Heritage Mechanical Codes & Guides

(Recent additions and amendments are shown in red.)

This page contains the mechanical codes, drawings, guides and manuals approved by the Joint Technical Committee - Heritage Technical (HTC).
They define suitable minmum mechanical standards and practices for Heritage Network Operators (HNO) operating on the National Rail System (NRS).
HNO's may use these codes as they stand or as a guideline to developing their own codes and guides.
Other heritage rail operators are welcome to make use of these documents but may wish to relax some standards taking into account lower operating speeds, train sizes and weights.

The Federation of Rail Organisations of NZ, Inc and the New Zealand Railways Corporation will not be responsible for any unapproved or unauthorised use of these documents,
 
These codes and guides are subsidiary to the requirements of the National Rail System Standards, in particular NRSS 6 - Engineering Standards and NRSS 11 - Heritage Train Management.
See B3.1.1.01 - Mechanical Code; Section 1.6 for an explaination of the hierarchy of these codes.
