Hi all,
I recently completed a project to add subdued interior lighting, table lights, kitchen lighting, corridor lighting and a controlled pantograph on an SBB Speisewagen. I finally worked out a way to control the panto.

Some photos then a video.

These show the general layout of the lights and electronics. The magnet held near the wagon closes the mini reed switch, puts a 120 ohm resistor across the decoder orange and grey wires ( ESU lokpilot) which are not used in this case. This allows the decoder to be interrogated on a programming track. It should not be permanently wired as it would become very hot indeed if the throttle was opened.A red LED was used for the kitchen and the corridor is lit by small white LEDs on a flexible strip.

The small geared motor is supplied by the tiny step down regulator and runs at 3 volts. It has an aluminium flywheel attached with a pin mounted on it's external face 2 mm off centre. A small wire passes up through the roof to the base of the panto arm. Momentary actuating F1 controls the motor and when it turns it pulls the arm down. F1 is released when the panto is down. If it is pushed again the motor continues in the same direction and the pantograph spring draws the arm up.



Hope that works, my first video.
Thanks for watching.
Regards,
Howard.

Very smart.
Professional looking construction. 👏
I don't think Marklin would have done better.
This one is for the"keep" file, if you allow us to eventually and shamelessly plagiarize your tricked out speisewagen.
Cheers

I agree, very nicely done. I think the only difference I would have made is to have the three different sets of lights on different functions, so they didn't all come on and off together. Very nice motor and gearbox for the pantograph operation. Operates at a believable speed.

Thanks for the comments and feedback.
I used an ESU decoder and I ran out of functions, f0 inner lights, f1 panto, f2 table lights. Couldn't think of anything to do with the throttle!
Cheers,
Howard.

You can use a LokPilot fx decoder that does not support motor but it has two outputs more.

Aha you have outed me!
In the interests of brevity in my post I didn't mention the background to the decision to use a Lokpilot and not and FX.
I originally decided to control the panto motor with the throttle and be able to reverse it but I was half way through the project and I got a bit uneasy about variable speeds of the panto and it was a bit cumbersome. I decided to have a fixed voltage available from f1 and regulate it down to a fixed 3 volts.
It was then necessary to connect all the internal lighting to f0 and leave the table lights on f2. That left me with an unused motor output but I couldn't use it for anything. ( maybe a moving waiter serving diners? )!! Good project for you.
The only need for the resistor across the orange and grey wire through the reed was so I could address the decoder at a later date if required without taking the carriage apart.
I promise to try harder next time.
Cheers.
Howard.
