The much-older [[vactrain]] concept resembles a [[high-speed rail]] system without substantial [[Drag (physics)|air resistance]] by employing [[maglev|magnetically levitating]] trains in [[vacuum|evacuated]] (airless) or partly evacuated tubes;. howeverHowever, the difficulty of maintaining a vacuum over large distances has prevented this type of system from ever being built. SimilarlyBy contrast, the Hyperloop alpha concept was to operate at approximately {{convert|1|mbar|Pa|spell=in|lk=on}} (roughly one thousandth of an atmosphere) of pressure, butand would require compression ofrequires the tiny amount of remaining air for levitation.<ref name="nova20130813"/>

* [[Swissmetro]] was a proposal to run a maglev train in a low-pressure environment. Concessions were granted to Swissmetro in the early 2000s to connect the Swiss cities of St. Gallen, Zurich, Basel, and Geneva. Studies of commercial feasibility reached differing conclusions and the vactrain was never built.<ref name="swissmetro"/>
* [[ET3 Global Alliance]] (ET3) was founded by Daryl Oster in 1997 with the goal of establishing a global transportation system using passenger capsules in frictionless [[magnetic levitation|maglev]] full-vacuum tubes. Oster received interest from Elon Musk potentially investing in a {{convert|3|mi|km|0|adj=on}} prototype of ET3's proposed design.<ref name="denver20130809"/><ref name="futurist20131030"/>{{update after|2015|6|17}}

However development stopped after funding ceased.<ref>{{cite web |title=The Hyperloop that never was |date=5 May 2021 |url=https://sifted.eu/articles/italy-deeptech-pipenet/ |publisher=Sifted |access-date=2021-08-26 |archive-url=https://web.archive.org/web/20210505172003/https://sifted.eu/articles/italy-deeptech-pipenet/ |archive-date=2021-05-05}}</ref>
* In August 2010, a vacuum-based maglev train able to move at {{convert|1000|km/h|mph|abbr=on|order=flip|round=50}} was proposed for China, projected to cost {{CNY|10–20 million|link=yes}} ({{US$|2.95 million}} at the August 2010 exchange rate) more per kilometer than regular high-speed rail.<ref name="engadgetsumohurd20100804"/> In 2018, a short {{convert|45|m|yd|abbr=on}} loop test track was completed to test some parts of the technology.<ref>{{cite news |title=China testing super-maglev train that runs at 1,000 km/h |url=http://en.people.cn/n3/2018/0311/c90000-9435653.html |access-date=2021-08-26 |publisher=People's Daily Online |date=11 March 2018 |archive-date=24 October 2021 |archive-url=https://web.archive.org/web/20211024003226/http://en.people.cn/n3/2018/0311/c90000-9435653.html |url-status=live}}</ref>
