47kg Standard Rail, Supplied Across Australia

Inform Rail supplies 47kg standard rail for like-for-like replacement on existing 47kg track across Australia, through Brisbane and Cairns distribution. The 47kg is the metric equivalent of the imperial 94 lb/yard rail section and is classified as a legacy profile, absent from the current AS1085.1-2002 standard. The profile is sometimes written 47 kg rail, 47kg/m rail or specified by its imperial designation, 94 lb rail.

The 47kg remains in service 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 section. For new construction or major rehabilitation, network owners typically specify an active profile such as 50kg or 60kg instead. For full background on this profile, read our article 47kg and 53kg Rail in Australia, From Imperial Roots to Modern Networks.

Rail is supplied in a standard length of 12 metres, with cut-to-length and drilling to your bolt pattern available prior to dispatch. 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, and the profile is sometimes written 47 kg rail, 47kg/m rail or 94 lb rail.
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 CL4-16, 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.
