Even though it is only a summary of the story, it still describes certain details such as the type of trains that collided and the number of people that died. In this case, those details worked for this particular lead because the fact that a freight train collided with a rush-hour commuter train shows that obviously many people were involved and the fact that it states the number of people that died also catches reader's attention.
