It's simply tool long to be done. Matt estimated on one of the dev streams (I think that it was the studio showcase) that it would take 18 months (!) if the whole team was focusing on it.
Haha, yeah it'd be nice but 400-odd miles is a little unrealistic to say the very least. A section of the ECML would be nice, maybe London-Peterborough or even York-Newcastle.
