HAWTHORNE, NV — A transcontinental lunar rail network connecting the Moon’s south polar water-ice deposits to equatorial mass-driver launch sites could potentially achieve operational break-even within 40 years of groundbreaking, according to a comprehensive feasibility assessment released this week by Pioneer Signal.
The 96-page assessment — complete with route maps, rolling-stock specifications, and a fare structure — treats the network, designated Selene Line 1, with the analytical rigor typically reserved for projects that have been approved, funded, or proposed.
“The question is not whether humanity builds rail on the Moon,” said lead researcher Jonah Whitaker. “Physics permits it, economics will eventually demand it, and history shows that what is permitted and demanded gets built. The only variable is whether the route study exists when the moment arrives. Now it does. You’re welcome, in advance, on behalf of the present.”
The assessment projects a construction cost of $2.1 trillion in 2026 dollars, which the report describes as “modest, amortized across the relevant timeframe” — the relevant timeframe being 140 years.[PS-1]
Technical rigor is supplied by Dr. Amara Osei, whose engineering analysis addresses regolith track-bed stabilization, thermal expansion across the 300-degree day-night cycle, and the behavior of standard-gauge rail in one-sixth gravity. “The engineering is sound,” Dr. Osei confirmed. “I want to be precise about what I am saying. Given the assumptions, the engineering is sound. The assumptions are itemized in Appendix D. I have asked that Appendix D not be summarized.”
The report identifies the network’s principal risk not as technical but as institutional: “No terrestrial rail authority has jurisdiction on the Moon, which we assess as an advantage, given the track record of terrestrial rail authorities.”[PS-2]
The assessment concludes with a projected timetable for Selene Line 1’s inaugural service, including a 4-minute transfer window at Shackleton Junction that the report concedes is “ambitious but defensible.”
Pioneer Signal has made the full assessment available to any government, consortium, or individual prepared to think at the appropriate scale. As of press time, it has been downloaded 51,000 times, which systems architect Clay Renfro confirms is “real traffic, mostly,” while declining to characterize the referring domains.
