On a steam locomotive, a driving wheel is a powered wheel which is driven by the locomotive's pistons (or turbine, in the case of a steam turbine locomotive). On a conventional, non-articulated locomotive, the driving wheels are all coupled together with side rods (also known as coupling rods); normally one pair is directly driven by the main rod (or connecting rod) which is connected to the end of the piston rod; power is transmitted to the others through the side rods.
On Diesel and Electric locomotives the driving wheels may be directly driven by the traction motors. Coupling rods are not usually used, and it is quite common for each axle to have its own motor. Jackshaft drive and coupling rods were used in the past (e.g. in the Swiss Crocodile locomotive) but their use is now confined to shunting locomotives.
On an articulated locomotive or a duplex locomotive driving wheels are grouped into sets which are linked together within the set.

“You do me wrong to take me out o th grave:
Thou art a soul in bliss, but I am bound
Upon a wheel of fire, that mine own tears
Do scald like molten lead.”

“On a late-winter evening in 1983, while driving through fog along the Maine coast, recollections of old campfires began to drift into the March mist, and I thought of the Abnaki Indians of the Algonquin tribe who dwelt near Bangor a thousand years ago.”
