Here's a video from 2013 about a coal delivery from Bottrop via Hagen to Werdohl. No need for a diesel shunter ... the tracks at power plant Elverlingsen where fully electrified. Werdohl -> 27:00 Min. Power plant -> 36:00 Min.
Very interesting. I was driving the route today, and wondered how on earth a train could ever enter the power station. I had no idea reversing on the mainline was even possible like this!
