Asked by caleb
George Stephenson was a British inventor and engineer who designed many of the first railroad tracks. How did Stephenson's work contribute to the success of the railroad system?
He insisted that all of the tracks he designed conformed to a standard size, which made it easier to connect all the tracks later.
He designed a type of track that could be curved around obstacles more easily.
He build his tracks using a type of steel that would last a long time because of the proportion of iron in the rails.
He worked with locomotive designers to ensure the trains would run smoothly on his tracks.

Explanation: Stephenson promoted and used a standard track gauge (4 ft 8½ in, the "Stephenson" or standard gauge), enabling different lines and locomotives to run on each other’s tracks and allowing a unified, interoperable rail network. The other statements are not his principal contribution: curved-track design and long‑lasting steel rails were not his defining innovations, and while he did build and influence locomotives (e.g., the Rocket), the standard gauge was the key factor in the system’s success.
