Rail art

I've been trying to capture this for a couple of week's but the train has been stupidly full thus not much room to maneuverability.
To be honest I don't know why but it seemed to catch my eye each time but I kinda like it.
Who ever does this has got talent for this I think, shame that it's not on a canvas or art gallery wall instead of somewhere dangerous like here on a railway line.

Today has been an ok day in work with jobs being sorted without hassle/passing the buck so to speak :)
