The life of railway assets is usually in the range of 20-40 years for electrical and mechanical systems and 60-120 years for fixed civil engineering infrastructure, assuming properly managed and regular maintenance.
A traction system that doesn’t use electrical energy for the movement of vehicle at any stage is referred as non-electric traction system. The steam engine drive is the best example of a non electric traction system and it is the first locomotive system used before the invention of actual electric traction systems.
Traction motors and generators every train needs a unique motor or generator for its purpose. Abb holds a complete and flexible traction motor and generator portfolio that allows us to build the perfect solution for train operators – regardless of train type, power range or geographical location.

Elevator cars are pulled up by means of rolling steel ropes over a deeply grooved pulley, commonly called a sheave in the industry. The weight of the car is balanced by a counterweight since 1900. Sometimes two elevators are built so that their cars always move synchronously in opposite directions, and are each other's counterweight.
1 basic definition (a) traction system • propulsion of vehicle is called the traction. (b) electric traction system • the system of traction involving the use of electricity is called the electric traction system. 2 ideal traction system • high starting tractive effort in order to have rapid acceleration.

This series of tutorial articles explains the electrical and control engineering background in electric railways. The articles cover traction drives with dc and ac traction motors, electrification systems, and railway signalling and control systems. This first article covers the nature of the traction load, the requirements of the traction duty cycle and power electronic controlled traction.
