Starting off from these coarse principles, the modern railroad was developed, a road composed of parallel steel rails supported by ties and providing a track for locomotive-drawn trains or other wheeled vehicles , with its heavy woods resting on divided stone and maintaining prismatic steel tracks that weigh of 45 to 65 kilograms per meter, with all its complete cohort of auxiliary elements: nails , signals, dispositions for rescue, etc.
