I took some pictures of this rail this morning on the way to work. If you know Newcastle/Gateshead, it’s just near the Millenium Bridge, on the Gateshead side.
For sure this is a do-able rail, one that I could perhaps ride myself, or at least try. It would be a boardslide. Having said that, it is pretty steep and straight on to flat which could be tricky/painful… perhaps there’ll be enough snow this winter to try it out?
