Double-decker bus
With the exception of coaches, double-decker buses are uncommon in the United States. Many private operators, such as Megabus, run by Coach USA, employs double-decker buses on its busier intercity routes.
The Deuce (transit bus service)
In 2006, the RTC announced that they purchased 40 more double-deckers that arrived in Spring 2007, and another 40 that arrived in 2008. These new vehicles replaced the original 50 that have been serving the Strip. The original vehicles were reassigned to local routes (height permitting). These new Deuces are special in that they have 2 staircases, one in the current position, and a second one in the back. They are also 2 feet longer than the present double deckers, and have earned the nickname "Superdeuce."
