The present invention provides an adaptive vibration isolator. The adaptive vibration isolator includes a hydraulic system, a first elastic member, a second elastic member, an upper top plate, and a vibration energy consumption device. The hydraulic system comprises a hydraulic cylinder, a piston and a piston rod, a first though hole is formed on the piston, and the first hydraulic chamber is communicated with the second hydraulic chamber via the first through hole. An upper top plate passes through the piston rod and the piston from the transmission portion and is connected to the vibration energy consumption device to drive the vibration energy consumption device to move relative to the piston and adjust the effective aperture of the first through hole.

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.

The present invention relates to elastomeric polymer compositions comprising an acrylate and the reaction product of an acetoacetylating agent and a polyol. In particular, such elastomeric polymer compositions can be used in railway track structures. The invention also relates to a method for applying the elastomeric polymer composition in railway track structures, in particular, the method of applying the polymer composition may advantageously utilise a C-Michael addition reaction which is facilitated by the reaction product of an acetoacetylating agent and a polyol present in the polymer. The invention further relates to railway track structures and systems comprising the elastomeric polymer compositions.
