A wheel is a wheel.
The sets of wheels under cars are called trucks.
Under a locomotive, they can be "pony trucks", the unpowered, smaller wheels at the front of steam engines to help with guidance, or they can be "trailing trucks" found on the larger steam engines to help support the large firebox. Sometimes these are in fact powered, and referred to as a "booster engine", that provided a little extra tractive effort when trying to start a train.
The other larger wheels are called "drivers", which put the power to the rail.
There is also the "brake wheel", a device used to operate certain types of hand brakes.
There are forms of paper work referred to as "wheelers", a type of train consist reporting.
There is slang terminology, to "Get a wheel on 'em", meaning getting the train up to speed, usually 60 mph or more.

Wheel, but I am sure I have heard of another name as well. Disc wheels are solid & wagon wheels are spoked. I know the wheel is made up of 2 parts. The rim is the centre harder casting & the tyre is the replaceable softer outer metal. They are made in this way so that flats can be repaired & eventually replaced while not damaging the more expensive rim. A flat is the name for a flat spot on the wheel that is caused by heavy braking as the wheel skids on the rail. A truck is a set of wheels under a short rigid rail vehicle. A bogie is a similiar set of wheels but the vehicle sits on two sets of pivoting bogies for longer vehicles. A truck is a goods carrying rail vehicle & a car is a passenger carrying rail vehicle. Hence the Melbourne Tramcars.

a wheel is called a wheel.
A truck is the entire assembly, usually containing 4 wheels, the motor and current collectors if third rail powered. The train is then placed on the truck. On NYC subway cars, the car rests on the truck. It is not actually bolted on. The wieght of the car holds the car in place.

The wheels are mounted on bogies, and at the back there is an extra bit that slots behind the rail. This is called the flange.
