I now own a LGB 20232. 02-4-0, I have now converted it to battery RC, It has lights, smoke & sound. How do the LGB sound trigger magnet work. Do I need one & will it fit to my plastic rails & work.
 
The track magnet triggers a microswitch in the loco, which will activate a sound such as a whistle/horn.

If you have connected the battery to the track input, then it should activate.

It should clip into your plastic rails between the sleepers, but you may need to glue it in.

And do you need it? Not for normal operation of your loco, but might be a 'nice to have' feature....
 
Do you have reed switches mounted under your loco?

The LGB track magnet housing has a magnet in one side (the side under the 'LGB' logo). This means you can mount two reed switches under your loco, one either side. As the reed switch passes over the magnet, it closes the reed switch contact, triggering the sound. Convention states the left-side will trigger the whistle/horn, and the right-side the bell, but you do not have to stick to this convention.

Reed switches mounted on motor-block..
 
The under side of the tender has a box on the front wheels to trigger the sound, It has chuff sound but no whistle or bell will the magnet do that .
