 A
diesel engine,
class Di.3, hauling a goods train. These locos, originally an
American type from General Motors, are still very common in Norway
as well as in several other European countries and are often called
Nohab, after the Swedish firm "Nydquist och Holm AB" who delivered
35 of these to NSB during the years 1954-1969. These multi purpose
diesel-electric locos exist in two versions, Di.3a and Di.3b, with
different wheel arrangements. The stamp shows one of the three
Di.3b, numbered 3.641-3.643. These have the axle arrangement
(A1A)'(A1A)' and a door at both ends. They were first built for the
Finnish state
railways, which later cancelled the order, and thereafter were
purchased by NSB in 1960. The original colour was olive-green with
white stripes. The engine develops 1775 hp and its working weight is
103 tons, length 18.9 m l.o.b., and it has a max. speed of 143 km/h.
The Di.3a was a Co'Co' with lower max. speed. This stamp is one of
eight stamps in a block
showing engines from different countries.
