A tamper is a self-propelled and highly-specialised railway machine for distributing and compressing stone ballast under rail sleepers, both on newly laid tracks and tracks already in service where voids have formed under the rails due to the constant passage of heavy trains. A tamper works by inserting steel arms (or tines) either side of the sleeper, vibrating and then compressing the ballast underneath to form a firm matrix for track support. Sophisticated measuring equipment on the tamper allows for considerable height accuracy of the finished rails. 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.
