Abstract
A rail assembly including one or more rail bodies formed for supporting rolling engagement of a train wheel thereover, the rolling engagement generating vibrations in the rail body. The rail assembly includes one or more boots formed for attachment to the rail body to substantially electrically isolate the rail body relative to ground material. The boot includes a chamber wall for at least partially defining a chamber between the rail body and the chamber wall when the boot is attached to the rail body. The rail assembly also includes one or more inserts positionable in the chamber, at least a part of the vibrations being transmittable to the insert when the insert is positioned in the chamber, for dissipation of at least a proportion of the part of the vibrations in the insert.
