Thinking about how to save money.
There are a couple components of the WLTC that probably can't be moved. A west loop subway probably does have to happen under Clinton. One station on this line would probably be located at Monroe. This station would connect directly to the Monroe transitway, and via a concourse to Union Station and Ogilvie. So that's 2 levels: tracks/platforms, plus the concourse/mezzanine.
As for the other two levels:
The "Clinton Transitway" (aka busway) - does that really have to be below ground? Who knows.
For HSR, though, there are numerous complicating factors that make it difficult to run HSR trains to the WLTC under Clinton. First, the HSR trains are envisioned on the bottom level, which would make the approaches extremely long and expensive. Also, how do you power the trains when they're in this tunnel? Dual mode trains? Do you build an expensive but probably still imperfect ventilation system? A 4-level escalator to reach the HSR platforms seems extreme, too. And how many HSR tracks/platforms can fit under Clinton anyway? The renderings I've seen show apparently just 2 tracks and 1 island platform. Dedicated HSR platforms and lead tracks increase speed and efficiency, but is it worth all that expense?
The easier and less expensive (but also less flexible) solution would be to rebuild union station to have more through tracks. Through-routing commuter trains would free up some slots, making Metra more convenient to boot. This does come with its own set of issues though, not the least of which is that there are only 3 tracks on approach to Union Station from the north and that could severely restrict capacity. In addition, this would cause the added expense of condemning and demolishing 222 S Riverside.
So, to summarize: which one will cost less: a 3-4 level WLTC with expensive approaches for HSR, or a 2-3 level WLTC PLUS the union station reconfiguration. And, how do you deal with the complications of each?
