In the case of the Acela, the electrification of the New Haven to Boston segment significantly sped up the non-Acela Northeast Regional service from Boston to New York. In fact, the ~2X price difference between the Regional and the Acela to save ~45 mins usually doesn&#x27;t make sense when I&#x27;m paying out of my own pocket (or when the Acela doesn&#x27;t run at a convenient time).<p>I don&#x27;t have a real opinion on California high-speed rail. It&#x27;s certainly hugely expensive and probably depends on whether it makes sense for relatively price-insensitive business travelers as the Acela does.
