Saw on a video a coal mine in Pakistan where they use angle-iron for
rails - shows rope-worked decline the wagons come to surface along.
Which I take it is cost-justified?

I've been changing from steel to synthetic winch cable which has better handling properties, mainly no sharp broken ends, also it isn't stiff and springy and stays in place on the winch spool.
Strong rope is available in nylon which stretches a lot and absorbs shocks, and polyester which doesn't. The breaking strengths are similar. In mountaineering they are called Dynamic and Static. For most purposes I prefer braided polyester when I can find it.
This sliding/locking knot and the cord suitable for it are very useful.
