What pneumatictubes.info is
Not a theme park.
pneumatictubes.info covers urban pneumatic postal systems, and the hospital/warehouse industry that shares a pressure gradient with them as a separate living industry. It is not a journal, not a vendor, and not a steampunk gift shop.
Coverage is the documented city networks, with photographs already under open licences. Tone is dense, like a well-kept amateur museum.
Citations are on Sources. New York statistics come from Smithsonian / National Postal Museum captions, including the cases where those captions disagree. Hospital pneumatic tubes are a separate living industry. Map posters may appear in the shop later. Replica canisters will not.
Corrections welcome.
Limits
A complete world gazetteer. A speed calculator. A place to buy a “mail rocket.” A conflation of 1897 city post with 2026 hospital PTS.
Licence posture
Prose: use it, quote it, correct it. Images remain under their own licences — see CREDITS.md. The 2025 Austria Post stamp is on the Vienna page and on PostAG; image notes are in CREDITS.
