The most important doctrine coming from the federal government's authority over interstate commerce was found in the case of Gibbons v. Ogden, where the court announced the proposition that no state can take any action that would impede interstate commerce.Let's say that in downtown Cincinnati there exists a large hub for trains arriving from throughout the United States. The hub has switching exchanges re-routing the trains in differing directions. Let us imagine for a moment that numerous accidents began to occur within the tracks of that large hub. The state of Ohio studies the accidents and realizes that if they simply require trains entering Ohio to install a larger set of safety wheels 100% of the accidents will be prevented. The state legislature adopts new legislation imposing such a duty on all trains entering Ohio.

• Is Ohio allowed to do this? And what is your legal basis as to why or why can't this occur?
