You could but
(a) the electricity would be generated where the train is, so would not be readily available at any one place (assuming you intend turbines to be mounted on the train; if they are on the ground and generate electricity as the train passes, you would need incredibly long trains to generate any meaningful amount of electricity);
(b) more energy would be used in creating the train's motion than would be generated
