This morning, The new Monorail Red (formally Blue) arrived and was placed on the track.
I was there taking photos (check the link below)
Also, Brady MacDonald at the LA Times also has written about the arrival. Check out his article, and Disney provided photos at this link.
FYI, the dates that Brady MacDonald used for the second and third trains were provided by Disney, and seem VERY optimistic. IMHO, do not expect them to arrive that soon..... I would say the second train late in 2008, and the third mid-2009.
