Did a bit of sightseeing as planned: the Rocks Railway is, to be honest, a bit underwhelming as you can't see down the tracks to the bottom station because there's a World War 2 blast wall in the way (the tunnels were used as an air-raid shelter), but nonetheless interesting, while the caves are much more extensive than I'd imagined, and really quite impressive. Photos of varying quality (as I was aiming the camera in the dark most of the time) can be found here.
