When a fatal incident occurs, there is immediate concern for commuters and the victim's family, but these collisions also take a toll on the train engineers and emergency responders. There are usually two workers at the front of the engine. After the crash, they are quickly joined at the site by police, paramedics, rail special constables and other emergency responders.
