Soviet six-axle TEM2 heavy switchers were imported to Poland in considerable numbers: between 1974 and 1990 as many as 439 examples were obtained, both for PKP (class SM48) and industry. Based on ALCO type RSD1 from early 1940s, these locomotives could hardly be considered modern in the 2000s, mainly due to obsolete and uneconomical power plant. Between 2003 and 2004 six TEM2s were fitted with MTU diesel engines. In 2012 a much more extensive modernization package was proposed by Newag, with only frame and trucks retained from the basic design. Designated 15D (standard-gauge) and 16D (broad-gauge) and classed ST48 by PKP Cargo, this locomotive is intended for line service rather than switching. It is in fact a new design and is described under a separate entry.

In November 2014 IPS Tabor research and development institute, in co-operation with Pesa company, initiated a study on possible extensive modernization of type TEM2, with a modern, low-emission power plant conforming to current European standards, AC-DC transmission and thoroughly improved performance. Again, all that remained from old ‘Tamara’ were frame and trucks, the latter substantially modernized. Obsolete PD1M was replaced by MTU 12V4000R84 high-rpm diesel engine, rated power increasing more than twice. Another option is the R64 variant of this engine, de-rated to 2050 hp. Body has been completely re-designed, with lower engine cowling for improved forward view. Traffic safety devices and fire-extinguishing system, lacking in TEM2, have been installed. The locomotive (type 19D – rebuilt TEM2-154 from the Orlen KolTrans fleet, built in 1980) was completed in January 2017. Numbered 19D-001, it was transferred to Rail-Loko private leasing company and in May 2018 began service tests with Pol-Miedź Trans. Until now (February 2020) no information on possible further conversions has been released. According to some sources, type 19D was offered to PKP Cargo, which intend to modernize a number of their SM48s, but type 15D/16D from Newag was finally chosen.
