0n3 Z4p model

This Swedish State railways (SJ) class Z4p was built from a kit made by my good friend Erik Walde. The chassis is scratch built and has a 24x30 Mashima motor with a flywheel. The power is transmitted through a rubberband and normal worm gears. 1:45 scale, 19,0 mm gauge.
Z4p no 321 is one in a series of 41 vehicles built for SJ in 1950-53 by Kalmar Verkstad.

Here the chassis as a 3D model made in ProEngineer.
