HKR 5 steam locomotive overhaul
This blog follows overhaul of the steam locomotive number 5 "Sohvi" of the ex Hyvinkää - Karkkila railway (Tampella 289/1917) on the Jokioinen Museum Railway.
Background and history of the locomotive
In 1917, the then Hyvinkää-Pyhäjärvi railway ordered the third and last new tank locomotive from Tampella. The sister locomotives of number 5, locomotives number 3 and 4, had already been delivered to the railway in 1911.
The locomotive was completed on 31.12. 1917, being the first locomotive to be completed in independent Finland. The locomotive was used to haul mixed and freight trains from 1918 until the closure of the track in 1968.
After the Hyvinkää-Karkkila railway was closed the locomotive was doanted in 1969 to the associtaion "Friends of Locomotives" and moved to Forssa. After a couple of years of renovation work, the locomotive started museum train traffic in Finland in August 1971. This year marks exactly 50 years of that event and the intention is that the refurbished locomotive will pull a train to celebrate 50 years of Finnish museum train traffic in the early summer of 2021.
The aim of the locomotive repair work is to repair the locomotive's leaking water tanks, restore the locomotive's firewood bunker to its original appearance, paint the locomotive in its original color and service and repair the locomotive's steam engine.

Done at the end of last week and in the weekend:
The wheels have been cleaned, the truck wheels completely cleaned. All of the wheels are primed and top painted. The water glasses have been repaired, the valves have been grinded and packed. The throttle handle has been rebuilt. The back of the firewood bunker was built and the steam dome cover was finished.
Things to do: Fixing the painting of the frame, second layer of painting would make a difference on both the frame and especially the wheels. Grinding of the Turret Valve of the fountain would now be easy to do. The window frames (loose) still need to be sanded and painted black.
The overhaul of Sohvi has now progressed so far that the locomotive's boiler jacket has now been painted three times with top coat paint and the railings of the firewood bunker have been started to be restored to their original appearance.
In the days between Christmas and New Year a lot of work has been done at Minkiö with the 103-year-old locomotive. The modification work on the fire wood bunker was continued with laser precision. The boiler jacket was cleaned, primed and painted 2-3 times. The frame and wheels were scraped, sanded and cleaned. The frame was painted with primer and topcoat. Once we get the blue topcoat paint the wheels can be also painted.
Before painting, it was time to wash the locomotive frame and boiler lagging of all the dirt that had accumulated in them. The locomotive was washed with a hot water pressure washer, after which scraping of the old paint from the frame, boiler blades and wheels will begin.
Renovation work on the steam locomotive Sohvi will continue this week as well. The locomotive's water tanks are waiting to be repaired and the locomotive's cab will be converted to its original appearance. The frame, wheels and machinery are serviced and painted. The locomotive is to be restored as close as possible to its 1917 appearance.
The next big step was to remove the locomotive cab. Now the work is over and the cabin is detached and lifted by a shop crane next to the locomotive. Most of the dismantling work has now been done and the actual repair of the locomotive can begin.
