Safeplug procedure

Where to use drilled rail plugs?

SafePlug®, Rail drilling plug, used for connecting electrical cables and connectors to railway rails ( vignoles rail), and tramway rail, also known as grooved rail and girder rail. The cables might be for signals, power supplies and protective earthing along the railway.

To attach the drill plugs one ??use of a rail drilling machine, and a special rail drill to drill the hole in the rail.

SafePlug® bushings fitted with an impact wrench or a standard torque wrench and an installation tool that expands a tin-plated bushing into the hole. Then assemble the cable lug with the enclosed screw joint.

What does the SafePlug® so special?

Safetrack's drill plugs for rail has been developed since the existing brands in the market are not taken into account the impact of vibrations and the strong temperature differences. These temperature differences lead to that the rail expands and decreases (constrict), substantial in size both during winter to summer, but also between night and day.

The SafePlug® High Torque (HT) is a unique version with even higher torque capbility made of high-strength 10.9 stainless steel for the most demanding areas.

All SafePlugs® has the feature with a constant contact pressure between the bushing and the rail which minimize the risk of  contact fault caused by corrosion.

Such defects must never occur because the drill plugs into rail usually are used for protective earthing along the track. Should these protective earthing fail, it means danger to the track staff and for the public.


Users do not have to use heavy hydraulics in the work place. Expanding

the copper bushing in the drilled hole in the rail by using the same torque wrench or impact wrench used to assemble the cables.

Means significantly lower investment costs as well as smaller service needs.
