hydraulic maintenance

Wander into town to go book shopping and attend the start of the final push for the Berlin, Climate Neutral by 2030 referendum where I will get to vote at the end of the month. For a change it was a nice and sunny day but still cold. We couldn't take the S Bahn into town as they were doing some maintenance (see extra). Luckily we have a choice of S Bahn or U Bahn (for some reason we rarely take the bus). I think this bit is used to jiggle the ballast. Finished book #8 - the next part of the T. L. Huchu Edinburgh Nights series. Really enjoyed it. I suspect it'll take me a while longer to finish the next book.
