Abstract
Clips for holding down railway rails are driven into position, for example by driving parallel to the rails, by power-operated apparatus with wheels which run along at least one rail. There may be one or two power-operated devices for driving clips one at a time or two at a time on opposite sides of the same rail or four power-operated devices for driving four clips at a time, one on each side of each rail. The power-operated devices may comprise piston-and-cylinder devices driving levers.
