The Brave Engineer (movie, 1950)

Casey Jones is one of the best engineers there is and it is his duty to get his cargo to its destination on time via train. He sets off but is set back by a number of unfortunate circumstances such as a rain storm, a cow on the tracks, a mad bomber, and finally, when his train starts falling apart. Worst of all, he is on a collision course with another train coming in the opposite direction. After a terrific crash, the man at the train station assumes the worst when Casey doesn't show up but, to his delight, Casey finally makes it to his destination a total wreck but on time (almost).
