[edit] Factual Inaccuracies
Well, actually the 1524mm gauge was chosen because it is exactly 5'0 between the rails. And the SA3 coupler is a development of the Willison type, with the same general idea of a fixed head with internal locks to stop two couplers from coming apart, although (from photographs I have seen) the Willison generally has a much simpler internal mechanism that operates around a vertical axis, whereas the SA2 and later SA3 type couplers have a more complicated locking system that operates around a horizontal axis.
[edit] SA-3 is NOT a Janney Copler
SA-3 coupler is an essentially differs from Janney coupler. These are absolutely different development.
Janney coupler: The traction effort is transferred from one coupler to another coupler through rotary details.
SA-3 coupler: The traction effort is transferred directly from the body of one coupler to the body of another coupler.
P.S. Sorry for my bad English

[edit] Only 6000 ton?
The couplings must hold at least 9000 ton: With a weight up to 8600 ton, and a maximum gradient of 10 permille, the iron ore trains of Malmbanan don't snap. Ssteinberger (talk) 20:48, 18 April 2008 (UTC)
