In 1963 British Rail had already established its standard track construction of continuous welded rail secured to prestressed concrete sleepers by ’resilient’ clips. Since then, passenger train average speeds have risen by up to 50km/h and freight train axle loads have reached 25 tonnes running over the same track as the High Speed Trains. This has been achieved with the minimum of improvement to the track structure.
