Jet-Postal is a postal service of Rapture which uses Pneumo Tubes to deliver mail between locations through pneumatic technology.

Jet-Postal consists of several substations similar in function to post offices which served various areas and businesses such as in Neptune's Bounty's substation number two and a private office catering the needs of the Atlantic Express in their Train Workshop 6B. Those stations contain numerous Pneumo tubes, lockers, an office, and shelves to sort/store the messages or packages. Ryan Industries finished installing and activated the Pneumo system in 1956, on the 10th anniversary of Rapture's founding.[1] The 1958 New Year's Eve Riots and the civil war did not prevent the pneumatic systems from working, although the stations were left deserted.

Letters: a popular way of communication in Rapture.

Pneumo tubes were the primary postal service in Rapture prior to the Civil War, and also delivered packaged food to different parts of the city. Many Pneumo tubes, such as the ones seen in Fort Frolic, were labeled with a serial number system similar to post office box numbering on the surface. This numbering system included letter abbreviations of the location of Rapture in which the tube was located. However, since the Civil War, the Pneumo tubes have become quite unreliable and useful only for short range message transport. This is due to the damage Splicers caused to the pneumatics controlling the air flow, and lack of proper maintenance. Sending a message long range could send it anywhere in Rapture, or have it jammed up in some intermediary tube in the system.

Burial at Sea[]

The pneumatic delivery system of Jet Postal returns in BioShock Infinite's downloadable content, Burial at Sea. It also introduces Pneumo Lines, a new kind of service provided by the company which can deliver larger packages with Pneumo Bots running on lines parallel to the regular pneumo tubes.


Behind the Scenes[]

One of the unused UI screens for the trading system.

  • The Deco Devolution artbook mentions that an early idea for BioShock 2 involved the player trading for supplies with isolated camps of Rapture survivors through the Pneumo tube system. The developers had already created a model and several UI screens for the Pneumo trading machine before it was cut from the game. It was ultimately removed because the survivors idea was no longer a part of the storyline.[2]
  • As shown in Burial at Sea - Episode 1, Jet-Postal uses the Roman god Mercury[3] as an emblem for its speedy pneumatic delivery systems.
