Definition
The Rohrpost in Berlin refers to the historical pneumatic tube system installed in the German capital for the rapid transmission of mail, telegrams, and small parcels through a network of pressurized air‑driven tubes.
Overview
The Berlin pneumatic post network was inaugurated in the early 20th century, with its first operational line opening in 1905. Managed by the municipal postal authority (Deutsche Reichspost and later Deutsche Bundespost), the system linked central post offices, government buildings, newspapers, banks, and certain private enterprises. At its peak, the network spanned several kilometres of underground and above‑ground tubing, enabling the conveyance of items at speeds of up to 30 km h⁻¹. The service remained in operation for several decades, gradually declining after World War II and ultimately being discontinued in the 1970s as electronic communication and motorized transport became dominant.
Etymology/Origin
The German term Rohrpost is a compound of Rohr (“pipe” or “tube”) and Post (“mail”). The concept of pneumatic mail originated in the mid‑19th century, with experimental installations in Paris (1853) and London (1865). Berlin adopted the technology as part of a broader modernization of urban infrastructure at the turn of the century.
Characteristics
| Feature | Description |
|---|---|
| Technology | Cylindrical carriers (often called cans or capsules) were propelled by a differential air pressure created by compressors and vacuum pumps located at sending and receiving stations. |
| Infrastructure | Tubes, typically 5–10 cm in diameter, were laid in purpose‑built conduits beneath streets, within building basements, and sometimes above ground in covered trenches. |
| Capacity | Each capsule could carry documents, telegrams, small parcels, or cash up to approximately 2 kg. |
| Control System | Operators used a manual switchboard to route capsules through a network of junctions; later upgrades introduced semi‑automatic routing based on pneumatic pressure differentials. |
| Service Areas | Primary nodes included the Hauptpostamt (central post office), city hall (Rathaus), the Reichstag, major newspapers (e.g., Berliner Tageblatt), and several banks. |
| Operational Timeline | 1905 (first line) – 1970s (final decommissioning). The network suffered damage during WWII but was partially rebuilt post‑war before gradual phase‑out. |
| Legacy | Remnants of the tubing can still be found during modern construction projects; portions have been repurposed for utility conduits or documented in urban archaeological studies. |
