The next day we didn't use the car at all. We walked to the Harzer Schmalspurbahn station in town and got on the train for the Brocken.
This is the most amazing train journey that we have ever made. The train starts at about 250m above sea level and ends up at 1125m above sea level at the top of the Brocken.
There was about 2m of snow on the top and there are still two or three trains running every hour...
