Some of the EBT served mines did use electric mine motors. After the EBT and the mines closed down, some of the mine motors were stored at the engine house in Robertsdale. I have no photos to share, but there are photos showing the mine motors sitting out of service. Today the motors and the engine house are long gone, unless one is sitting in one of Kovalchiks scrapyards. I don't think any individual motors were identified, so you would have to know what you were looking for. Not a lot of help, maybe someone else can chime in.
