This model was made by Märklin from 1964 to 1976. Two different editions were made.
The NSB Di3b, the prototype for Märklin 3068:
Axel order A1A' A1A, or 0-6-6-0'. A1A' A1A means that the
locomotive had two bogies with three axels each. The front and rear axel
of each bogie had it's own electric motor, therefore not mechanically
connected. In other words, the centre axel of each bogie had no traction
motor. NSB Di3b 641 to 643 was initially meant for the Finish railway
company VR, but due to political reasons VR bought some other locomotives.
The Märklin model:
Both versions:
The chassis is made of a metal plate, to which all components are
installed. The rear bogie is driven by a large flat collector AC motor
(LFCM for short). The pick-up shoe is installed under the front
bogie. Normal windows are installed in the metal body, so are several ladders and handrails.
Length 20,5 cm.
