THE TRAIN PLATFORM in Celle, Germany, is bustling. It's a sea of duffel and roller bags, parents tending to small children beneath a beaming late-summer Sunday sun. Soon, the high-speed train will arrive and, however and wherever the weekend was spent, it's time to return home.
The train will stop first in Hanover, roughly 25 miles away. It will wind hundreds of miles south through Bavaria and the Alps, five and a half hours, to its destination in Munich. Point A to a distant Point B, simple as that.
But for one passenger in particular, it's more than a simple train ride.
