The WW2 under-Thames casualty was the direct hit on an unused bit of the
Northern line.

There was also an incident in 2012 when a Bakerloo train "hit a tunnel", which
I think meant that some extremity on the train hit a piece of quick-dried
cement grout that had been applied in overnight maintenance, but had oozed out
before it had dried.

"Geoff Martin, an RMT spokesman, said: "There has been a build-up of rain water
behind the tunnel wall and on the ceiling of the tunnel as well. "

Rain from when, the ice age?? Another RMT rocket scientist keeping us informed.
