Highest Railroad in the World

Here's a long thought path, good luck following it:

A couple years ago I came across the writings of Gregg Easterbrook, Brookings Institution visiting Fellow, in the form of his Tuesday Morning Quarterback (8/1/6 new season catchup column), a 5000+ word-length column that comes out weekly on (surprise!) Tuesday mornings during the half-year that the NFL is in session, and covers the action on the gridiron, associated (and not-so) stories, and general goodness. Known as a general time sink and office productivity killer throughout corporate America, it's one of my standby reads on Tuesdays, and I've followed his writing of it from Slate.com (where I first found it), to ESPN.com, to NFL.com (after a run-in with ESPN's Disney corporate types), and now back to ESPN.com.
Anyhow, he's an advocate of rail travel among his other interests, and this week he wrote of a visit he made to General Electric's Locomotive assembly facility in Erie, PA, among other things. The motive power currently under production there includes engines for the Chinese national railroad, which is undertaking construction of a new route from the mainland into Tibet which includes the highest mountain pass crossing of any railroad in the world (official site here; BabelFish use recommended for those who can't read Chinese).
So, on the page of a site meant for wide consumption, what graphic would be used to illustrate the map of the train's route? A caricature of a 20-year-old Amtrak train!
