it runs on a rail instead of wheels
The wheels have flanges on the inside edges, they keep the wheels on the rail. The wheels would not stay on the tracks without the flanges.
Locomotives and rolling-stock stay on the rails partly by a combination of rail and wheel-rim profiles keeping the wheel-set centred on the track; but mainly by the flanges on the wheel backs stopping the wheels from sliding sideways off the rails.
It is literally a bus that is being put on rail. The construction is almost the same with normal road bus, but the wheels are changed so it can travel on rail track,

Each car of the train on the roller coaster has wheels that grab on to the top, the outside rail (most of them), and the bottom.

A monorail typically has two main wheels that run along a single rail, but it may also have additional wheels for stability and support. These additional wheels are often used to guide the train and can include secondary wheels on the sides or underneath the train. The exact number can vary depending on the specific design and configuration of the monorail system.
