Jim,
what about an overhead gantry crane that travels in the two horizontal dimensions, with a grab bucket. That way you can push the barges under the gantry with the tug and then unload. The gantry cranes where I worked at a cement works in NSW Australia took the material to the stock pile. They could simultaneously supply material to the raw mill hopper feed. You could do the same but instead of the hopper feeding a mill it could feed the conveyor to your silo with underneath rail loader. Just my 2 cents worth of ideas. Really like you modelling work and the pond is fantastic. Well done.
