47kg Standard Rail — Legacy Profile

Inform Rail supplies 47kg standard rail for like-for-like replacement on existing 47kg track across Australia. The 47kg profile is the metric equivalent of the imperial 94 lb/yard rail section and is classified as a legacy profile — it does not appear in the current AS1085.1-2002 standard, which lists 41, 50, 60 and 68 kg/m as the active profiles.

The 47kg is commonly used as a like-for-like replacement on portions of the ARTC interstate network and legacy industrial infrastructure where 47kg track is already installed. For new construction or major rehabilitation, network owners typically specify 50kg, 53kg, 60kg or 68kg instead. Where 47kg replacement is required, Inform Rail can supply matched fishplates and fastening systems. For full background on this profile, see our article: 47kg and 53kg Rail in Australia: From Imperial Roots to Modern Networks. Matched fastening systems including clips, fishplates, sole plates and rail pads can be supplied to suit the profile and substructure.

FAQ

47kg Rail: Common Questions

What is 47kg standard rail used for?
47kg standard rail is commonly used for like-for-like replacement on existing 47kg track. It is the metric equivalent of the imperial 94 lb/yard profile and is a legacy section absent from the current AS1085.1-2002 standard. It remains on portions of the ARTC interstate network and legacy industrial infrastructure, where replacing in kind is preferred over the cost and complexity of upgrading to a heavier profile.
What are the dimensions of 47kg rail?
47kg rail has a head width of 70mm, a height of 141.3mm, a foot width of 127mm and a web thickness of 14.3mm. The mass is approximately 46.5 kg per metre.
What is the difference between 47kg and 41kg rail?
The 47kg is slightly heavier than the 41kg and derives from a different lineage — the imperial 94 lb/yard section metricated to 47kg, whereas the 41kg is an active AS1085.1 profile. The 47kg is used mainly for replacement on legacy track. The 41kg suits new industrial applications. For new construction requiring more capacity than 41kg, the 50kg or 53kg are typically specified instead of 47kg. Send us your application details and we'll advise.
What clips are compatible with 47kg rail?
Compatible welded clips for 47kg include the M71 and M120 for steel substructure installations. Compatible bolted clips include the CL4-20, CLX-20 and CLX-24. Clip selection depends on the substructure type, installation method and load requirements. Send us your drawings or application details and we'll advise on the correct clip.
Can 47kg rail be supplied cut to length?
Yes. 47kg rail is supplied in a standard length of 12m and can be cut to your specified lengths prior to dispatch. Drilling to your bolt pattern is also available. Include your cutting and drilling requirements in your enquiry.
Can Inform Rail supply a complete 47kg fastening system?
Yes. We can supply matched 47kg rail clips, fishplates, sole plates, rail pads and hook bolts as a complete package. Send us your rail profile, substructure details and any drawings and we'll quote a complete fastening system. No minimum order applies.
