The SM25 (factory designation 9D350) is a Polish series of diesel shunter used by PKP. [1]
Plans for a locomotive with Voith hydraulic transmission (the first of its kind in Poland) were drawn up between the years of 1959 and 1960, alongside the design for the SN80 DMU — though the latter did not make use of the Voith system. The new locomotives were intended to replace the obsolete SM30 series — however, the SM30 was still being built long after production of the SM25 had ceased.
Manufacture of the SM25 began in 1961 and came to an end in 1963. During these years only three units rolled off the Fablok production line in Chrzanów, due to the severe difficulty in importing the hydraulic transmission units from Voith.
The three that were built were sent to the depot in Kraków where they remained in service until the late-1970s when they were sold to industry. [1]
One example — SM25-002 (serial number 5427), built in 1962 — has been preserved as an exhibit at the Warsaw Railway Museum.
The SM25 is a C locomotive. This means that there are three powered axles under the unit. They are not articulated relative to other parts of the locomotive and are driven via hydraulic transmission. The locomotive is powered by a four-stroke diesel engine. The SM25 had several improvements over previous classes in the SM series. The most notable being the revised positioning of the cab — which had been soundproofed — and platforms, with the intent of providing optimal conditions for shunting. [2]
A diesel locomotive is a type of railway locomotive in which the power source is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. The most common are diesel-electric locomotives and diesel-hydraulic.
The British Rail Class 43 diesel-hydraulic locomotives were built by the North British Locomotive Company (NBL) from 1960 to 1962. They were numbered D833–D865.
SM30 is a Polish series of diesel shunting locomotives used by PKP and industry, built by Fablok, Chrzanów. They were also used for a local traffic.
The M62 is a Soviet-built diesel locomotive for heavy freight trains, exported to many Eastern Bloc countries as well as to Cuba, North Korea and Mongolia. Beside the single locomotive M62 also twin versions 2M62 and three-section versions 3M62 have been built. A total number of 7,164 single sections have been produced, which have been used to build 5,231 single-, twin- and three-section locomotives.
SM42 is the PKP class for a Polish shunter diesel locomotive for shunting and light freight traffic, built by Fablok in Chrzanów.
SM03 is the name of a Polish diesel locomotive class in the PKP railway operator designation. The letters SM describe a diesel shunting locomotive.
SM31 is a Polish series of diesel shunting locomotives used by PKP and industry.

DB Class V 200 was the first series production diesel-hydraulic express locomotive of the German Deutsche Bundesbahn and – as Am 4/4 – of the SBB-CFF-FFS in Switzerland.
Luxtorpeda – a popular name of the famous Polish railcar from the 1930s.
Fablok is a Polish manufacturer of locomotives, based in Chrzanów. Until 1947 the official name was First Factory of Locomotives in Poland Ltd., Fablok being a widely used syllabic abbreviation of Fabryka Lokomotyw, among others as the company's telegraphic address. It is now named "BUMAR - FABLOK S.A.". Fablok is located in the town of Chrzanów in Lesser Poland. As of 2009, Fablok no longer builds new locomotives.
The NMBS/SNCB Class 77 is a class of 4 axle B'B' road switcher diesel hydraulic locomotive designed for shunting and freight work manufactured at the beginning of the 2000s by Vossloh Schienentechnik/Vossloh Locomotives at the Maschinenbau Kiel plant in Kiel, Germany for the National Railway Company of Belgium (SNCB/NMBS).
SM02 is a Polish series of diesel shunting locomotives used by PKP. 12 of the locomotives were introduced into PKP after 1954. It is the first diesel locomotive of Polish production.
The SM15 is a Polish diesel shunter used by PKP and industry — where it carried the designation Ls750H. It is based on the Soviet ТГМ3 (TGM3) locomotive.
SP30 is a Polish series of diesel passenger locomotives used by PKP.
The Voith Maxima locomotives are a family of diesel-hydraulic locomotives built by Voith Turbo Lokomotivtechnik GmbH & Co. KG., a subsidiary of Voith.
The Krauss-Maffei ML 4000 is a road switcher diesel-hydraulic locomotive, built between 1961 and 1969 by German manufacturer Krauss-Maffei in Munich, Germany. It generated 3,540 horsepower (2,640 kW) from two Maybach V16 engines. 37 examples were built for two North American railroads and one South American railroad.
The PKP class Lyd1 is a narrow gauge diesel locomotive class, covering two similar models built in Poland: WLs150 built by Fablok, and its development WLs180 (803D) manufactured by Zastal. It was used by Polish State Railways (PKP) on the narrow gauge railways in Poland, and on industrial railways.
CFR Series 040 DH are locomotives produced in large numbers, equipped with a hydrodynamic power transmission. They were used for shunting and light mainline service by the Romanian state railways CFR. In addition, 475 locomotives of this type were delivered to Romanian industrial companies, 263 units were delivered to Bulgaria, 42 units were delivered to industrial companies in Czechoslovakia, three units went to Iraq, two units went to China and one unit was delivered to the USSR.
Düwag Wadloper is a family of diesel railcars and diesel multiple units produced by the German Düwag plant in Düsseldorf. Between 1981 and 1983, a total of 50 vehicles of this kind were built specifically for the Dutch Nederlandse Spoorwegen railroad. At the beginning of the 21st century, they were mainly operated by private carriers; in 2006 they began to be phased out, and in 2008 they were sold to other countries. The trains went to carriers from Poland, Argentina and Romania. They were operated by Przewozy Regionalne, Masovian Railways and Koleje Śląskie, and also used by Trenes de Buenos Aires to operate a cross-border service between Argentina and Uruguay. They currently operate services connecting Argentina with Paraguay, and are operated in Poland by SKPL Cargo, as well as on several lines in Romania.
