A driving force that causes the propulsion of a vehicle is referred to as a traction system. The traction system is of two different types: the nonelectric traction system and the electric traction system.

Non-Electric Traction System

The traction system that doesn’t use electricity at any stage of a vehicle's movement is referred to as a non-electric traction system. Such a traction system is used in steam locomotives, IC engines, and maglev trains (high-speed trains).

Electric Traction System

The traction system that uses electricity in all stages or some stages of a vehicle's movement is referred to as an electric traction system.

ADVANTAGES 
• 3 phase locomotive is worked in very polluted and explosive conditions 
• Cheapest in cost (due to absences of brushes, commutator, and slip rings) 
• Maintenance-free or very less Maintenance 
• Self-starting torque 
• Worked in mountain area without any failure 

DISADVANTAGES 

• Operating under lagging p.f (0.2 to0.4) 
• Arise losses 
• Some p.f correction equipment is required 
• Speed control is difficult (variable frequency driver used in industrial level for controlling) 




Note- Locomotive-

A locomotive or engine is a rail transport vehicle that provides the motive power for a train. 

commutator - 

an attachment, connected with the armature of a motor or dynamo, through which electrical connection is made and which ensures the current flows as direct current. 

Brushes -

A brush is a device that conducts current between stationary wires and moving parts, most commonly in a rotating shaft
