Wacław Łopuszyński
Wacław Marian Łopuszyński ( Russian Вацлав Иванович Лопушинский , Wazlaw Ivanovich Lopuschinski; born July 15, jul. / 27. July 1856 greg. In Tykocin , † 16 February 1929 in Murowana Goślina ) was a Polish railway engineer and designer of steam locomotives , predominantly in Empire Russia was active.
Life
Łopuszyński was born in 1856 in what was then Russian-dominated Congress Poland . He studied in Saint Petersburg at the local institute for railway engineers, which he graduated in 1878. He then worked for various private Russian railway companies, for example in 1882 as an operations engineer in Fastow for the local railway company. He finally switched to the private Vladikavkaz Railway Company , founded in 1872 , which had opened the first section of its important main line in the foothills of the Caucasus from Rostov-on-Don to Vladikavkaz in 1875 . At this company he was appointed head of the mechanical engineering department in 1895 and was responsible for the design and procurement of new locomotives . In this role he designed some of the most important Russian steam locomotive series.
One of the widespread constructions of Łopuszyński was the Russian О series , first published in 1890 , which the Russian Ministry of Transport procured on a large scale after its proving on the Vladikavkaz Railway. Including the replicas after the October Revolution , over 9,000 units of this series were produced in several, slightly different series. His designs also included the Russian Ц series , which was manufactured from 1896, initially by Henschel & Sohn in Kassel and later by other plants , based on Łopuszyński's design . In addition to the Vladikavkaz Railway, they were also delivered to the Chinese Eastern Railway . The greatest success of his designs in terms of numbers was achieved by the Russian series Э , which was ultimately produced in over 11,000 units and is the most popular series in the world. It was designed by Łopuszyński in 1909 after the increasing freight traffic on the Vladikavkaz Railway could no longer be cope with satisfactorily with the previous locomotives. Łopuszyński's last draft for the Vladikavkaz Railway was the only Russian Pacific locomotive, first used in 1915 and designated as the Russian class Л after the first letter of his surname . A total of around 23,000 steam locomotives were built according to his designs, making Łopuszyński the numerically most successful locomotive builder.
After the victory of the Bolsheviks in the Russian Civil War , Łopuszyński returned to his native Poland in 1920. There he was still involved in the construction of the first Polish freight train locomotives, the Tr21 and Ty23 series, at Fablok in Chrzanów . He died in 1929 at the age of 72.
