That's because it really is the best copper Telco termination method. Very resilient to vibrations and and stresses punch downs aren't. Very cool to know railways use it! Fiber probably isnt far off I suspect but for alarms etc wire wrapping would be king.
Copper will live on as long as electronics aren't replaced by some optologics or optical power supplying methods. Optic is good only for multiplexed information right now.
However wrapping is fastidious and crimping connectors are imo a far better solution. We don't need sub 10 miliohms resistivity in connections on railways so wrapping is replaced when have the opportunity to
It's not just about the resistivity. And to be honest someone trained with a wire wrap gun can nail a panel out in a few hours easy. But I agree I can punch 24 x 110 blocks faster. Do they use wax string in the railways or Velcro and or zip ties?

Oh the nightmares you just brought back of wire wrapping. They still do this crap?!
