What is this piece of equipment?
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
