A third rail system is a method of providing electricity to power a railway through an additional rail alongside the track (or sometimes between the rails). Third-rail systems supply direct current to power the trains and this electricity for traction current is transmitted to the train by means of a sliding shoe held in contact with the rail. An efficient and integrated transportation system is essential for any developed or developing country. Transport drives productivity, improves the quality of life and, carefully planned, is good for the environment. An affordable, sustainable passenger and freight railway service is a vital component of a nation’s economic success. Railways are the safest form of mass transportation. Each day, the UK rail network carries around 22, 000 trains, many are full to capacity and the demand is predicted to grow by 30% in the next decade. It is essential to get more passengers onto an already crowded railway. The system receives a daily pounding from an ever-increasing number of faster and heavier trains and it's no surprise that a huge amount of the rail system needs to be upgraded or replaced to ensure a reliable, efficient and safe system. Unfortunately, for reasons of safety, major works must take place during prolonged 'possessions' or ‘blockades’ when the trains are stopped and the contractors can carry out their essential replacement programmes unimpeded. Skilled rail contractors using sophisticated machinery are utilised to speed the upgrade programme as much as possible.
