Steam locomotives

TT-1770

<space=1em>German development

<space=1em>The TT series steam locomotives were designated as the 91 series during their operation on German railways, and even earlier, when there were no unified railways in Germany, they were designated as T9.3 on the Royal Prussian Railways.

<space=1em>The T9.3 series steam locomotives were developed by the German Union plant in Königsberg in 1901 and were intended for passenger and freight work, as well as for shunting. These were "universal" steam locomotives for secondary lines. They were very simple in design, operated on saturated steam and had a single-expansion machine. The design speed was 65 km/h.

<space=1em>In total, various German factories built about 2,050 steam locomotives from 1901 to the early 1920s, which was a significant number for Europe. Initially intended for the Royal Prussian Railways, these locomotives were also used on other "state" and some private railways.

<space=1em>Trophies

<space=1em>After World War I, due to military events, steam locomotives were scattered across many European countries, as they were actively used by the Germans in the territories they occupied. Several hundred T9.3 ended up in Poland, where they received the Tki3 series. These locomotives also ended up in Belgium and France. Russia received them on the first day of the First World War, when several Prussian T9.3 ended up at the Russian border station of Verzhbolovo (now Kybartai, Lithuania) at the wrong time.

<space=1em>In Germany in 1925 during the general renumbering of steam locomotives, T9.3 received series 91.

<space=1em>These steam locomotives first arrived in the USSR in 1939 Together with other locomotives of the railways of the eastern part of Poland, Tki3 ended up on the railways of the Soviet Union. A little later, together with the annexed Lithuanian Railways, several machines under the old Prussian designation T9.3 entered the USSR NKPS fleet. The bulk of the 91 series locomotives changed their citizenship to Soviet during and after the Second World War.

<space=1em>A large number of these locomotives were used by the Germans in the occupied Soviet territories, many of them remained as trophies after the Wehrmacht retreated to the west. On January 1 1946 the inventory park of the NKPS USSR included 77 steam locomotives of the 91 series, 21 former Polish Tki3 and three Lithuanian T9.3. These locomotives continued to arrive later, as reparations.

<space=1em>It is practically impossible to name the exact number of machines that ended up in the USSR. One can only speak approximately: about 200 steam locomotives entered the tracks of the Ministry of Railways, and about 70 more ended up directly on the tracks of industrial enterprises. Thus, we can talk about about 270 steam locomotives of the 91 series that entered the Soviet Union.

<space=1em>Operation

<space=1em>In industry, steam locomotives of the 91 series were used at various enterprises, located mainly in the European part of the country and in the Urals. The vast majority of them ceased their work in the 1960s.

<space=1em>On the railways of the Ministry of Railways, the 91series locomotives, which received the TT designation in 1952 (the Polish Tki3 retained the previous series), were used exclusively as shunting locomotives. At the same time, due to their relatively short length, they were well suited for work on turntables in fan depots. As an example, we can cite such depots as Babayevo, Riga, Alexandrov, Tambov, Malaya Vishera and others.

<space=1em>Apparently, it was TT 831, assigned to the Malaya Vishera depot, that became the last operational steam locomotive of the 91 series not only in the USSR, but also in Europe. It worked at shunting stations at the depot until 1979 Regular operation of steam locomotives of the 91 series on German railways ended in 1964, in Poland they finished their work in 1969 Currently, about 15 locomotives of the 91 series remain in Europe, of which only one or two are in working order.

<space=1em>Museum exhibit

<space=1em>The steam locomotive TT 1770 was built on September 10th 1913 at the Jung plant with the factory number 1935. Its first designation was KED Halle 7083. It indicated its place of operation — the Halle depot of the Royal Prussian Railways. Halle is located near Leipzig, but at that time it was part of the province of Saxony of the Kingdom of Prussia. The locomotive was listed in the same depot in 1945, so it is possible that it worked in the vicinity of Leipzig all these years, changing its designation in 1925 to 91 1770.

<space=1em>History is silent about how exactly the locomotive 91 1770 ended up in the USSR. Whether it was immediately exported to the Soviet Union or received later as part of reparations deliveries is unknown. According to German data, which should be treated with caution, it left Germany for the USSR in 1947.

<space=1em>It is also unknown when the locomotive ended up at the Kharkov Vtorchermet plant. According to the recollections of local old-timers, the locomotive worked as a factory locomotive and was abandoned together with the old depot, gradually being buried under piles of scrap metal.

<space=1em>A Long Journey to the Museum

<space=1em>In the spring of 1991 the locomotive was purchased from the factory by the Central Museum of the October Railway. After a rather complicated operation of loading onto a railway platform, carried out in two stages in the winter of 1991–1992, it arrived in St. Petersburg at the museum site in Shushary. At that time, no one imagined that the locomotive would end up in the museum exhibition 16 years later.

<space=1em>Over the years, the locomotive was unloaded from the platform and took its place among the numerous exhibits awaiting repair. The museum staff never left the thought of its repair, but there was no possibility of carrying out such a large-scale repair on their own, and there were no contractors willing to undertake such an atypical object for a reasonable sum. Meanwhile, the exhibition moved to Varshavsky Station, and the TT remained in Shushary.

<space=1em>Only in the winter of 2007 did it become possible to carry out restoration repairs on the locomotive at the branch of the experimental plant of the October Railway at Rzhev station. The locomotive was loaded onto a platform for the second time and sent to the plant at Rzhev-Baltiysky station. It should be noted that a similar volume of repairs to a museum locomotive has been carried out in our country once before — the restoration of the C 68 locomotive in the early 1980s.

<space=1em>February 29 2008 the repairs were completed. Once again, the locomotive was loaded onto a railway platform and sent to St. Petersburg by separate locomotives accompanied by museum specialists. At the museum at the former Varshavsky railway station, the locomotive was unloaded onto the railway tracks, and a little later a team from the experimental plant carried out its final assembly at the exhibition site.

<space=1em>June 29 2016, For the first time in many years, the steam locomotive traveled on its own axles from the closed museum at the former Varshavsky railway station to the new museum at the St. Petersburg-Baltiysky station. Contrary to expectations, the veteran survived the journey without causing any particular problems for the museum staff accompanying it.
