screw dowel

 

Rail plastic dowel is also called rail plastic sleeve/plastic insert/concrete dowel/ concrete insert, which is a counter-party fastener for a screw spike or anchor bolt, and it is pre-imbedded into the concrete sleeper or wooden sleeper, installed together with screw spikes, guide plates and rail clips to fasten the rail tracks.

rail clip

 

Rail clip, or called elastic rail clip, is used to fasten steel rails to the underlying tie plate. Through bending and distortion, rail clip can put pressure on the rail, which prevents longitudinal movement of the rail, either from changes in temperature or through vibration.
