Mark VII will traverse the system’s 2.5-mile route using coaches with remodeled nose cones, seats facing outward and blue glass with stripes.

Those yearning to ride Disneyland's long-awaited new monorail found they had to hang on a little longer Saturday. The Mark VII, which had appeared off and on late in the week, never made it out of its shelter, to the dismay of some visitors hoping to step aboard.

The Mark VII, otherwise known as Monorail Red, is the seventh generation of the ride that's been entertaining visitors since 1959 when it made its entry as the nation's first electric train system on a single rail.

Sleek and futuristic, it was promoted as a vision for public transportation.

On Saturday the long-awaited new train, the park's only upgrade of the attraction in 21 years, failed to appear after several hours of on-again, off-again operation over the previous two days.

Disney officials attributed the glitches to the attraction's normal "test and adjust" period, when mechanics and designers work out the bugs.
