OK, this isn't a warehouse, or even a building, but this sight intrigued and I suspect some blog reader can probably enlighten me as to what is going on.
Between the tracks for platforms 1 and 2 at Reading station, there is a marked difference in the track levels. Platform 2 is very slightly higher. To accommodate this, a small concrete fence made of posts and panels retains the ballast.
I've not seen this before and don't understand why it's set up like this. The height difference is very small, smaller than many steps down from a train. Both platforms are in use. Platform 1 does appear to have wooden sleepers and 2 concrete.
Why not just build up the ballast for the track in platform 1 and have them at the same level, surely easier than sinking a fence.
It's a mystery to me, but I suspect not to everyone. Please explain in the comments.
