(OK, none hurt, none even close to being hurt.)
It could have been so much worse. The car rolled through a fence onto the platform and caught the back of a departing train, 'slightly scuffing' a carriage, and coming to a halt. If the train hadn't been there, the car would likely have rolled over the platform edge and been left grounded hanging over the gap. If one of the Cambridge Clippers (non-stop Cambridge - London) had come hurtling through, well, that would have been extremely messy.
