Apparently a rail line in Sussex (at Balcombe) had problems due to an 8ft
icicle in a tunnel.

What is that strange picture artefact just left of centre and dead
straight from the curve of the tunnel above the wall to the nearside
line? On checking again, there seem to be another two further away - one
just below dead centre, and the other a bit longer to the right of it.

If there were only two, I'd put it down to some weird lens reflection,
but the third one kills even that unlikely suggestion.
