The boy who continued to sleep on the track until the train passed

It seems that a super express that passed as fast as the Shinkansen passed over the boy who was sleeping on the track. I thought that it would be a catastrophe and said the boy was unharmed. Even after the train passed, the boy did not seem to get up, so he did not know whether he was asleep or losing consciousness.

Details are from the following.

It seems that we finally stopped at 900 yards (about 820 meters) a boy lying down.

After stopping, the driver immediately got off the train and rushed to the boys' race, as the boy was intact and there was no appearance of getting up at all, the fire brigade brought to the hospital just in case.
