Different embodiments of multiple branch systems in which each branch includes multiple stations, a carrier reversing tube closed at one end, and a diverter having separate ports individually connected to (a) a branch tube which facilitates carrier transfer to and from the branch, (b) station tubes respectively associated with the different stations of the branch, and (c) the carrier reversing tube. The branch diverters selectively complete carrier-conveying paths between (a) the stations of their respective branches or their respective branch tubes and (b) their respective carrier reversing tube. Each branch has a single air supply connected to its carrier reversing tube to alternatively and selectively transfer carriers between stations of the branch via the station tubes, diverter and carrier reversing section, as well as transfer carriers to and from the branch via the branch tube. The multi-branch system, in one form, includes a further diverter and associated carrier reversing tube which selectively interconnects a pair of branch tubes respectively associated with a carrier sending and a carrier receiving branch. Inter-branch transfer is effected by utilizing the air supply of the sending branch in the pressure mode to push the carrier into the carrier reversing tube of the inter-branch transfer network via the sending branch tube and network diverter, and utilizing the air supply of the receiving branch in its vacuum mode to pull the carrier from the network carrier reversing tube to the receiving station via the network diverter and receiving branch tube.
