Title: Märklin Rail Zeppelin conversion with ESU lokpilot decoder.
Post by: capeklr on August 13, 2018, 09:42:56 PM

Hi everybody,
my next digital conversion is complete.  :)
Märklin rail zeppelin.
The prototype was built in 1929 and designed by a German Aircraft engineer and powered by a 600 hp aircraft engine.
It was built and first shown to the public in the city where I was born, Hannover. Just a bit of useless info.  8)
Originally the Märklin model had the normal three pole AC motor with direction changer and a bridge rectifier for the
second DC motor for the propeller.
The motor was converted to a five pole DC unit, the propeller motor remained unchanged and a Lok Pilot V4 was fitted
with a few vero board to get everything connected.
Front lights where changed to LED.
Rear Led light was also fitted.
I had found a circuit on the net to control the propeller motor via Function 1 from the decoder, but could not get this to
work.
Here's a photo of that circuit.
The resistor is purposefully separate so that I can try to get the best value by trail and error.

When I could not get this circuit to function correctly it landed in file 13.  :peep:
Then I just connected the prop motor parallel to the main motor.
Here is an overview of all the electrics in this train.
Note that I have also here once again made use of a cap for smother running.

The front and rear Led lights.
For the rear I had to file a bit away from the frame to make space for the Led.
The shell has the place for the light, but I needed to drill this out and then insert
a light diffusor.

A few you tube videos of the real thing.

Sorry the second video is in German, but I'm sure you get the idea.
