An insulated rail joint is a crucial component within the infrastructure of rail transportation systems. It plays a key role in the connectivity between train tracks, allowing trains to travel on a smooth and continuous track, even when they encounter changes in direction, temperature variations and other adverse conditions. This insulated joint is designed to provide a seamless transition between tracks, avoiding jolts, shaking and misalignment that could affect safety, passenger comfort and the integrity of railway equipment. It is called " insulated" because it is constructed in such a way as to minimize the transfer of loads between the rails, reducing the impact of stresses and vibrations transmitted along the track.
