SM42 (factory type 6D) is the most numerous locomotive type built in Poland. Designed by Fablok as a medium switcher and light freight locomotive, it remained in production between 1964 and 1992, with over 1800 examples built. SM42s were delivered both to PKP and to industrial operators. Many of them still remain in use, but obviously have become obsolete. This refers mainly to the prime mover: a8C22 diesel engine is, by current standards, heavy and uneconomical, and of course does not comply with latest emission regulations. Since mid-1990s several modernization packages have been proposed, all including installation of a new diesel engine.
In 1996 ZNTK Piła repair works (now PESA) rebuilt SM42-039 for PKP, with new MTU engine and AC main generator (plus several minor modifications). Re-numbered SM42-2000 (type 6Dc), this conversion, although successful, remained a single example. PTKiGK Rybnik sand railways, who had a considerable fleet of these engines, implemented a more advanced program, not only involving prime mover (this time 1065 hp MTU 8V396 TC14), AC main generator (LSG-850-90, supplied by Dolmel Drives, a division of ABB) and minor improvements, but also changing external appearance. New high-rpm diesel engine is much lighter (2.52 instead of 7.4 tonnes) and specific fuel consumption is lower by almost 9%. Modernized machine, designated type 6Dd (or Ls1000), has a modified body, with driver’s cab shifted forward and accessible directly from footplates. Cab equipment has been substantially upgraded, which has improved crew working conditions. Modernization of the first example (SM42-2536, s/n 10267/1979, which became Ls1000-001) at the company’s own workshops was completed in March 1999, second one (SM42-2197, s/n 8612/1973, Ls1000-002) followed three years later. No more conversions were ordered. In 2007 a major part of the PTKiGK Rybnik shares was purchased by PCC Rail, a division of German PCC SE holding. In 2010 the company was absorbed by DB Schenker Rail Polska. Ls1000-001 was sold to a private DLA operator in February 2013; in 2018 it was sold again, this time to a leasing company. Ls1000-002 is still operated by DB Cargo Polska, the successor of DB Schenker Rail Polska.
