CalTrain runs three blocks from my house. They have been setting up the pole foundations and the poles themselves for at least 1 1/2 years now. COVID slowed things down, like everyone/everywhere else, but you can see signs of progress.
Some affluent neighborhoods along the line have resisted the state long bullet train, but it seems to me that the bullet train will not be going full speed through the neighborhoods, like it will out in the country.
