Erlian, China isn't much to write home about. It's a border town in a desert, and if the train didn't go through here, it'd be even more of a nothing. It has one interesting quirk, though. Because Erlian is on the border between Mongolia and China, and because Mongolia and China use different gauges of railway track (the tracks are further apart in Mongolia), they change the wheel assemblies in Erlian. 

Hard to believe, but true: they pull rail cars (in pairs, in our case) into a big garage, disconnect each rail car from its wheels, lift the car, roll the wider-set wheels out from under the car and lift the wheels out of the way, roll in narrower-set wheels, lower the rail cars onto the new wheels, and (hopefully) attach each rail car to its new wheels. I'd read about this somewhere, and I was hoping we'd be allowed to watch and take pictures. Happily, the staff didn't object, as you can see.

Not surprisingly, this whole process takes a while. Some of the time required to cross the border was tied up in showing passports to border authorities in two countries, but we spent only about an hour on the Mongolia side of the border, while we spent four hours, more or less, on the China side.

You may be able to learn more at, but I'm basing this guess on the summary that is visible in because I can't view the page. When I try, an error message in Chinese appears. I can't imagine what that might mean.

Re: Narrow gauge
How I would love to be able to hear that song right now. I brought no music with me on my MP3 player, only Chinese lessons, but if I'd had the time to rip a few CDs to MP3s, Assassin's Apprentice would surely have been among them.
