Friction Shoe / Retarder
Sliding friction shoe, also known as retarder, is designed to dissipate the impact energy in a controlled manner. Energy gets absorbed via sliding action of these friction shoes fitted between the buffer stop frame and rail profile. Typically used on metro lines, however this is ideal firction shoe for railway workshops and metro depot track buffer-stops. By virtue of compactness it is compatible with many makes of bufferstop.

It uses a non-destructive friction clamping that is simple in design and provides fairly high breaking force. It is a zero maintenance, fix and forget type equipment. This friction show is very easy to install and uninstall hence presents ease in event of location change. Friction shoe is equipped with a special friction lining material for long functional period.
