  • Berkeley was not only the first city in America to use racist zoning to prevent lower-income and non-whites from moving into wealthy neighborhoods – but the Elmwood district was the first neighborhood in the city to receive such treatment. That 1916 plan persists basically unchanged to do this day, with the Elmwood having the highest percentage of white residents in Alameda County. The State is acting well within its obligations to put a stop to such policies.















  • Even if same train, it is not run under the same regulations. The US FRA regulations really kneecap the operational speeds:

    For the track between New Haven and Boston, [Acela] has a waiver for operation at 7 inches of unbalanced superelevation. This means, that the [tilting] Acela is allowed to use the same curve speed as non-tilting TGVs (or multiple units) in France. The “Acela Express” looses about half an hour between New York and Boston, compared to best practice in tilting train usage. (It also looses at least half an hour, compared to the calculations of US railroad engineers in the 1960s.)

    Note that the above was written about Acela 1. The Acela 2 is supposedly lighter weight, so in theory FRA might allow higher speeds (though I have yet to see any progress there).





  • According to the bog-standard UIC definition, HSR requires dedicated HSL running generally at 155+mph. UIC has a second definition that does allow for upgraded conventional lines running generally at 125mph in corridors without air competition. Acela meets neither of these metrics.

    Even aside from the air competition issue, Acela’s general overall speed is not over 125mph or even 100mph due to all the slow sections. For example:
