HSB 99 7237 is leaving the Drei Annen Hohne station to the Brocken summit with a late afternoon passenger train.

This steamtrain leaves Wernigerode and runs to the Brocken, during the steamloc on the left side takes the coals for the next trip

I've "run" all 3 of these locomotives as part of my steam engineer course. Fluency in German is a prerequisite for the course. It's a neat deal.
