The act of drawing, or the state of being drawn; as, the traction of a muscle.

Specifically, the act of drawing a body along a plane by motive power, as the drawing of a carriage by men or horses, the towing of a boat by a tug.

Attraction; a drawing toward.

A term for applying force to teeth

The adhesive friction of a wheel on a rail, a rope on a pulley, or the like; as, the car is stuck in the snow because it can;t get any traction.

In the context of this book the concept of achieving grip between the wheels and the ground without slip, skid or sinkage.

The UTQG traction rating is designed to help consumers compare the wet-road braking performance of a tire. Government guidelines specify the test conditions for testing traction on asphalt and concrete. All tests involve braking in a straight line. None of the tests measure traction while turning, resistance to hydroplaning, traction on snow or ice, dry road traction or any other type of "traction".

The resistance to slippage between the tire tread and the road surface, which is affected by conditions such as moisture on the road surface, and by tire tread pattern and rubber compound.

The term as used in model railroading refers to streetcars, trolleys, and electric-powered interurban lines. They usually contain very tight curves and overhead wiring (functional in some cases) in an urban setting.

In the context of rail transportation and associated modeling, a term generally used to connote electric trolley, streetcar, and interurban lines and equipment.

The term used to describe all prototype locomotives and self-powered cars like trolleys and interurbans that operated by electrical power.

City and suburban trolley lines; equipment run by electricity.

Dragging or rolling of particles on a surface.

Transport of sediment by wind or water in which the sediment remains in contact with the ground or bed of the stream, moving by rolling or sliding. (See suspension and saltation for comparison.)

larger boulders rolling or sliding along the riverbed

Erosional movement of particles by rolling, sliding and shuffling along the eroded surface. Occurs in all erosional mediums (air, water, and ice).
