A 110 mph Upgrade Example for San Joaquins

See links below to an article and website about proposed upgrades to existing Chicago-Detroit Amtrak corridor service on existing tracks, to 110 mph standards and other improvements, all for less than $3 billion.

As shown by the Chicago-Detroit corridor example, with the addition of a Bakersfield-Los Angeles route via Tejon Pass–34 miles shorter than via Tehachapi–conventional upgraded San Joaquins could travel from Sacramento or the Bay Area to Los Angeles Union Station in ~4 hours, 45 minutes versus ~3 hours for 220 mph non-stop express high speed rail, or 3 hours, 30 minutes+/- for a high speed “all stops local.”

But CAHSRA wants Calfornia taxpayers to spend another $50 to $100 billion on top of the $10-$12 billion+/-  a combined San Joaquin upgrade/Tejon route would cost to save a maximum of 60-90 minutes per trip. While 3.0-3.5 hour travel times are needed to effectively compete with air travel between Sacramento/Bay Area and Southern California, they are not needed to compete with most intercity trips, which are made by automobile.
