In addition to those mentioned in other forks on this thread - There are also scheduling trade offs. One of the arguments against high speed rail is that it places a great degree of emphasis on end to end times, whereas on many routes there are a lot of intervening stops that will render greater capacity per train vastly more useful than higher speeds. Probably not a concern for the given case - but if you're comparing transport options in an abstract sense it's something to be aware of.
