Polish origin of these locos can be traced from headlights, which had been obviously intended to comply with Polish standards and were later modified.
Nostalgic picture of the SP32-073 between Załuż and Lesko, taken by Ryszard Rusak on October 10, 2009 (thanks a lot for permission!). Nostalgia is fully justified – this was the last service of a SP32 in the Bieszczady mountains, where they had been in use for a long time.
Surprise! A modernized, but recognizable LDE130 sold to South Africa and photographed near Johannesburg in autumn 2010 (photo by Jean Dulez via Chris West – many thanks!). Possibly this is an unrealized SP32: any information is most welcome.

Steam locomotives remained in service with local passenger trains in Poland until 1990s, longer than in any other European country. A need for some replacement was, however, recognized much earlier. Indigenous classes SP45 (later SU45) and SU46 were successful machines, but their production was halted in 1977 and, despite some efforts, could not be re-commenced in the 1980s, due to economical crisis; moreover, these locomotives were too heavy and powerful for many potential services. It was therefore decided to order a new diesel locomotive from the 23 August works of Bucharest (former Malaxa, then FAUR). Romanian manufacturers had already supplied successful standard-gauge and narrow-gauge diesels for PKP (ST43 and Lxd2, respectively), so their capabilities seemed unquestioned. A contract was thus placed for 200 examples.
Contrary to the above-mentioned earlier classes, new locomotive, with factory designation LDE130, was of a completely new design, developed specially for PKP, and had some novel and modern features, like ac generator, electrodynamic braking and adjustable control desk. Certain elements and sub-assemblies were, however, adapted from earlier locomotives (e.g. traction engines, wheelsets and suspension were the same as in type 060DA, or PKP class ST43). Initially it was intended to fit multiple control, hence new machine was designated SP49. First two examples, SP49-001 and SP49-002 (serial numbers 24995 and 24996) were delivered in 1985, but soon it was decided to proceed with the single-control variant only, so class designation was changed to SP32 and in 1987 both prototypes were re-classed, to be written off in 1992. Two SP49s saw little service, so few photos are known, but some – of unknown authorship – can be found at various Internet sites.
Initial service experience with SP32 was far from satisfactory. New locomotives quickly proved very unreliable and manufacturing quality turned out to be poor. Engine, generator and compressor failures were commonplace. Despite many detailed improvements, introduced in later batches, this situation never substantially improved and SP32 immediately earned itself a contemptuous nickname of ‘Ceausescu’s revenge’. At times one-third of the entire fleet was immobilized due to serious failures and it was not uncommon for a SP32 to be accompanied by a ST43, ‘just in case’. Moreover, these locomotives proved too weak for many tasks, especially in mountainous areas and during winter, when car heating was on (and demanded some 250 kW with a six-coach draft). No wonder, thus, that only 152 examples were delivered and orders for the remaining 48 were cancelled. Last two locomotives arrived in 1991 (serials 25570 and 25571), but went directly to railway stock repair works in Piła (now Interlok) and later were given service numbers SP32-001 and SP32-002, replacing two prototypes withdrawn earlier that year. For a comparatively ‘young’ class, withdrawals started early. On January 1, 1999, PKP had (according to rosters quoted in SK) only 102 examples, not all of them serviceable. It was intended to retain 100 machines in service and have them re-engined until 2005, but due to financial problems only a handful finally underwent such conversions. Five examples (SP32-073, -096, -147, -148 and -149) were fitted with new MTU 12V396TC12 diesels (license-built in Romania) of the same rating as the original ones. Between 2000 and 2003, further ten – of initially planned 96 – underwent more thorough modernizations; apart from numerous minor improvements, they were fitted with MTU 12V396TC14 diesels rated at 1380 hp and state-of-the-art control and diagnostic systems. All locomotives from the second batch were renumbered. First of them, SP32-130, became SP32-201 and returned to service in November 2000. Nine more followed: SP32-046 (renumbered to SP32-202), -044 (203), -053 (204), -113 (205), -043 (206), -062 (207), -076 (208), -110 (209) and -128 (210). Formally they are owned by a leasing company, but have retained original PKP livery. All remaining 87 SP32s have been withdrawn from active service between June and July 2004, even if some of them have not been formally written off. Further modernizations seem rather unlikely. Between 2009 and 2010, Technical University of Kraków submitted a project of extensive modernization, including re-engining (Caterpillar CAT 3512 diesel), thoroughly re-designed cab and new electric, cooling and exhaust systems; this never saw fruition. Many withdrawn SP32s were stored at the railway stock repair works (ZNTK) of Poznań, awaiting a decision on their future. One of them (SP32-120, 23 August 25427/1989) has been overhauled and adapted for switching at the company premises in 2004, but four years later it was transferred to STK company of Wrocław and later withdrawn. Initially SP32s operated mainly on non-electrified secondary and local lines in south-eastern Poland and Lower Silesia. In early 2010s all operational SP32s were concentrated in Krzyż and Chojnice; this modest fleet was used mainly on non-electrified lines in western Poland. According to an article by Wojciech Kamiński (SS vol. 3/2016), last operational SP32-206 was withdrawn from use in November 2015. Currently (September 2016) only two SP32s of the ‘older’ modified variant with 12V396TC12 diesel engines still remain in the PKP Cargo rosters, namely SP32-148 and SP32-149. There is a project to preserve the former, which has gained some support, but no decision has yet been made.
Although LDH130 never served with Romanian state railways CFR, a number of these locomotives (most probably from those ordered by PKP and not accepted) went to several industrial operators. According to Tamas Haller (thanks a lot!), they numbered about 30 to 35, but only three or four are currently in regular use. These engines have retained their factory type designation, with consecutive service numbers.
SP32 was the last class, ordered in quantity for PKP, until the appearance of EU43 in 2008. Most of these locomotives were outlived in service by their elder predecessors and only a handful remained in use for more than twenty years.
