TEM2 of later series as this ТЭМ2-7789 built by the BMZ at 1984 y had new design of hood and cab with improved thermal insulation, modernized generator, and electric coolant heating added. Still present old type bogies also had some improvements.
From # 8002 locomotives of this seria were designated as the TEM2U (U means improved).
The long story of TEM2 locomotives started when a small number of the ALCO RSD-1 were obtained by USSR as the Lend-Lease shipments during WW2. They were designated as Da20 (Да20) type of locomotives of Soviet Railways. TE1 (ТЭ1), the first Soviet diesel locomotive built in big series at 1947-50 (298 ones) was in fact the non-lycensed copy of the american ALCO RSD-1 locomotive but in metric scale. TE1 were not excellent as the mainline locomotives, so its next variation, TEM1, were intended to use as shunting locomotives. They were developed on the base of TE1 locomotive and still had many elements of original ALCO RSD-1 design, but with modifications - bogies were significantly improved (especially the technology of its fabrication), also the D50 diesel (metric variant of the ALCO 539T used in TE1 and TE2) was modified to 2D50 (2Д50) version. TEM2 was developed as upgrade of the TEM1 with some modifications made including improved 1200 hp diesel PD1M (ПД1М) - further development of the 1000 hp. 2D50, further modernized bogies with additional coiled springs included etc.
TEM2 (ТЭМ2) shunting locomotives were built routinely at 1960-90 yy primarily by the Bryansk Machine-Building Plant (JSC BMZ located in Bryansk, Russia; Брянский машиностроительный завод). With 6225 total production, 1000 were built in Soviet Ukraine by the Voroshilovgrad Locomotive works, (Ворошиловградский тепловозостроительный завод, ВЗОР, now the Luhansk Locomotive works).
The logo "СИБУР" on this locomotive means it is privately owned by the Petrochemical transport company (ООО «Нефтехимическая транспортная компания»; ООО «НХТК»), that is joint venture of the SIBUR Holding and SG-Trans. The SIBUR (СИБУР Холдинг; PJSC SIBUR Holding) is the largest integrated petrochemicals company in Russia founded in 1995 and headquartered in Moscow. The company purchases hydrocarbons and processes them into plastics, rubbers and other high value added products. The Group sells its petrochemical products on the Russian and international markets in two business segments: Olefins & Polyolefins (polypropylene, polyethylene, BOPP films, etc.) and Plastics, Elastomers & Intermediates (synthetic rubbers, EPS, PET, etc.).
