This depends on which "Skyliner" you are referring to, as there are two famous systems with this name. The Keisei Skyliner in Japan is a high-speed train that connects Narita Airport to central Tokyo. While it is very fast, reaching speeds of 160 km/h (100 mph), it is technically not a Shinkansen (bullet train), as it operates on narrow-gauge tracks rather than the dedicated high-speed Shinkansen network. In contrast, the Disney Skyliner in Florida is an aerial gondola system (essentially a "ski lift" for a theme park). It is definitely not a train of any kind; it moves at a leisurely 11 mph (18 km/h) to transport guests between resorts and theme parks. If you are in Japan looking for the "true" bullet train experience, you would look for the Shinkansen, whereas the Keisei Skyliner is a specialized "high-speed express" that offers a similar level of comfort but lower top speeds.
