These two TGV Atlantique trainsets are waiting at a platform in the
Montparnasse train station in Paris. You can see that the high speeds take a toll on
the trains, leaving scratches and streaks of a type that you would usually be more likely
to see on aircraft. They are washed regularly, though.
The trains simply back out of the station when they depart; they have driver’s cabs (and
locomotives) at each end.
