Numbering
The first letter combination of the type defines the category of stock.
El: Electric locomotive
Di: Diesel locomotive
Skd: Shunter tractor
BM: Multiple unit
The numbers following the letters are the series. For the El and Di locos, they are numbered chronologically from when they were ordered by NSB. For multiple units, electric units are numbered starting with 62 and diesel starting at 83. Following the series number is the road number, unique for each stock. This number has three or four digits.
Livery
Traditionally NSBs electric and diesel locomotives and carriages were painted green, but in the 1970s this was replaced with red. Shunters were given a yellow color with red cabs. During the late 1990s and 2000s a new color scheme was introduced with multiple colors. Express trains were painted blue and silver, regional trains red and silver while local trains became green and silver. The freight trains were moved to the subsidiary CargoNet and painted grey, the Airport Express Train was painted silver and while the tourist railway Flåmsbana got green trains.
Transferred to Malmtrafikk, and sold to Sweden's Hector Rail in 2004 where they served until 2019. In 2020 they were sold to Grenland Rail, Norway where 4 locomotives remain in service.
