NSB Class 18

The Norwegian State Railways 18 (18a, 18b & 18c) Class are 4-6-0 tender steam locomotives.
==History==
The 18 (18a, 18b and 18c) class are a class of thirty-five tender 4-6-0 locomotives. The first members of the class were built from 1900 by Sächsische Maschinenfabrik (Formerly Richard Hartmann Locomotive Works) of Germany for the Norwegian State Railways as their 18a class. Later members were converted to 18b and c subclasses with many more 18c members being constructed new by the Hamar Iron Foundry of Norway. The class were used all over the network. The last of the class to be withdrawn was 18c No.255 in 1969.https://forsk.njk.no/mdb/mdb.php?hid=27&aut= (Translated by Google)https://jernbane.net/bo/subpage.php?s=3&t=110 (Translated by Google)http://members.ozemail.com.au/~telica/Norway_Gamle_Vossebanen.htmlhttp://www.nic.funet.fi/index/pics/railways/Norway/historic/index.htmlhttps://www.ebe-data.com/Hobby/Jernbanebilder/Norge/Lok/Damp.htm#Normalspor (Translated by Google)https://www.steamlocomotive.info/vlocomotive.cfm?Display=5883https://www.railpictures.net/showphotos.php?road_number=18%20C%20%20255https://njk.no/tourist-information/the-old-voss-steam-railway-museumhttps://digitaltmuseum.no/011013102088/leveransefoto-av-damplokomotiv-type-18a-nr-138-som-ble-vist-pa-verdensutstillingen
===18a===
The first subclass of the 18 class were built and ran for a time on the Grefsen-Røykenvik, Grefsen-Gjøvik and Reinsvoll-Skreia lines. From 1964 one of these locomotives No.134 was the oldest locomotive operated by the Norwegian State Railways until it's withdrawal and scrapping in 1968. Only two of the 18a class managed to not be converted to 18c them being No.135 and No.157. None of the class managed to be preserved.
===18b===
The 18b subclass were designed, built and operated on the Gjøvik and Bergen lines. The last full 18b class locomotives were withdrawn and scrapped in 1962. Two of the class were converted to the 18c class. None were preserved.
===18c===
The most successful and largest of the class over half the 18 class were built or converted to the 18c classifications. These locomotives were of a heavier build and used all over the Norwegian State Railways main network.
==Preservation==
Only one member of the class was preserved that being No.255 of the 18c classification which is currently operational on the Old Voss Line preserved railway. It is owned by the Bergen Technical Museum.
