The Norwegian government has given NSB approval to buy 26 new trains to operate services in Bergen and on the Gjøvikbanen line between Oslo and Gjøvik.
NSB has to date ordered 81 Flirt train sets from Swiss manufacture Stadler, of which 68 are in service.
The addition of more Flirts will give NSB the most uniform fleet in its history, says chief executive Geir Isaksen.
Isaksen said the government backing mean NSB can “continue to replace our oldest trains with new, modern and environmentally friendly trains” whilst improving capacity on the network.
The Norwegian government has committed to helping fund the new fleet in its 2016 budget. The budget also highlights that railway investment as a whole will be reduced in 2016, apart from maintenance and renewal which will receive additional investment.
