The two parks are to be connected by a 30-mile highway, as well as a high-speed train that will run every five minutes and transport more than 86, 000 passengers a day.
From the high-speed-train tracks, escalators lifted me past a bold new gridded superstructure by architect Jacques Voncke into the glorious cathedral of the original turn-of-the-20th-century station.
While all of these improvements are greatly needed, funding high-speed rail piecemeal and state-by-state instead of as a federal project means that train and track technology may differ.
