^Okay, I read the link now. While 893 million euros is impressive, you can't really separate the cost of building the station building from the cost of all of the tunneled approaches, where I expect to see dramatic cost escalation. It's true that the Washington project is exorbitantly overpriced, as is every infrastructure project in the United States, and particularly in the older eastern cities. However, if the price tag can be forgiven (which is admittedly hard), I think this is still a much more worthwhile project than our own Union station renovation which just perpetuates the same mistakes into the future, albeit with an improved subway station and a roomier (but more commercialized) GO concourse.
At least the Washington Union station revamp adds capacity, integrates different transportation systems (notably the bus terminal), and has a forward-thinking approach to intercity rail transportation. It also does something we still haven't done: bury our station and free up the valuable land for real estate development. Our Union station project costs a fraction of theirs, but it still maintains a physical separation between VIA and GO (and does hardly anything to improve the experience of VIA passengers except for the Panorama Lounge), still maintains the Bush shed, still maintains the horrible track layout with its narrow, claustrophobic platforms, fails to better integrate other transportation systems (or even the ones that exist there presently), and still cuts the city off from the lake and from potentially billions in commercial real estate development.
