I will be doing that after this week. Just slammed in the shop getting out orders. I have attached a drawing showing some dimensions. The loader works like this. Two sets of sensors are below tower that look for front and rear of cars as they are pulled under the tower. To start loading a train, when engine is beneath the tower blocking both sets of sensors you push the activation button for a couple of seconds and release. There is a LED light on the bottom edge of tower that will turn on letting you know that the sensors are armed and looking for the next car (ie. coal hopper) As soon as the front of that car blocks the one set of sensors the hopper chute lowers and starts dispensing coal as the car moves though. When the rear of the car clears the back sensors the chute closes and the chute retracts until next car triggers again. And will continue fill cars until either the button is pushed again, stopping the filling of cars or until tower hopper is empty.
