It's a fair bet there's a few sphincters twitching, on the contractors working on the Victoria line 
Wrong sort of concrete on the line.
I note the RMT union are quick to get some capital out of this.

Weird way to sort it out.
They used sugar before it had set. Obviously someone has brains to know what to do in a situation like this. Apparently just 0.04% sugar will alter the time of cement setting by up to double the original. i.e. Concrete that is mixed to set in one hour will take 2 hours if the correct amount of sugar is added.
Clever stuff eh?

Does anyone know how they got it out, did it have to be shoveled, or could the pipe it out? Presume they then did a lot of washing and wet&dry vacing on an industrial scale before checking and drying it all!
