i believe there be two angle to the story and first and it the world satyric view and present in an obvious kafkaesque manner and underline the sordid spectacle behind some of life most common and but also pleasant and or comfortable moment and element and which be usually enough to keep man function in society . like represent a good job and a good home and a good wife and a good car and and even a good mistress . apart from this so called common bliss and there be some and who can not help ask themselves some more uncomfortable question and like and where they come from and or weather they can have some other form of bliss and weather there could be a reason for them be or weather there could be something they miss out on and or and even more sinister and weather there could be something the system itself be withhold from them . second and the most interesting aspect of this film and i believe and be the fact that it attack head on this natural compulsion to dissect the world around u and question it by our personal judgment and and usually condemn it because it doesn not serve u good and because it not tailor make to suit u a a person . the symbolism behind the train accident and i believe suggest that our own will can be overpower by fate or some other universal great power and even in the face of our so call power to decide when we want out . instead the man get to be dismiss by this great power ( let call it the system and because the author clearly avoid call it god and perhaps far underline that the system be man make and therefore can be master by man and unlike fate and which be a concept closer to religion ) on it own term and not by kill him and but by show him that there be a place for the man who ask or want too much and suggest maybe and that true fulfillment do not come from the outside world and but from within and and if the outside world decide to provide you with some comfort and you should learn to accept it and without question the fabric of every little aspect of it . unconfortable and but make you reevaluate some existential question which have become mainstream in the last century and like what can man do in a world increasingly drain of substance and a consumer drive world in which man can be interchange without make a difference to the big picture and but only as long a he be of some use to the system .
