Earlier this week, I joined a group on a walk around Wolverhampton looking for the remains of old railways.
More of this later, but one quick surprise find was some broad gauge rail, which is still in use.
Admittedly, it's in use as a gatepost, but that's not bad for metal over 100 years old. Two lengths have been bolted foot to foot and filled with concrete. Painted blue, the post still stands down a path from the Low Level station.
