PKP . [cite web|url=http://www.kolej.pl/jareks/wtpkp/sp32.htm|title=Chester Home Page|author=Jarek D. Stwarz|date=1997-2002|accessdate=2007-10-21]History
The start of the 1980s was the dawn of Polish
steam locomotive s era. New diesel locomotives were needed for pullingpassenger train s. [cite web|url=http://www.kmk.kkozle.pl/readarticle.php?article_id=15|title=Regionalny Portal Kolejowy|author=|date=2006-2007|accessdate=2007-10-21] Locomotives that were able to heat carriages with electrical systems were most in demand. [cite web|url=http://www.kolej.pl/jareks/wtpkp/sp32.htm|title=Chester Home Page|author=Jarek D. Stwarz|date=1997-2002|accessdate=2007-10-21] Due to an economic crisis within Poland, it was impossible to start local production, so PKP decided to buy 200 locomotives produced inFAUR works fromBukarest ,Romania . [cite web|url=http://www.kolej.pl/jareks/wtpkp/sp32.htm|title=Chester Home Page|author=Jarek D. Stwarz|date=1997-2002|accessdate=2007-10-21] This company had previously produced Lxd2 and MBxd2narrow gauge locomotives for PKP. [cite web|url=http://zalesie.eu.org/~gacka/serwis_kolejowy/|title=Serwis Kolejowy|author=Przemysław Gołembiecki, Tomasz Gacki|date=2003|accessdate=2007-10-21]First two locomotives began to work for PKP in 1985 and received the SP49 designation. Different series numbers were given as those locomotives were supposed to work in multiple steering. As other engines lacked that device, all locomotives were renamed to SP32-001 and 002. [cite web|url=http://www.bluefish.foxnet.pl/Tabor/Spalinowe/SP49/SP49.html|title=Lokomotywa pasażerska serii SP49|author=|date=|accessdate=2007-10-21] Units were appointed to the
Jasło ,Nysa ,Siedlce , andZamość depots. The very first month of service revealed a series of failures that were reported back to the producer. Changes introduced afterwards did not limit the breakdowns. The most serious problems included failures of the diesel engines,compressor s, andalternator s. Additionally, their power proved to be insufficient, especially during winter when heating the carriages. [cite web|url=http://www.kolej.pl/jareks/wtpkp/sp32.htm|title=Chester Home Page|author=Jarek D. Stwarz|date=1997-2002|accessdate=2007-10-21]These problems caused an end of their importation in 1991, after a total of 150 units. The last two locomotives (151 and 152) exchanged prototypes and their numbers were changed to 001 and 002. As the whole series had been far too young to be withdrawn, several attempts to upgrade the units were started. New diesel engines (12V396TC12 licensed by MTU) had the same power as previous ones, but were more reliable. They were installed in the following units: 073, 096, 147, 148, and 149.
In 2000, a more complex modernization of the SP32 series began. Locomotives were given new 12V396TC14 diesel engines with an electronic regulator produced by MTU, on-board diagnostics system, more convenient dashboards, fire extinguishing installation, and new lights. The leasing company that now owns and lends PKP modernized locomotives funded the modernization. Units with all those improvements were numbered from 201 to 210. Presently, only those locomotives are in use, with the rest remaining as reserve. About one-third of the locomotives have been scrapped.

Technical data
SP32 is a
Bo-Bo locomotive as it runs on twobogie s, each equipped with twoaxle s. Each axle is propelled separately by onetraction motor . Power fromdiesel engine to traction motors is delivered throughelectrical transmission . The electric heating system is powered by a 250 kWalternator that allows the locomotive to heat six carriages (assuming 40 kW power consumption per carriage). During summer months all power from heating is transferred to traction motors, thus increasing tractive effort. [cite web|url=http://www.kolej.pl/jareks/wtpkp/sp32.htm|title=Chester Home Page|author=Jarek D. Stwarz|date=1997-2002|accessdate=2007-10-23] Traction motors, bogies, transmissions, and compressor, as well as several different parts are similar to those used in ST43 locomotive.SP32 has a non-typical for Polish passenger locomotives box construction. It has only one crew compartment, located approximately two-thirds of way down the locomotive. Thanks to a replaceable dashboard, driving in both directions is comfortable. The relatively low weight this locomotive puts on rails allows it to run on tracks laid on unstable surfaces.
