What if Cascadia HSR happened at the same time as the MAX Downtown Tunnel? What if you could put them in the same tunnel? Theoretically, you could use the 'Big Bertha' drill used in the Alaskan Way Viaduct replacement project to make a double decker deep bore transit tunnel to fit commuter/regional/HSR in the lower deck, and MAX in the upper deck. It would only take one tunnel to do as well, just a very expensive one. There is one other tunnel built to connect the red and blue lines to the main tunnel, but they could also just be kept aboveground using the steel bridge if you really want just one tunnel. Better than the last one because it doesn't serve Beaverton and act as a WES extension.
