The Last Prince of Washington: Just last year, eight of the Mount Washington Cog Railway’s 0-2-2-0s roamed up and down the face of the east’s tallest peak in northern New Hampshire. But today, change has come and in 2010, only one of the Cog’s ‘Slim-Princes’ remain in regular operation. Once a day steam still attacks the hill with the fury of thousand yesterdays, because this year its never been more clear that there is no tomorrow.
