In comparison to steel tracks, rubber tracks are lighter, waste less power on internal friction, make less noise and do not damage paved roads. However, they impose more ground pressure below the wheels, as they are not able to equalize pressure as well as the stiff mechanism of track plates, especially the spring loaded live tracks.
Snowmobiles once used cleated tracks, but racing snowmobiles are banned from using cleated track for safety reasons and instead use rubber tracks. [6] Protrusions molded into rubber tractor tire treads are known as lugs, as are cleats for round wheels, [citation needed] which perform a similar function. Unlike metal grousers, these rubber tire ...
For a rubber tire, an analogous energy loss happens over the entire tire, but it is still called "rolling resistance". In the broad sense, "rolling resistance" includes wheel bearing resistance, energy loss by shaking both the roadbed (and the earth underneath) and the vehicle itself, and by sliding of the wheel, road/rail contact.
The tires serve as paddles as the track rotates allowing the airoll to propel itself and even maneuver in water without the aid of a propeller. It is common for the tracks of conventionally tracked vehicles to be fitted with rubber pads in order to alleviate the damage they cause to the surfaces they move over.
The vehicles have wheels with rubber tires that run on a roll way inside guide bars for traction. Traditional, flanged steel wheels running on rail tracks provide guidance through switches and act as backup if tyres fail. Most rubber-tyred trains are purpose-built and designed for the system on which they operate.
A railway or railroad is a track on which the vehicle travels over two parallel steel bars, called rails. The rails support and guide the wheels of the vehicles, which are traditionally either trains or trams. Modern light rail is a relatively new innovation which combines aspects of those two modes of transport. However fundamental differences ...

Modern steel ties handle heavy loads, have a proven record of performance in signalized track, and handle adverse track conditions. Of high importance to railroad companies is the fact that steel ties are more economical to install in new construction than creosote-treated wood ties and concrete ties.
