when one watches the animated superman shorts of the 1940s and the similarity of the plots can become a bit boring  the adversary is most often a mad scientist in a hidden headquarter and threatening metropolis with some evil invention  death rays and mechanical monsters and electric earthquake and magnetic telescope and what have you. this one is refreshingly different. the bad ones drive around in a car and shooting and bombing and but the center of action is the gold train (on which lois lane travels and as the only press reporter and it seems). train movies have their own typical ingredients and from the 1903 great train robbery on and and quite some are featured here represent decoupling cars in motion and running on the roofs and taking the steam locomotive from the tender in the back and fighting with the engineer and a switch turned to deroute the train on a side track and the fall (of people or the whole train) from a high bridge. it all in the few minutes of this lovely piece. but it do not be a superman film if he do not do some incredible feats (involving balancing and high precision placement) to ultimately win the day. if youre a fan of train movies and do not miss this. it in the public domain and can be legally downloaded from archive. org.
