OKa1
OKa1 was the designation used by the Polish State Railways, PKP for light steam locomotive of the former Latvian State Railways Tk series. Built in 1928–1934, the units were of German and Latvian production. After 1945, it was used by the Polish State Railways; it was the only steam locomotive in Poland with one driving axle. History In 1928, management of the Latvian State Railways placed an order for the construction of light and economical locomotives to support suburban traffic. A total of 20 were purchased, of which the first three were built in Weimar Republic, Germany (Nos. 231–233) at the Hohenzollern plant in Düsseldorf. Locomotive trials were successful, so in 1931 a further six were ordered from German plants (234-236 - Krupp and 237-239 - Henschel), with final assembly and the construction of various parts (such as the driver's cab and water tanks) carried out by the Latvian Fēnikss plant in Riga. Slight improvements to the design were made over the first batch o ...

OKf100
OKf100 was the designation used for a single First Czechoslovak Republic, Czechoslovakian-built passenger steam locomotive, formerly part of the Lithuania, Lithuanian TK series, used by the Polish State Railways. After 1945, one member of this series ended up in Poland, classified as the only example in the OKf100 series. The locomotive belonged to the Lithuanian TK series of passenger tank locomotives, consisting of four units, manufactured in 1932 by Škoda Works of Czechoslovakia and bearing numbers 11 to 14. These locomotives originally ran on Standard-gauge railway, standard gauge tracks, but after Lithuania was Soviet occupation of the Baltic states (1940), annexed by the Soviet Union, USSR in 1940, they were converted into Broad-gauge railway, broad-gauge units. During World War II, they found themselves in Austria, again converted into standard gauge. Unit 14 (factory number 754) was delivered to Poland, being temporally numbered as PK 14 for unknown reasons. During World ...

Warsaw Railway Museum
The Stacja Muzeum is located at the former Warsaw Główna PKP railway terminus and is very close to the Warszawa Ochota railway station. The museum's exhibits are divided into permanent and temporary collections — the latter being displayed inside the museum's galleries. The permanent collection consists of historic rolling stock that is displayed on the tracks outside, including one of the few remaining armoured railway trains in Europe. The museum also contains a library which houses many books on the subject of Polish railways. During the interwar period the museum's headquarters were located at Nowy Zjazd Street. The museum was reestablished at the present site, as Railway Museum in Warsaw (), in 1972. On 30 July 2009, PKP S.A. the Polish state railway company served notice to quit on the Museum authorities requiring them to vacate their current location by 31 August 2009. However, as of May 2015, the museum remained in place and open to the public. The museum was di ...

Dyneburg
Daugavpils (; russian: Двинск; ltg, Daugpiļs ; german: Dünaburg, ; pl, Dyneburg; see other names) is a state city in south-eastern Latvia, located on the banks of the Daugava River, from which the city gets its name. The parts of the city north of the river belong to the historical Latvian region of Latgale, and those to the south lie in Selonia. It is the second-largest city in the country after the capital Riga, which is located some to its north-west. Daugavpils is located relatively close to Belarus and Lithuania (distances of and respectively), and some from the Latvian border with Russia. Daugavpils is a major railway junction and industrial centre and was an historically important garrison city lying approximately midway between Riga and Minsk, and between Warsaw and Saint Petersburg. Daugavpils, then Dyneburg, was the capital of Polish Livonia while in Polish–Lithuanian Commonwealth. Following the first partition of Poland in 1772, the city became par ...

Rolling Stock Of Latvia
Rolling is a Motion (physics)#Types of motion, type of motion that combines rotation (commonly, of an Axial symmetry, axially symmetric object) and Translation (geometry), translation of that object with respect to a surface (either one or the other moves), such that, if ideal conditions exist, the two are in contact with each other without sliding (motion), sliding. Rolling where there is no sliding is referred to as ''pure rolling''. By definition, there is no sliding when there is a frame of reference in which all points of contact on the rolling object have the same velocity as their counterparts on the surface on which the object rolls; in particular, for a frame of reference in which the rolling plane is at rest (see animation), the instantaneous velocity of all the points of contact (e.g., a generating line segment of a cylinder) of the rolling object is zero. In practice, due to small deformations near the contact area, some sliding and energy dissipation occurs. Neverthe ...
