Talk:SA3 coupler

message: 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)
replies: text: Who wrote this nonsense about 6000 ton? Is this some US POV in an attempt to show off? There is a dully recorded run with 43,407 tonnes which requires a lot of prejudice to ignore.37.228.207.64 (talk) 22:26, 10 January 2015 (UTC)
thread_title:  Only 6000 ton? 

message: Since Soviet railways seem to be happy to run trains of "only" 6,000 tonnes and say 800m in length, the absolute maximum capability of the SA3 coupling has never been determined.  However, the heaviest trains  of 30,000T and longest trains of 2,500m use the AAR couplings.    Tabletop (talk) 02:51, 3 August 2008 (UTC)
replies: text: In a test run conducted in September 2011 single GT1-001 freight GTEL pulled 170 freight cars weighing 16,000 metric tons. I guess, capabilities of SA-3 are out of question now.

thread_title:  Heaviest trains 

message: According to coupling (railway) by country, Iraq uses SA3 couplers.  However since the preferred coupling for the UAR in Africa and perhaps the middle east as well is the AAR, perhaps Iraq will eventually convert to this as well for the sake of standardisation.    Tabletop (talk) 02:57, 3 August 2008 (UTC)
replies: text: Iraq is not likely to change because Turkey uses SA3 couplers as well. See Turkey. Peter Horn User talk 21:48, 20 March 2010 (UTC)

thread_title:  Translation needed 

message: This article contradicts Ofoten Line#History, Iore#History, and Iron Ore Line#Heavier trains.
All three articles claim that SA3 couplers are no longer used, and Janney/AAR are used instead since about 2004.

replies: text: The where plans to change over to Janney/AAR-couplers with acquisition of IORE locomotives and gondola wagons from Transwerk of South Africa. However, the wagons didn't fare well in the winter climate. Further orders of the South African wagons where thus cancelled. When the purportedly well-tested and comparably cheap off-the-shelf purchase fell trough, there where no further benefits of using AAR-couplers and the the change-over was aborted. There is some debate on wither AAR are as good as SA3 in Swedish railfan forums, but some say AAR have a higher failure rate in cold weather. The current wagons from K industries are equipped with Willison/SA3 from ASF. The first batch of IORE locmotives that where equiped with AAR have had their couplers changes to SA3.

message: Patent US1194109 A and Patent US1194110 A show Janney coupler compatibles. Just click on the links and look at the patent illustrations. Peter Horn User talk 14:28, 18 August 2017 (UTC)
replies: text: Patent 643581 A also shows a variant of the knuckle coupler. Peter Horn User talk 14:46, 18 August 2017 (UTC)
replies: text: Patent 1601514 A is a firearms patent by someone else. So let us find the REAL patents by, perhaps, the real  Mr. Willison? Peter Horn User talk 15:04, 18 August 2017 (UTC)

replies: text:  Peter Horn, are you saying there is a problem with the google patents record?  or is there a problem with the USPTO records?  or something else? Frietjes (talk) 20:27, 22 August 2017 (UTC)

text: Simply the wrong patents were selected, there must be others. Patent 1601514 A is a firearms patent by someone other than Mr. Willison and therefore irrelevant. Other than that click on the patent lnks and then look at the patent illustrations. WHAT YOU'LL SEE IS A KNUCKLE COUPLER CONTOUR, NOT A WILLISON CONTOUR.

replies: text: Eureka! This is it US1201667 . I'll look for others, if there are any. Peter Horn User talk 23:28, 22 August 2017 (UTC)
replies: text: Then there is this nifty adapter arrangement US4102459. Patent US1194109 A, Patent US1194110 A and Patent 643581 A show special Janney couplers that allow the adoption arrangement to work. Peter Horn User talk 23:45, 22 August 2017 (UTC)

text: Correction, the adaptor dates from 1978 and was not invented by Willison. The three Janney couplers are merely improvements. Peter Horn User talk 00:00, 23 August 2017 (UTC)
