TEM2-162 owned by ZIK engineering company, Sandomierz, November 5, 2017.
In July 1958 prototype TEM1 diesel switcher was outshopped from Bryansk Engineering Works (BMZ); in Soviet designation system T stood for diesel, E for electric transmission and M for switcher. Origins of this locomotive can be traced back to the RS1 four-axle (Bo’Bo’) diesel, developed by ALCO in the USA. Its axle load of almost 30 tonnes conformed with American mainline standards, but nonetheless was comparatively high. Therefore during the war, in order to provide a locomotive suitable for Lend-Lease deliveries to other countries, a six-axle version was designed. Contrary to the locomotive developed in parallel along the same lines by Baldwin, whose six-axle variant was in fact a new design, ALCO machine, designated RSD1, was a RS1 married to new three-axle trucks. During WWII RSD1 was built in rather small numbers (probably not more than 150 units).
Soviet railway specialists, involved in procurement of class Ea steam engines in the USA, suggested that American six-axle diesels might be well suited for mainline service in the USSR. Both Baldwin and ALCO locomotives, obtained via Lend-Lease, were considered. RSD1 was the first to arrive, although deliveries started when war in Europe was ending. In all, 68 machines of this type were supplied to the USSR in 1945 (of 70 dispatched; two were lost en route with sunken ships). They were classed Da20, or Дa20 in Russian script, which was shortened to Da in 1947. Baldwin locomotive (designated Db) was initially plagued by prime mover failures and deliveries began only in 1946. History has it that, when in 1945 a Soviet government train was hauled to Potsdam by a RSD1, Stalin was delighted by its faultless performance. No wonder, thus, that in 1947 its copy, was put into production at the Kharkov works as TE1-20 (TЭ1-20 in Russian script). It was soon shortened to TE1. Db and indigenous T17 (designed in 1938, but later shelved) were rejected, although both were better suited to mainline service. In all, 300 TE1s were built until 1950, including a variant for extremely cold climate, designated TE5. In the mainline service they were soon replaced by more powerful types, but TEM1 switcher, developed from them, was much more prolific: when its production was halted in 1968, 1946 machines had been built. In 1959, however, it was decided that more powerful switchers were also necessary, and Bryansk design team developed the TEM2; this designation indicates that electric transmission was retained, although it had been suggested that for such machines hydraulic transmission was more appropriate. Between 1960 and 1963 only a few examples were built, large-scale production starting only in 1968. In 1969, Voroshilovgrad (now Lugansk) factory also commenced production of this type, eventually contributing 1354 examples to the total output.
2D50 six-cylinder in-line diesel (developed – some say directly copied – from McIntosh & Seymour type 539 used in RS1 and RSD1) of the TEM1 was replaced by its development PD1 with 20 percent more power. Both were built by Penza diesel engine factory. In 1968 – soon after the type had been ordered in quantity – it was replaced by the PD1M with the same rating, but longer service life and slightly lower fuel consumption. Economy, however, has never been the strong side of this locomotive, at least by current Western standards. Other modifications were also progressively introduced during the production run, which continued until 2000. Principal variants were TEM2 (1960 – 1984, 6219 examples), TEM2U (1978 – 1989, 1390 examples, with more angular body and lower roof-mounted spark arrester) and TEM2UM (1989 – 2000, 1078 examples, new 1-PD4A diesel-generator unit, a de-rated variant of 1-PD4). TEM2A was a version of TEM2 or TEM2U that facilitated easy conversion to 1435 mm track, while TEM2AM was an equivalent variant of TEM2UM – production figures for Soviet/Russian operators are included in the above numbers. TEM2M, which appeared in 1974, featured new 6D49 eight-cylinder diesel engine (the same rating – later used in the TEM5) and was built until 1988 in relatively small numbers (286 examples).
Experimental variants included TEM2US with electromagnetic device for adhesion improvement (1978, one), TEM2T (1983 and 1985, two) and TEM2UMT (1990 – 1991, five) with electrodynamic braking, TEM2UM (1988, one) with 1-PD4 diesel-generator unit rated at 1350 hp, which failed to reach production status, and TEM2UMM with microprocessor control systems (1992, one). This gives a total of 8983 examples (the above statistics have been based on data provided by Vyacheslav Sokolov, available at http://scado.narod.ru) built for Soviet and Russian operators. Since 2002, 125 TEM2s and TEM2Us were modernized to the TEM2K (or TEM2-K) standard, with 1-PD4D diesel engines, rheostatic braking and many minor refinements; TEM2AK is the equivalent modernization of TEM2A (31 examples). TEM2M of 2005 is a modernized variant developed by the Chelyabinsk works, of which little is known. Currently OAO Kolomenskiy Zavod company offers 3-3DG power-packs which, compared to PG1M, are lighter and offer specific fuel consumption reduction by about 5%.
These locomotives were also built for export. TEM4 was a tropicalized version for Cuba, with the de-rated 1000 hp PD1T (T for tropical) engine; 44 examples were built between 1964 and 1966 in Bryansk, of which four remained in the USSR. Later variants for Cuba were identified by the suffix ‘K’, but unfortunately I have no information on their production. Export to European countries included standard Soviet versions suited for the 1435 mm track, i.e. TEM2A and TEM2AM.
