I've built this model between 1989 and 2000. It was often in "dormant" state, when some parts were missing, or I had no mood to work on it, and started other models too. Soemtimes I did not dare to apply a new technology until I had gained enough experience to try it on this model too. This explains the long construction time.

The V40 electric passes an Austrian type semaphore on the huge modular layout of the
Railway Model Club of Pécs/Hungary.
The model was equipped with a DCC decoder to be
able to run on this layout, as the layout is fully digital. The picture was
taken by my friend, István Gelencsér on November 27, 2004.
The ready made model still unpainted and without motor.
The model from another view.
A newer picture about the model. Now it is equipped with the motor as well.
This was the last picture before painting.
The first steps: the first experimental frame with all components.
Second
attempt to make the Kandó-triangles. The holes were made using the
CNC-Drill machine. After filing to
shape they will be separated from the common bottom and soldered to the main
rod.
The first frame with a temporary motor.
The first frame with gears. Only two wheelsets were driven.
The first frame with all drivers and rods. The rod mounting made many headaches.
They have to enable the first and fourth driver to move 1-1mm (0.04") sideways:
thus the loco can maintain 22" radii.
The other side of the first frame.
The third frame with all gears but only one frameside.
The third frame bottom with cab floors. The bottom cover plate protects the
gears from dust, and keeps the drivers on place.
The frame with motor and drive. The flywheel is still a temporary one, later
a larger one will be mounted. The center crank is exatly on the same place
as the motor crank was on the prototype. The prototype's auxiliary crankshaft
is not modeled however. The other slanted rods are simply cut above the cab
lower edge level, thus the missing shaft is not really visible.
The drivers, rods and the Kando triangle. This is a new version, as the old
one did not allow the slanted rod to swing freely, when the front driver
made sideways movements in the curves. The new triangles are also bit (1mm,
0.04") smaller, than the old ones were. In this picture the cab is lifted
a bit. In its normal position the current collector wipers are invisible
on the top of the sandbox.
The cab parts prepared for soldering. The openings were made first drilling
holes to the corners and cut out roughly by piercing saw. The final shape
was given by swiss files.
The soldered cab end with braces. It was soldered using a small gas torch.
The result shows only very small spots of solder along the soldered edges.
The full cab after soldering. The braces are needed as the cab was made from
0.5mm (0.02") brass sheets that would bend out without braces.
The bottom view of the cab. The end distance holders should have openings
at the headlight holes, as they are exactly at the same height. The top distance
holder has a hole for the roof fixing screw.
The roof with the fan, ventilation superstructure and "stack". These parts
are fixed by screws, while the others are glued.
The roof with all parts mounted.
The roof from another view.
The roof with both pantographs erected. The panto shoes still have here no
position springs. They were added later.
Small parts: louvres, sandboxes, steps, roof isolators, roof hooks and splashers
The cab with the mounted roof.
