High-floor in the context of "Front-engine, rear-wheel-drive layout"

A transit bus (also big bus, commuter bus, city bus, town bus, urban bus, stage bus, public bus, public transit bus, or simply bus) is a type of bus used in public transport bus services. Several configurations are used, including low-floor buses, high-floor buses, double-decker buses, articulated buses and midibuses.

These are distinct from all-seated coaches used for intercity travel and smaller minibuses, for more flexible services.

A coach (also known as a motorcoach or coach bus) is a type of bus built for longer distance service, in contrast to transit buses that are typically used for shorter journeys within a single metropolitan region. Often used for touring, intercity, and international bus service, coaches are also used for private charter for various purposes.

Deriving the name from horse-drawn carriages and stagecoaches that carried passengers, luggage, and mail, modern motor coaches are almost always high-floor buses, with separate luggage hold mounted below the passenger compartment. In contrast to transit buses, motor coaches typically feature forward-facing seating, with no provision for standing. Other accommodations may include onboard restrooms, televisions, and overhead luggage space.

A low-floor bus is a bus or trolleybus that has no steps between the ground and the floor of the bus at one or more entrances, and low floor for part or all of the passenger cabin. A bus with a partial low floor may also be referred to as a low-entry bus or seldom a flat-floor bus in some locations.

Low floor refers to a bus deck that is accessible from the sidewalk with only a single step with a small height difference, caused solely by the difference between the bus deck and sidewalk. This is distinct from high-floor, a bus deck design that requires climbing one or more steps (now known as step entrance) to access the interior floor that is placed at a higher height. Being low-floor improves the accessibility of the bus for the public, particularly the elderly and people with disabilities, including those using wheelchairs and walkers. Almost all are rear-engine, rear-wheel-drive layout.

A low-floor tram is a tram that has no steps between one or more entrances and part or all of the passenger cabin. The low-floor design improves the accessibility of the tram for the public, and also may provide larger windows and more airspace.

An accessible platform-level floor in a tram can be achieved either by using a high-floor vehicle serving high-platform tram stops, or with a true low-floor vehicle interfacing with curb level stops.
