PT posted this illustrated phantom tour of the Broadway line by Fraseropolis, which in turn generated a subsequent post on his blog.  It was essentially a detailed response from regular PT commenter MB – worth linking to, given new momentum for a Broadway line because of the federal election.

We need to learn from the two-year open trench warfare that occurred during the construction of the Canada Line, which is a cheap, below-average yet effective subway. Because there will be a design life of the 100+ years, and because it [the Arbutus extension] will generate significant revenue and receive very high passenger counts through several interconnected regional-scale transit networks and realize a profit after a few years, they can afford another $40 million per kilometre for full tunnel boring.
