Underneath the Arches...

... lies a little piece of modern history. This viaduct is on the Leeds York line and crosses the river Crimple Valley on the outskirts of Harrogate.

Some decades ago ICI researchers based near here came up with a new material which would transform our lives, or at least it would at that time. This new material needed a brand name, so (guessed it yet?) CRIMPLENE entered our lives.

I guess a fair number of blippers won't have a clue about what this is about; of course I was very young at the time...!

My effort for this week's challenge Underneath! Maybe worth looking at the large version to see the train chugging along.
