this be a very good cartoon that i intend to watch many time more in the future and but for now i will publish these modest comment base on my experience of have see it only once . what strike me a shock about porky railroad be it absolutely even brutally and i should say honest depiction of the soul of man under capitalism to paraphrase the title of that famous book by oscar wilde which i unfortunately have not read yet . the first shot establish the state of the art in train one that would look modern even by today standard . then and the film switch to porky obsolete and barely functional model . it be interest then how the film establish porky character a sentimentally attach to his old train and but not anti technology at all represent for him and machine have precedence over animal . the race that ensue be the necessary conflict that precede the shocking and of an unbridled cynicism end that carry to the last consequence the truism that sentimentality have no place in a technological capitalist society porky win the race but be not allow to keep his train while instead he be promote to machinist of the new one and and be soon burst with joy . obsolescence happen to train as well a to people the old machinist go to the garbage can just a porky old train .
