the first train could be loaded and dispatched for the return. In 1999, the monorail began lengthy periods of closures due to construction of the Disney California Adventure theme park where the monorail beamway passed through what had formerly been the parking lot. Although the beamway's route was not altered, a significant amount of construction was done around the existing beamway, and much of the terrain under the beamway's support columns were regraded, necessitating the closures. Additionally, the Disneyland Hotel Station and all of its nearby hotel structures were completely demolished and a new station built in the same location. Downtown Disney Station is treated as a second gate into Disneyland Park, so a general admission passport or valid annual pass must be presented to ride the monorail and the tail-cone tour is no longer offered. The system resumed limited shuttle operations in 2000 when the Downtown Disney Station became operational, but a significant portion of the beamway was still unusable due to construction. In 2001 the monorail resumed full capacity forward direction circuit operations, passing through Disney's Grand Californian Hotel & Spa, as well as showcasing the new park. In 2004, Monorail Orange was removed from the line and taken to Walt Disney Imagineering in Glendale to be reverse engineered. Monorail Blue was removed in September 2006 for rebuilding. The Finding Nemo Submarine Voyage show building was extended into the lagoon beneath the monorail, which closed from August 21 through late December 2006 to prepare for the 2007 opening of Nemo. Mark VII monorail Like the Mark III to Mark V conversion, the refurbishment from Mark V to Mark VII was done one train at a time. The entire Mark VII Monorail fleet consists of three trains — Red, Blue, and Orange. The first Mark VII train, Monorail Red, arrived at Disneyland on December 20, 2007. It was originally expected to be in service by the end of February 2008, but due to design change issues, it did not begin serving park guests until July 3, 2008. Mark VII Blue arrived on-site on April 10, 2008, began daytime riderless testing on August 1, 2008, and began guest service on September 16, 2008. Monorail Mark VII Orange arrived on-site on August 14, 2008, began riderless testing in March 2009 and began guest service on April 7, 2009.
