Shocking incident - could have been accident - in FCC tunnel on Friday

I'm amazed this hasn't received more publicity - I noticed it in a small piece in today's Guardian - construction workers managed to drill into the First Capital Connect railway tunnel north of Old Street station on Friday morning:

"at 10.09am the driver of the 10.02 Moorgate to Welwyn Garden City service with passengers on board saw muddy water pouring onto the roof of the train north of Old Street station."

"A Network Rail Mobile Operations Manager later joined another driver on board an empty train from Moorgate to investigate the problem and as they approached the area at low speed, two large piling drills came through the skin of the tunnel."

See this story for more - including an impressive photo:

They are apparently trying to fix it over this weekend....
