I have never been to Kings Cross St Pancras, so don't know whether it was a 3-rail system or a 4-rail system as used on the London Underground where besides the outer live rail there is also a centre rail traction current return, thus the running rails are not part of the power circuit to reduce earth leakage current.
To have survived as she did, makes me wonder whether it was a 4-rail system and she fell across the -210 volt centre rail rather than experience the +420 volt outer rail.
Either way, a very lucky lady.
