LokPilot 4 Micro Conversion of 3426 Railcar

Date: 05-02-2012, Corrections 22-07-2012
Hi All,
My friend Rudolf asked me to convert his Märklin Delta 3426 Belgian Railcar using a LokPilot Micro
V4.0 decoder. He wanted to improve the lighting effects for the cabin, front and rear lights. The
locomotive should have prototypical speed of 80 km/h. The results proved worthwhile and Rudolf’s loco
is back on his favourite list.
Warning: - You undertake the following modifications at your own risk. Mechanical modifications will
be required to make the locomotive quieten down a little.

This locomotive designed by Trix, is very noisy, one could say it sounds like a coffee
grinder. Read on to find out how I made it run much smoother and reduce the noise.

Mechanical and Electrical Requirements for the Chassis
First I stripped the locomotive down and
removed the driving bogey. I removed the
wheels to allow me to get the two rubber tyre
wheels on one axle at the back of the bogey
(yellow arrows) and have the plain wheels at
the front for track contacts. I made sure to get
the wheels quartered for the drive shafts to
operate correctly.
Next I dissembled the bogy block so I could
clean all the gears and re lubricate them with white grease containing Teflon. All gear axles that went
through bronze bearings were oiled with light oil and then the drive bogy was reassembled.
General Chassis Arrangement
Front
Rear
With the old Delta PCB removed I was left with 0.5mm gap under the interior seating
which I filled by gluing 3x0.5mm wood strips down both sides of the chassis. To help
keep the wires neat and tidy I glued a parallel strip with a small gap to create a channel for
the wires to sit in. Black electrical tape was used to help hold the wires in place.
Front and Rear Light and Power Connections
The locomotive has front and rear light change over so requires a (F + R + +Pole) at each end. The blue
+Pole is the lower connection on the light assembly at each end. Wires should be long enough, as seen in
the general arrangement.
For the power (centre rail) and ground I glued a small piece of Vero board (3foils x 3 holes) with hot melt
glue and soldered the existing black wires on the right hand side and soldered two new ESU wires (red
and black arrows). The two wires should reach the front of the loco plus add 100mm for connection to the
interconnection panel.

Chassis Ground Solder Lug
Temporary fix a solder lug
for the chassis ground
connection as shown.
Solder the black wire (violet
arrow) from the rear power
Vero board to the lug.
Solder the black wire (orange
arrow) from the
interconnection panel to the
lug.
Solder the black wire (yellow
arrow) from the wheel
contacts (original wire) to the
lug.
Note: - when the interior is
fitted this screw will have to
be removed and the lug will
be held by the interior fixing
screw.
Motor Connections
I connected the grey and orange wire for the motor as shown.
The length should reach the front of the loco plus add 100mm
for connection to the interconnection panel.
For the motor connections leave the wire long enough in case
you have to change sides to get the correct direction for
forward.
You will also notice I scratched a small “T” (yellow circle) to indicate the top of the motor as it was used
for the Delta decoder for the forward direction. If you remove the motor, it can be orientated for the
correct direction upon reassembly.

Interior Modifications
The interior insert needs to have some slots cut into it to allow the wires to be easily removed when
servicing the locomotive (see general chassis arrangement).
Wiring Arrangement Details
Lay all the wires from the chassis into the slot and
using the Interconnection Panel wiring (next page)
trim the wires to length and solder the wires as
indicated.
Photo bottom left shows the decoder placed into
the interior hollow and the lower right photo
shows the interconnection panel finally in place
with all the wires nice and neat.
The wires are behind a window pillar and below the window level so that no wires can be
seen when the locomotive body shell is on.

Protoboard (Vero Board) Interconnection Panel
The interconnection Vero board size is (4 foils x 11 holes)
Yellow circle indicates 8x 2mm counter bore holes to
allow 2x SIL sockets (4 pins each) to sit flush with the
Vero board.
On the foil side use a 3mm drill to cut the foil at the
location marked with a green circle with a cross.
Use a Dremel with a cutting disc to cut all foils as shown.

The interconnection panel above shows connection points for all the wire colours.
CL=Cabin Light, R=Rear Light, F=Front Light.
Solder the SIL sockets x2 to the Vero board with the decoder harness plugged in to help hold the sockets
in place. Cut the pins on the foil side for a low profile.
The 1k resistor and the two 1N4148 diodes are for the cabin lights only as the bulbs have been exchanged
for warm white LED’s.
Warning: - Check with a multimeter that there isn’t any connection between wire colour connection
points and adjacent SIL sockets.

Interconnection Panel Wiring Harness
Insert the colour wires as indicated through the holes on each sides of the SIL connector making sure you
have a suitable length and solder to the Vero board foils, trim the soldered ends for a low profile.
Now plug in the decoder making sure the wire colours match the location of the wires next to the SIL
connectors. Position the decoder as shown above making sure all wires are within the locomotive chassis.

Remove the light diffuser and the existing soldered light bulbs and replace with 3mm warm white LED’s
with the orientation shown above. The LED’s will be connected in series.
Remove the silver light baffles to improve the light level and bend the LED’s in the same direction as the
old bulbs and then refit the light diffuser.
Note: - Cut the PCB track located at the red arrow position. Solder the blue and green wire at the
indicated locations.
Carefully fit the light PCB in place as shown.
Trim the Blue (+Pole) wire from the interconnection panel to length and solder at the location
(blue arrow) on the light PCB.
Trim the green wire from the interconnection panel to length and solder at the location (green arrow) on
the light PCB. Use a small amount of hot melt glue to hold the wires in place.
Clip on the body shell and we are ready to programme the decoder.

With the above Lighting Control CV configuration the cabin light increases in brightness using “Rule 17”
when the locomotive moves.
The final results were well worth the
effort both in looks and improved
running.
All original parts have been kept to
allow someone to return the locomotive
to its original state.

Left is the speed
profile showing all

settings of Rudolf’s
railcar.
Rudolf approved of the improved smooth running of the locomotive, a result of good lubrication, nice
warm LED lighting for the cabin that uses “Rule 17” which dims when the train isn’t in motion and he
was also happy that the noise had noticeably reduced.
As always enjoy your model trains.
