The Motion Picture Chums' New Idea by Victor Appleton

Frank had never taken part in a scene of greater disorder and excitement. He knew at once that the train had run into some heavy obstacle or had been derailed. A dozen of the passengers were thrown from their seats. Women were shrieking, and the two little children in the seat just behind the one the professor and Frank had occupied were wailing in fright as their mother caught them in her arms and crouched speechless and dazed.

Frank saw that they were not seriously injured. The car had tilted and then, as a great shock passed through its strained woodwork, come to a stop. The frightened passengers were rushing for the doors. One or two men threw open windows and tumbled outside. Frank's first thought was of his new friend. He sprang to the spot where the professor lay senseless and just in time managed to drag him out of the path of the terrified people crowding the aisle in an attempt to escape.
