The opening of this film is an establishing shot. It shows us the setting which is the city, trains, cars, roads etc. This shot is accompanied by non diegetic music. There is then a sound bridge as the music merges with the sound of the train. 
When it changes from the establishing to the train, all of the sounds are exaggerated such as the coffee spilling onto the main characters foot and a can being opened. These noises being exaggerated creates tension. The cuts are very short as the man keeps looking at different people with confusion. His facial expressions show us that he is feeling very disorderly. His eyes are always moving and he acts very nervous. When there is a point of view shot it is shown shaking and unsteady to show the psychological state of the character. It shows his confusion. The tension builds as he continues to get confused and begins to shout. It keeps building and the shots get quicker. The train then explodes and the shot is very dramatic and captivating. 
The camera work plays a big part in creating the tension as the close-ups of the exaggerated sounds and the quick changes of shots build it up. 
This opening is very effective. The director makes us want to watch on as we want to know what has happened to the man. The impact of the explosion grabs our attention. The lighting and colour used for the explosion is so bright it captivates our attention.
