The next task was to get the coal into the power plant. I did not want to permanently modify the power plant. I made a coal receiving box that is taped to the power plant roof grill. The coal chute extension is held in place with an old magnet from a hard drive. Part of my design is to be able to remove the coal loader for maintenance. All wires have plugs to facilitate this.
The whole setup works quite well. I have to be careful not to dump too much coal at once so the chain is not covered. Coal is almost never spilled when dumping the cars. I will work on getting a decent video of the operation.
