They've got approval to build a 90 mile rail line south to a year round anchorage, but haven't pulled the trigger for a number of reasons. I believe this would be the northern most railway in the world if it ever gets done.
SA-3 (modified Willison) is used because it tolerates 'snow pack' better.
This design is used in Mauritania on up to 21,000t trains.
CMStPnPInteresting video, looks almost like an American operation. Check out the funky couplers, guessing the coupler design works better in extreme cold. https://www.youtube.com/watch?v=BfUxVONfHOY&t=14s

Forget where I read it, but, those Soviet style couplers do not have a draft capacity anywhere near what the US style knuckle couplers have. Thus their trains are restricted to 6800 tons.
While the line is designed for heavy axle loadings, it is not designed for lenghty US style trains.
Never too old to have a happy childhood!
