Building an operating Coal Tipple

<p>I have seen one layout with a coal tipple, and I'm trying to explain how I think it works to you.</p><p>So basicly you have a large silo above the tracks; which is probably the most common type of modern coal loader. The silo has a track through it, and there's a conveyor running from the top of it into the hillside behind it. There's an optical sensor between the rails underneath the silo. When you run a train into it, there's an electrical switch that's off for the locomotives.. When the first coalcar is positioned under the silo, you flick the switch to "on". When the optical sensor senses something above it (in this case the coal car) then it activates the conveyor into the hillside. The conveyor carries coal into the hollow silo, where it falls the lenghth of the silo; through a funnel, and into the hopper car.</p><p>When the optical sensor sees nothing, (i.e. the gap between cars) then the conveyor is not on.</p><p>That's how I'm guessing that this works. Someone else probably knows better. Good luck! </p>
