I wonder if this could be done using only regolith. A recent study showed that laser sintering of regolith might be a viable way to pave pathways. The resulting material had a compressive strength in the range of 8k to 30k PSI. Considering the reduced gravity, I could see this being strong enough to use as the rails. https://www.nature.com/articles/s41598-023-42008-1 https://www.nature.com/articles/s41598-023-42008-1
