Charlie, I can agree with that.
The locomotives have printed circuit boards. When they were updated the old style went into the trash. I found out that a small one, about the size of a cell phone cost $500 to $1,000. The largest was about the size of the CDC calander cost $4,000. to $11,000. The company would buy them back at 50%, do an update and resell. A burnt board was trashed. The company would buy them back at 20 to 30%.
I received $100 for this recycling idea.
