1955. It is nominally a two-unit version of the TE1, 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.<ref name="Heywood & Button">{{cite book|last1=Heywood|first1=A.J.|last2=Button|first2=I.D.C.|title=Soviet Locomotive Types|year=1995|publisher=Frank Stenvalls Forlag|location=Malmo|isbn=9172661321|page=44}}</ref>

==Powertrain== Each of the two units is powered by a {{convert|736|kW|hp PS|lk=on|abbr=on}} Penza D50 4-stroke 6 cylinder supercharged diesel engine and has four {{convert|152|kW|hp PS|abbr=on}} DC traction motors.

==Production== Prototypes were built in 1948 and 1949 and series production ran from 1950 to 1955.<ref name=rakov379/> A total of 528 pairs was built.<ref name=rakov379>Rakov (1995), p. 379-381.</ref> Each pair carried a single number in the range 001 to 528.<ref name=rakov379/>

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

==TE4== The TE4 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. ''See ТЭ4 at the Russian-language Wikipedia.''

==TE6== The TE6 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.<ref name=rakov379/> They were designed to "meet the requirements of protection against injury factors of a nuclear explosion".
