When should you never cross a railroad track?
Never try to make it across a railroad crossing if you see a train coming. The main reason is that it can take a train moving 55 mph over a mile to come to a complete stop if they pull the emergency brake. So there's no chance they can stop if you hit some bad luck and break down on the tracks.
How do trains not derail on curves?
The outer rail is raised to tilt the train to the inside of the curve - this provides roll-over protection and at cruise speeds gravity helps keep the train more or less centered in the track. The wheels are tapered and 'steer' the bogies away from the rails, so on a curve the train is 'steered' around the bend.
How do train tracks not break?
How do trains carry such heavy loads without breaking the rails? Rails are made from STEEL…hardened and tempered STEEL. They sit on ROADBEDS made from STONE/CONCRETE and ties…made from LOGS and or MORE STEEL. The ties are close together.
