This is a earlier car of the B3 generation and look different one that was seen earlier. Originally it was a part of the first major generation of all steel cars on NSB and this version was used as a tourist cars on the mountainous and very scenic mainlines. This is the reason with the large unusual window arrangements. The car seen here is how it looked in they last years, during its later years a middle window was blanked and many of these cars made it to the black and red scheme.
