Hr1 class (original classification P1) was the largest passenger express steam locomotive built in Finland. Twenty-two were built between the years 1937–1957. They were numbered 1000–1021.

Contents

In the thirties there was a need for faster and heavier express trains in Finland, and the Hv1–Hv3 classes were not powerful enough to fill the need. Lokomo Oy in Tampere built first two prototypes, and after successful trials 20 more were built. Most of the locomotives were fitted with Wagner-type smoke deflectors, but the last two, which were equipped with roller bearings, had Witte-type deflectors.

The nickname of the locomotive was "Ukko-Pekka" meaning approximately "(respected) Grandpa Pekka", after the President of Finland Pehr Evind Svinhufvud.

The Hr1 was built for coal firing, but during the coal shortage after the war in 1945, birch wood was used as fuel. Larger chimneys needed for extinguishing wood sparks were temporarily fitted.

The Hr1s were the most important express steam locomotive and could justifiably be called the "flagships" of VR until 1963, when diesel locomotives started to replace steam. Their use ended officially in 1971, but two roller bearing Hr1s were returned for a short use in spring 1974. One engine, 1005, was a participant on the worst peacetime railroad accident in Finland, kuurila accident, in 1957. The engine is preserved at Haapamäki.

Hr1's sister locomotive was the Tr1 class, otherwise similar, but with 2-8-2 wheel arrangement and smaller diameter drivers for cargo train use.

VR Group State-owned railway company in Finland

VR Group, commonly known as VR, is a government-owned railway company in Finland. VR's most important function is the operation of Finland's passenger rail services with 250 long-distance and 800 commuter rail services every day. With 7,500 employees and net sales of €1.251 million in 2017, VR is one of the most significant operators in the Finnish public transport market area.

4-6-0 Wheel arrangement of a locomotive with 4 leading wheels, 6 driving wheels and no trailing wheels

Under the Whyte notation for the classification of steam locomotives by wheel arrangement, 4-6-0 represents the configuration of four leading wheels on two axles in a leading bogie and six powered and coupled driving wheels on three axles with the absence of trailing wheels. In the mid 19th century, this wheel arrangement became the second most popular configuration for new steam locomotives in the United States, where this type is commonly referred to as a ten-wheeler. As a locomotive pulling trains of lightweight all-wood passenger cars in the 1890–1920s, it was exceptionally stable at near 100 mph (160 km/h) speeds on the New York Central's New York to Chicago Water Level Route and on the Reading Railroad's Camden to Atlantic City, NJ, line. As passenger equipment grew heavier with all steel construction, heavier locomotives replaced the ten-wheeler.

Helsinki commuter rail

Helsinki commuter rail is the commuter rail system serving Greater Helsinki, Finland. The network is part of the HSL network, and is operated by VR, the Finnish state-owned national railway company. Together with the Helsinki Metro, buses, and trams, the network forms the heart of Helsinki's public transportation infrastructure.

Helsinki Central Station (HEC) is the main station for commuter rail and long-distance trains departing from Helsinki, Finland. The station is used by approximately 400,000 people per day, of which about 200,000 are passengers. It serves as the terminus for all trains in the Helsinki commuter rail network, as well as for all Helsinki-bound long-distance trains in Finland.

Vyborg railway station

Vyborg is a railway station, located in the town of Vyborg in Leningrad Oblast, Russia.

The history of rail transport in Finland began on January 31, 1862, with the opening of the railway line between Helsinki and Hämeenlinna. By 1900 most of the future main lines had been constructed, including the line to St. Petersburg. By the time of the birth of the new Finnish Republic in 1917 lines connected all major cities, major ports, and reached as far as the Swedish border, and inner Finland as far north as Kontiomäki in Paltamo region, as well as eastwards into Karelia.

VR Class Hr11

The VR Class Hr11 was the first class of line-haul diesel locomotives used by Valtionrautatiet. Only five units were built, all delivered by Valmet in 1955. The Maybach diesel engines used in the locomotives proved highly unreliable, resulting in a complete overhaul of the engine-transmission system in 1956–58, but this did not solve all of the reliability problems. The Hr11 series was withdrawn from service in 1972.

VR Class Tk3

The Finnish VR Class Tk3 was a 2-8-0 light freight locomotive. It was the most numerous steam locomotive class in Finland with 161 built. 100 locomotives were constructed between 1927 and 1930, with a further 61 ordered and constructed 1943–53. They were numbered 800–899, 1100–1118, and 1129–1170.

The Dr14 is a heavy shunting locomotive used by VR Group. Some of the locomotives can be radio controlled.

VR Class Pr1

VR Class Pr1 was a tank steam locomotive for local passenger services of Finnish railways.

VR Class Hv1

The Finnish Hv1 class was a 4-6-0 express passenger train locomotive. 42 were built between 1915 and 1921. They were numbered 545–578 and 648–655.

VR Class Vr1

Before 1942 VR Class Vr1s originally had the class name was L1. The Vr1 was a powerful and effective locomotive. Part of them were built by Tampella and part by Hannoversche Maschinenbau AG of Germany. They were numbered 530–544, 656–670, 787–799 and were nicknamed “Kana” ("Hen"). They were operation from 1913-1974.

VR Class Tr1

The VR Class Tr1 is a class of heavy freight locomotive built in Finland and Germany. Before 1942 VR Class Tr1s originally had the class name R1. They were nicknamed “Risto”, after the Finnish President Risto Ryti. They were numbered 1030–1096.

VR Class Pr2

The Finnish VR Class Pr2, nicknamed "Henschel", was a passenger tank class ordered from the Henschel & Son locomotive workshops by the Estonia State Railways in the spring 1939 and completed in 1941. The outbreak of the Second World War prevented their delivery to Estonia, but at least a few of these engines did manage to operate in Latvia in 1942. These engines became superfluous, because the Germans were converting the Baltic tracks to standard gauge, and so Finland could purchase these four engines. They were classified Pr2 and numbered 1800–1803 after their arrival in December 1942. The Pr2 tank engines were quite advanced locomotives, based on the Henschel Class 62 tank engine design of 1928. After their initial problems were solved, they proved to be fast runners and an ideal addition to the motive power roster. They were originally built by as oil-burners, and reverted to this type of fuel between 1947 and 1954 when oil prices were low. The Pr2 was very fast with its 1,830 mm wheel diameter. One of the Pr2 engines achieved 144 km/h during a test trial run. No. 1803, the final Pr2 in service, was withdrawn in May 1960. Only No. 1800 has been preserved at Haapamäki.

VR Class Dr12

VR Class Dr12 was a heavy diesel locomotive of Valtionrautatiet. The first 6 locomotives were ordered in 1956. They entered service between 1959 and 1963. The locomotives were built by 2 manufacturers, Valmet and Lokomo, both based in Tampere. All Hr12 class locomotives with even numbers were produced by Valmet, while all odd numbers were produced by Lokomo. The locomotives were withdrawn in the early 1990s.

VR Class Dr13

VR Class Dr13 was a heavy diesel locomotive used by VR Group. The Dr13 was designed by the French company Alstom. The class consisted of 54 locomotives, of which the first two were built by Alstom’s factory in Belfort, France and were shipped to Finland in 1962, while the rest were built in Tampere at the factories of Lokomo and Valmet. The first Dr13 series locomotive came to Finland on 24 October 1962. The Dr13 series was introduced between 1962–1963, and the last units were withdrawn by June 2000.
