The Prague pneumatic post is an underground system of metal tubes under the wider centre of Prague, totalling about 55 kilometres (34 mi) in length. Known as the Old Lady of Czech telecommunications, the system started service in 1889 and remained in use by the government, banks and the media until it was rendered inoperative by the August 2002 European floods.[2] The current owner, Telefónica O2 Czech Republic gradually is repairing and conserving the system; due to limited funding the system remained inoperative as of March 2007.
The Prague pneumatic post network consists of five main lanes arranged in a star topology. All the lanes converge to the main post office in Jindrišská st. Here all the packages were carefully recorded and from here the network was controlled and monitored.
The lanes consist of steel pipes of 65 mm bore and wall thickness of 2.5–3 mm. The system uses aluminium capsules measuring 48 mm in outer-diameter and 200 mm in length. Each lane is equipped with a dedicated propulsion unit, consisting of an electrically-powered air pump.
