Why do they need to have a special train for each airport?  What&#x27;s so hard about putting them on the regular subway system so people don&#x27;t need to pay a high fare and waste a lot of time in transfers and walking between stations with a ton of luggage?  Have you even been to Penn Station?  It&#x27;s not a short walk from the trains to the subway.  That&#x27;s probably why a lot of people prefer cars.
