Only liberals...
or any conservative who has actually lived in Europe, and by Europe I do not mean England. It is possibile to fly into Frankfurt and go from there by train and bus to any place in Germany and not have to walk more than half a mile.Or you can rent a car and get on Autobahn's that are seldom half a full as the Beltway. Did that last spring, and as I swumg onto the Autobahn I asked my wife, "Where is all the traffic?" Nothing near as bad as what I had encountered driving into the airport in Phiuadelphia.
And in those few words, you have hit upon the key to the future of successful passenger rail in this country. "Inter-modalism", as Gil Carmichael likes to phrase it.
The idea is to get passenger trains into our airports and use them for short-haul runs similar to Europe. Even the airports get a lift. It's more profitable to use a landing slot for a high-value long-distance flight than for a short commuter hop that could be efficiently handled by rail.
