1) During this period the track structure has been substantially improved.
One of the greatest improvements was the elimination of rail joints. In
order to reduce the number of joints the rails are welded into
continuous lengths.These continuous or long welded rails have greater
strength and provide a smoother running of trains at far greater speeds.
2) Another improvement which has made it possible to increase speeds on
railways is the use of concrete sleepers. Thus in some countries ,
concrete sleepers have replaced wooden ones on heavily used main lines
because of their advantages.
Concrete sleepers have a longer life
and a far greater weight than those made of wood. The greater weight of
concrete sleepers provides the greater stability of track.
It is this factor which has greatly contributed to increased speeds.
