A rail damper including an elongate damping device and a clip for
supporting the damping device, the clip having a retention aperture for
receiving part of the rail and, further, a recess adapted to receive the
damper. This is particularly (although not exclusively) suited to dampers
in which an elongate hollow rigid section encloses a deformable material
in which is suspended one or more resonant members. The clip can be
adapted to fit around the foot of the rail. It can include one or more
tongues extending alongside the web of the rail. This will assist in
separating the damper from the web while still allowing vibrations to be
conducted from one to the other. The tongues can be any suitable height,
for example the full height of the web, or the full height of the
dampers, or less than one or other such heights. Additionally, a damper
for a rail is disclosed, which includes an elongate hollow rigid section
enclosing a deformable material in which is suspended at least two
resonant members, the resonant members being sized to exhibit a resonant
frequency in the range of vibration frequencies of the rail.
