Production numbers and years were 7268/1909 and 7858/1910.[1] The fortress was in Finnish hands when Finland became independent. The fortress was not needed after the Treaty of Tartu in 1920.[1] It was therefore decided to cancel the order for the locomotives. But this was not possible so it was decided to use the locomotives in the dismantling of the fortress. In 1919, the second locomotive, 7858/1910, was sold to as an industrial locomotive.[1] The first locomotive continued to work dismantling the fort until 1922 when it was acquired by a building company in Hanko. After this the locomotive was sold to Enqvist Ltd Ab, Tampere who scrapped it in 1951.[1] The second locomotive was purchased by the VR Kuopio depot and given the running number 68. The locomotive was still running in the 1960s. The locomotive was used until 1962 and finally withdrawn in 1967.[1] In the early 1980s it was restored externally and placed in the Kuopio locomotive shed. It was discovered in 1986 by Savo Steam Transport Museum. Unfortunately, the museum project floundered and the locomotive was plinthed outside a restaurant.[1] In 2008 it was decided to restore the locomotive. On 24 March 2009, the locomotive was moved to Hyvinkää workshop, where ultrasound measurements were taken.[1] The final restoration was carried out by ABB Services and the Jokioinen Museum Railway, where the locomotive arrived on 8 May 2009. The locomotive was presented to the public on 17 June 2010.[2] References1. ^1 2 3 4 5 6 7 {{cite web|url=http://yle.fi/alueet/hame/2010/06/leena_on_pieni_hidas_ja_tehoton_1776781.html |title=Leena on pieni, hidas ja tehoton | Häme |publisher=yle.fi |date= |accessdate=2012-01-30}} {{refbegin}}2. ^{{cite web |url=http://www.rautatie.org/web/en/default.asp |title=Finnish Railway Museum - Welcome! |publisher=Rautatie.org |date= |accessdate=2012-01-30 |archive-url=https://web.archive.org/web/20130516182252/http://www.rautatie.org/web/en/default.asp |archive-date=2013-05-16 |dead-url=yes |df= }}
