The takeaway

The staggering $90 billion cost increase for California's high-speed rail project raises serious doubts about the project's long-term viability and whether it can be completed as originally envisioned. The dramatic overruns will likely lead to intense political and public pressure on the state to reevaluate the project's scope, timeline and management.
