Amtrak holds its own "Super Sunday" every year during Thanksgiving weekend with a number of extra holiday trains.  For the past few years we've experienced cloudy and rainy weather, but 1999 gave us a perfect photographic day.  Evem as this is being written, final testing for electrification of the Shore Line (New Haven, CT-Boston) is being completed and by next year we'll be seeing Acela service equipment pulled by AEM-7s or maybe even something more exotic.  Guilford Interlocking in East River, CT is almost one half mile in length, with long,  movable point crossovers.  Amtrak train 173 negotiates the crossover at 70 mph.
