Planting on railroad ballast

I live just downslope from an active railroad track. It was covered by stinging nettle, but I’ve removed most of it over the years. I need something to plant there beside the morning glory and small trumpet vines to cover the gaps. It is a steep sloping grade with solid ballast rock, and I don’t want the nettle taking back over. I have a periwinkle patch elsewhere. Would that possibly work on this area? I need a no-maintenance idea, as the slope is steep. Thank you for your help. PS – full sun. Good drainage. Good soil underneath.

Periwinkle would be best in a part sun location.
Here are some links with some other ground cover choices.
