The Discworld and the Singapore MRT System

I was just looking through a bibliography of Terry Pratchett's wonderful Discworld novels. That's when I noticed that the titles have an odd synchronicity with the stations of the Singapore Mass Rapid Transit System.

I am quite certain that if Pratchett lives long enough, every single one of his novels will match up, one-to-one, with a station on the Singapore MRT network. If I disappear one day while on the MRT, you will know why.
