Bullet trains sometimes duplicate existing rail

California's high‑speed‑rail project is building a new, expensive Central Valley segment that overlaps current Amtrak routes and even replaces existing stations, forcing transfers rather than providing net new direct service. Contracts and site evidence show the current work stops short of Bakersfield and that some demolished Amtrak infrastructure will not be immediately replaced by continuous service. — This reframes high‑speed rail debates from 'build versus don't build' to asking whether particular projects are net additions to mobility or redundant replacements that waste public funds and disrupt existing service.
