Hi everyone.

I've had a modest interest in railtrack for > 50y, but saw something yesterday I didn't understand.

Under the edge of the platform, on the vertical wall, there are a series of what look like sliders on an audio mixing desk - but much bigger. I'm not sure if they are actually connected to a potentiometer, or are merely adjustable to indicate - perhaps - track height.

Would be interested if anyone can tell me. I attach a photo

many thanks

Philip
