Pipe Maze. Such travel may involve a Traveling-Pipe Bulge. Please note that this does not include using The London Underground (colloquially referred to as "the Tube") to travel.
- The Boom Tubes in The New Gods offer teleportation-like speeds - interstellar distances in a couple of minutes - but take the shape of, well, tubes.
- In E. E. “Doc” Smith's Skylark Series, the largely-aquatic humanoids of Dasor use systems of pipes filled with rushing water as their mass transit system.
- Jules Verne's Paris in the Twentieth Century describes submerged tubes which carry groups of people across the Atlantic.
- Verne and his son Michel Verne would later write The Day of an American Journalist in 2889, which also describes trans-Atlantic tubes, and mentions them as going faster than "aero-trains".
- In Albert Robida's The Twentieth Century, pneumatic tubes are ubiquitous throughout the society of the 1950s. Tubes have replaced railways, the mail service, and even supermarkets - goods are distributed directly to your home, and companies compete on different prices for "on-tap" food, much like power and water.
- In Edward Bellamy's Looking Backwards, tubes are the primary method of transferring goods worldwide in the year 2000.
- In Doc Savage, Savage's skyscraper is linked directly to his hanger on the Hudson river by a tube transport system nicknamed the "Flea Run".
- In Fantasy Island, visitors are sent from a travel agency to Mr. Roarke in a tube travel system.
- In BIONICLE, there's the chute system of Metru Nui.
- City Hall by Tenacious D has this as one of the decrees of the "Two Kings":
The second decree: no more pollution, no more car exhaust,
or ocean dumpage. From now on, we will travel in tubes!
Get the scientists working on the tube technology, immediately.
(Tube technology.) Chop, chop, let's go!
- The most prominent feature in Bally's Xenon is a transparent tube that moves pinballs across the playfield.
- The Jazz Jackrabbit series has these, most famously in the Tubelectric stages.
- The warp pipes in the Super Mario Bros. series are iconic. However, in some cases (such as the warp zones) you appear to be teleporting instead of traveling a path. The latter was never clearly shown in the games until Super Mario Bros. 3, where some levels scroll up or down while Mario is inside the pipe.
- Super Mario 3D World actually lets you control this in the Clear Pipe segments by letting you choose your path, usually to dodge enemies.
- A Link to the Past has this in the Turtle Rock dungeon.
- Clyde's Revenge has this starting with the eighth level. It is possible to go through the tubes in both directions.
- A frequent method of travel in Strider for the NES.
- In Shin Megami Tensei III: Nocturne, this is how you advance in the Bonus Dungeon complete with a Nifty Mini-Game
- In the game Alpha Centauri, the technological advance of Monopole Magnets grants tube travel to your faction.
- Happens in Kirby's Epic Yarn, where Kirby unravels into a single, long piece of yarn and travels through tight spaces in a few levels. You can control moving forward and backwards, as well as move left or right when the path branches off.
- Drill Dozer has many threaded tunnels that require drilling one way or the other to enter and navigate. Defeating the boss of Area 5 involved being able to navigate tunnels within a time limit.
- Very common in the Sonic the Hedgehog games. Sonic the Hedgehog 2 has it in the Chemical Plant and Metropolis Zones, Crazy Gadget in the second Sonic Adventure game, Secret Base and Egg Rocket in Sonic Advance, and others.
- Cave Story has one, though it isn't important to the overall gameplay. It just there to help you get out of Plantation's water reservoir faster (possibly in case you fall in without the jetpack equipped).
- Earthworm Jim 2 had this in the ISO 9000 level, though it looked painful (the entrance was a grinder).
- Happens briefly at one point in Portal.
- Is built up on more in Portal 2. Tube travel is the main way everything in Aperture Science gets into test chambers, it is ridiculously inefficient and expensive, and there are so many props in the facility that no one even cares.
- Mr Gimmick has these.
- Command & Conquer: Generals features the Tunnel Network for the GLA, which involves building separate entrances that are somehow magically connected the instant the Tunnel entrance is completed no matter the distance or location on the map.
- StarCraft: The Zerg have the Nidus Canals, which act in the same way as the Tunnel Network as mentioned above.
- Sackbots are transported this way in LittleBigPlanet 2.
- Cosmos Cosmic Adventure has these, though it's a bit odd since the pipes look too thin for Cosmo to fit.
- F-Zero X and GX have levels where you are in a tube, and on the outside of a tube.
- In X-COM: Apocalypse, the People Tubes of Mega-Primus are the primary form of pedestrian travel. They happen to be quite fragile when the lasers start flying. The Tubes are owned by the Trastellar corporation, and pissing them off can cripple your ability to move personnel.
- Ecco The Dolphin loves this, particularly in the later levels when Ecco is nearing the Final Boss.
- Mass Effect 2 has one of your squadmates do this during The Very Definitely Final Dungeon.
- Tinhead has tubes to travel through in many levels.
- The Crazy Castle games have small pipes which the player character can travel up and down through, with a bulge.
- The Suction Tubes in Bounty Bob Strikes Back.
- The Eldar in Dawn of War can move between Webway Gates; up to ten infantry units can occupy the Webway at any time. The Imperial Guard can do the same with most of their structures, although only one or three units at a time.
- The BBC Micro game Pipeline had this as the way to cross the Pipe Mazes, though you had no control while passing through the pipes.
- The Rainbow Arts game Rock 'n' Roll has tubes for the player's ball to travel through.
- Metal Morph has tubes in the platforming stages. You have to turn into liquid to pass through them.
- The Terminator for the Sega CD has a few fast-travel suction tubes, though they only go straight up and down.
- Starship Titanic had the Succ-U-Bus, which allows travel across the titular ship.
- This is how John Freeman gets into GLaDOS's chamber in Djy1911's adaptation of Half-Life: Full Life Consequences.
- Futurama has the Tube Transport System.
- Spoofed in "Rocket Squad", a Looney Tunes parody of Dragnet set in space, where the pneunatic tube system provides a bumpy ride for Daffy and Porky, with the latter remarking how people used to use elevators.
- The Jetsons featured tube travel that sucked you up and plopped you where you wanted to go, as part of its Retraux aesthetic.
- Some playground and water slides are like this.
- Some hamster cages are set up like this, being a series of smaller cages linked by tubes.
- Pneumatic Tube systems (AKA "the things in bank drive throughs", though some larger people movers have been made). Likely an inspiration for at least some of the above examples.
