Abstract
A trolley runs along a railway track and a member on it strikes railway clips and removes them from rail-securing positions. The clips are of a kind having a first portion substantially parallel to the rail and driven into a projection beside the rail, a second portion bearing downwardly on the rail flange and a third portion, further from the rail than the first portion, bearing downwardly on an unyielding surface.
