Essential Sudoku DS: transportation

Up to puzzle 679 now, which means that I'm over two thirds of the way through the game. It's only taken me a year and a half. At this rate I might have completed the game by the time the DS2 comes out.

Oh, and the last puzzle I talked about didn't require guesswork. It did mean I had to develop a new technique, though, of using different colours to progress down a path until it was proven to be a dead end.
