I need to find out to which standards south african rail equipment is manufactured.

In the united states, rail equipment is manufactured to the standards
set by the Association of American Railroads.  For example, axles are
manufactured to the standard as set forth if the publication M-101. 
It stipulates the type of steel to be used, tolerances allowed, amount
of pressure to be used to apply a wheel to the axle, etc.

That is what I am looking for in south africa.  Each component has
it's own standard.  The AAR standards take up a bookshelf 5 feet long.

I am not looking for ISO 90001 or 90002 standards.  Those are too general.

Here is a recap of my research to date:

   BS is a british standard
   JIS is a japanese standard
   UIC is the international union of railroads standard (french)
   SABS is the South African Bureau of Standards
   SANS is South African National standard
   GM/RT is a rail trac standard (british)
   AAR is the association of american railroads

The south african rail systen might use any of these standards, but I do not know.

I would prefer to be able to pull the standard off the web for free,
but that is not required.

My ultimate goal is to see if american manufactured rail equipment can
be exported to south africa unchanged

My guess is that they use the British Standards.

Apart from standards issues, the main problem is certainly that U.S.
manufactured engines and wagons are usually made for 1435 mm standard
gauge, while most of the South African railway network is in 1067 mm
narrow gauge. And narrow gauge rolling stock does not simply have
different bogies and more narrow axles - the entire loading gauge is
different from standard gauge railways, engines and wagons are less
wide and high. All rolling stock is designed especially for use in a
narrow gauge system.

I know that the SA railways are narrow gauge and the wagons and
locomotives are narrower and shorter.  Therefore things like axles and
brake beams are not compatable.  But what about wheels or brake blocks
or side bearings or roller bearings?  These things are not as
dependant on the gauge.

Somewhere at Spoornet and/or Transwerk someone has a bookshelf with
the EXACT standard.  If I can find out the name or the document
number, I can then buy it or download or in some other way acquire it.

Have I priced this question too low?

Thanks for your comments.

wuold this information be in 
JANES WORLD RAILWAYS

http://www.abebooks.co.uk/servlet/SearchResults?bx=off&ds=30&bi=0&y=11&tn=JANES+WORLD+RAILWAYS&sortby=1&x=43

The information I am looking for might be in Janes.  There are only 4
pages devoted to South Africa (I looked at the TOC at Amazon), so it
would be general.

I will have to find this book at a library since it costs 745 US$!
