High-speed rail routes from Union Station (Curbed LA)

There’s a myriad of issues involved in getting bullet train tracks into and out of Union Station in downtown Los Angeles. Should the train be at street level? In a tunnel? Or elevated? Or some of all three?

Some activists prefer that route because it would be less disruptive to river restoration efforts, but me thinks adding a big tunnel to a project already projected to cost $43 billion is not likely to happen.

Caltrans says the walls won’t require constant replacement, as is the case with guardrails that are frequently crunched by wayward motorists.