Mention has also to be made of further development of the basic design, which indeed proved extremely prolific. Thus, TEM3 (1979 – 1992, 29 examples) featured different trucks, while TEM5 (1969 – 1974, 17 examples) was an even more extensive redesign, with the 6D49 diesel engine – some of its features were used in the TEM2M, which in fact had been initially designed TEM5M. TEM15 (1987 – 1995, 194 examples), developed from TEM2M, was intended for Cuba, but most went to Soviet and later Russian industrial establishments. Further development led to TEM16, TEM17 and TEM18: the latter, with the 1-PD4A diesel engine, finally went into series production in 1992 and eventually replaced its older kinsmen, over 1700 being built until mid-2017. At the time of writing (January 2018) TEM18 still remains in production; a single example saw some service in Poland with LHS (broad-gauge line, a PKP subsidiary).
TEM2s were widely used in the USSR and Russia and still remain in service, as the most numerous heavy diesel switchers in the former Soviet republics. On January 1, 1976, 1501 TEM2s and 215 TEM2As were used by Soviet railways, plus probably many more by various industrial operators. According to KMD, in 1992 there were 3418 examples of all versions in use in former USSR countries. Marco van Uden (www.railfaneurope.net) gives over 3300 locomotives of this type used in former Soviet Republics (Georgia, Kazakhstan, Latvia, Lithuania, Moldova, Russia and Ukraine), but it is not clear if this number includes those used by industrial operators – most probably not. As figures concerning export are very hard to find, it is virtually impossible to estimate the total output: ‘about 10,000’ sounds reasonable.
First examples of this locomotive in Poland were purchased in 1974 for sand railways: TEM2-001 (6740/1974) entered service on April 1. Supplies to PKP started two years later. In accordance with the system used by PKP, they were designated SM48, but this applied only to those used by the state railways: industrial operators retained the TEM2 code, although it seems that most – if not all – corresponded to the TEM2A variant and ran on the 1435 mm track only. Most locomotives of this type purchased by PKP were intended for heavy freight handling stations along Poland’s eastern border (during the Communist era affectionately referred to as ‘dry ports’), where replacement of elderly Ty23 and Ty2 steam locomotives was urgently needed. In all, PKP acquired 130 machines, all built by Bryansk factory, in two batches. The first one (SM48-001 through SM48-086) was supplied between 1976 and 1978. The second one (SM48-088 through SM48-130) corresponded to the TEM2U variant and was supplied between 1987 and 1989. Of these, 25 served on the LHS broad-gauge line (now a PKP subsidiary), but all had been transferred there from various regional managements. Two of them (SM48-028 and SM48-034) have been scrapped and some others converted to standard gauge – trucks could be easily replaced and some machines underwent such conversions more than once.
Much more TEM2s were supplied to various industrial operators, retaining their original factory designation plus service number. Of these, first 207 examples corresponded to the older TEM2A variant; last of them, TEM2-207, was sold to PKP in 1982 and became SM48-087. Those from TEM2-208 onwards corresponded to the later variant with modified, more angular body. Last of them, TEM2-310, was supplied to Staszic colliery in 1990. This makes a total of 309 machines of this type purchased to industrial operators. Several locomotives earmarked for PKP were eventually supplied directly to industry with changed designations and some numbers did duplicate, which has caused some confusion among railway fans, especially those addicted to statistics. Irrespective of the owner, common nickname of this locomotive is ‘Tamara’, obviously after the original designation.
Despite many diesel locomotives being written off in Poland during the 90s, TEM2 / SM48 class is still in service in quite large number, only few having been withdrawn. According to the rosters given in AL, 118 machines were still in use at the beginning of 2002 with PKP only. Given their comparatively young age, robustness and quite high reliability, they will probably remain in use for a long time. They are well suited for operation in low temperature, even -50°C – no wonder, with their Russian ancestry; however, wide use of asbestos for thermal insulation is certainly a reason for embarrassment and unacceptable by current environmental standards. High fuel and oil consumption is also a problem, but replacement of obsolescent low-speed diesel engines (rated power at 750 rpm) is now considered too costly and thus unjustified. So far, only four of twelve examples operated by Pol-Miedź Trans company (service numbers 033, 035, 181 and 298) were rebuilt. Two were fitted with MTU 12V396TC14 engines rated at 1015 kW with new state-of-the-art control systems; they were delivered in 2003. Two other examples followed in 2004, fitted with MTU 12V 4000 R41 diesels, rated at 1500 kW. These two conversion are known under semi-official designations SM48M and TEM2/15M, respectively. Until now (early 2010) no more conversions have been reported.
In October 2008 a private trading company purchased a second-hand TEM2 (s/n 5455/1977), which had completed a routine overhaul at a repair shop in Poltava, Ukraine. This locomotive was then offered for sale (for 1,350,000 Polish zloty – about 485,000 US dollars at that time); later, still with original service number TEM2-5455 and Ukrainian livery, it was leased to Hagans Logistics and used for switching in Zduńska Wola Karsznice. In early 2011 this locomotive was transferred to Wrocław-based Majkoltrans company. It is not clear if further purchases are planned.
An extensive modernization of this type was proposed by Newag in 2010. This locomotive, with factory designation 15D or 16D (for standard and broad gauge, respectively), is fitted with Caterpillar CAT 3512C diesel engine, AC/DC transmission and completely redesigned body. First example began service tests in mid-2010. 15D/16D is in fact a new design and shall be described under a separate entry.
