VR Vv13 and VR Vv14 are the series designations of the Finnish state railway VR-Yhtymä for a series of small locomotives that were delivered from Valmet to the state railway in 1953-1960 . A total of 41 locomotives were produced. The manufacturer's internal model names were Move51h (hydraulic) and Move51m (mechanical).
The type designation Tve3 was introduced in 1960.
history
Vv13
In 1952, the State Railways ordered two locomotives with hydraulic transmissions suitable for medium-heavy shunting work from Valmet. The basis was the tried and tested Move51h that Valmet had already supplied to industrial companies. The locomotives turned out to be very suitable, so further batches were ordered. The last copies were completed in 1960.
Vv14
In order to compare the hydraulic and mechanical transmission, the state railway ordered five locomotives with the mechanical transmission type Move51m in 1953 . However, the hydraulic transmission turned out to be cheaper to use. Therefore no further Move51m machines were ordered. The locomotives with mechanical gears were given the type designation Vv14. The production with mechanical gear was stopped again in 1954.
Tve3
In 1960, both the Vv13 and Vv14 locomotives were given the common series designation Tve3, with the serial numbers changing.
The locomotives were used at various locations in the Finnish rail network for medium-heavy shunting work, with the Vv14 (Move51m) series mainly in service in Hamina . They replaced the steam locomotives of the Vk , Sk , Tk1 and Tk2 series that were previously in the shunting service . Due to the low top speed, they were only used in handover traffic on short routes.
technology
The locomotives had a welded body made of steel plates. To add weight, additional weights were placed in the end girders. The engine front was in front of the end cab. Older locomotives differ in appearance from newer ones, as from number 468 the structure of the driver's cab and the engine room cover have been changed. Older locomotives had a sloping front of the engine room cover, while the newer locomotives had it vertical. The last locomotive with a sloping engine room cover was Vv13 1766 (Tve3 467, 536/1957).
Some of the locomotives were originally painted green, but were later given the normal red and yellow color scheme of the state railway.
The locomotives had a 350 HP two-stroke GM two-cylinder diesel engine, those of the Move51h series were equipped with hydraulic and those of the Move51m series with mechanical transmission. The power was transmitted from the gearbox to a jackshaft at the end of the locomotive, from where it was transmitted to the axles via coupling rods . The maximum speed of the locomotives was 30 to 35 km / h. They had a Westinghouse - air brakes and a mechanical hand brake .
Whereabouts
All state railroad locomotives were retired in the 1990s. Some locomotives have been preserved in industrial companies and as museum locomotives.
The following locomotives have data from their résumés:
- Tve3 464 and 479 (formerly Vv13 1763 and 1778, Valmet Oy 533/1957 and 551/1960) are located in the museum works of Höyryraide Oy in Nurmes , which opened on August 17, 2013 , to which Hv3 995 from Iisalmi has also moved. They were brought there from Suolahti in September 2013 .
- Tve 478 (formerly Vv13 1777) was sold to an industrial company and was parked in Voikkaa in summer 2018 .
