Non-ballasted track

Non-ballasted track refers to railway tracks that do not use a traditional layer of crushed stones (ballast) to support the rails. Instead, they often use alternative foundations like concrete slabs or embedded supports, providing a stable, low-maintenance surface. This type of track is common in urban environments, high-speed rail lines, or tunnels, where a smooth, durable, and precise alignment is essential. Non-ballasted tracks can reduce track deformation, improve stability, and allow for easier integration with other infrastructure, but they typically require more complex construction and higher upfront costs compared to traditional ballasted tracks.
