**Update**
It turns out one guy from my office was on the train, he suffered severed tendons in his hand. His brother-in-law, who was with him, dislocated his hip. They both had to wait 4 hours to get to hospital as the more seriously injured were most likely taken first. I've heard unconfirmed reports that an 8yr old girl, daughter of a family connected with one of my colleagues, was one of those killed
