Plain on Rail is a type of railway track construction where the rails are laid directly on the ground without any ballast or sleepers. This method is often used in high-speed rail systems and certain types of light rail systems. The absence of ballast and sleepers reduces the overall weight of the track, which can lead to improved acceleration and speed. Additionally, it can simplify maintenance and reduce the risk of track deformation due to the absence of ballast settling.

The construction process for plain on rail involves laying the rails directly onto a prepared subgrade. The subgrade is typically a compacted layer of soil or a concrete slab, designed to provide a stable and level base for the rails. The rails are then secured to the subgrade using specialized fasteners or adhesives. In some cases, a thin layer of concrete or asphalt may be applied over the rails to provide additional protection and stability.

Plain on rail systems are known for their smooth ride quality, as the absence of ballast and sleepers reduces the amount of vibration and noise generated by the train. This makes them particularly suitable for high-speed rail systems, where a smooth ride is crucial for passenger comfort and safety. However, the lack of ballast can also make the track more susceptible to deformation due to temperature changes and other environmental factors.

In summary, plain on rail is a type of railway track construction that involves laying the rails directly on the ground without any ballast or sleepers. This method offers several advantages, including reduced weight, simplified maintenance, and a smooth ride quality. However, it also has some limitations, such as increased susceptibility to track deformation.
