Had a day in the railway which was great. As part of an organized trip we were supposed to go up The Brocken. It's was snowing lightly when we set off but got heavier as we went up. Just over half way up we were told because of the weather the train would not be going all the way up. Our guide organized for us the go on another if the line to Eisfelder. The trip was amazing in the snow and very seasonal. Because of the change we didn't have a food stop so this was a little gruelling. All in all a nice day but a little stressful without food and drink. One tip: get a 3 day travel card a reduces the price by about half!!
