Brilliant - I love the Swinton picture, although it does boggle the mind somewhat.
I did notice the fast lines and I've been aware of their existence as I've known the tunnel under my house here still exists for the fast lines and evidence of their existance can still be found, I've never seen a picture before though. I had no idea there was a crossover at Swinton there for example, just brilliant stuff.
Thank you very much for these pictures, it's very appreciated.
