taking up the oldancient discussion from here:

I changed the string to 'copy backward' as this fits into the button. Any opinions? 'Replicate backwards' is way too long.
If it's too long, I want to suggest Mirror stops
And the tooltip for the button could be Adds the same stops but in reverse direction or something like this.
By the way, there were plans to enable this function to be used also for railways with double tracks. Or was it St-Exp?
