Rail Road Repair

There's no track ahead!!! And those idiots at Rambunctious Rails™ couldn't make a train that can stop... or rails that don't break after one use... or literally anything that functions properly... (How do they even make money!?) Regardless, the train must go on, and it is your job to ensure it doesn't crash! Place down rails on the end of a shortening track to prevent it from derailing. You may not know where you're going, but that doesn't matter! Just make sure the train keeps going for as long as you can!
