Railway Incident Scenario

You are responding to a call from network rail. They have reports that one of their drivers has hit a person who was on the tracks. He thinks it was only one person but you have no further information than that. The job is only 5 minutes away from your location. There are numerous other resources on route including British transport police, HART, and an enhanced critical care team. As you make your way, you come underneath a bridge where you see the front of the train that has stopped. Someone is waving at you so you stop. They have stated that the patient is 50m away from you location and you can get up onto the tracks via the grassy bank nearby.
