London's Heathrow airport gets a new terminal with a great train station link

According to this article in Fodor's,

[The new terminal has] Its own dedicated railway station with 6 platforms, two for the Heathrow Express, two for LU Piccadilly Line and two which are built and safeguarded in advance of a scheme to link Heathrow by rail to the outerlying areas.

That's what we should be doing with every new terminal built in the United States at our airports.
