A pneumatic delivery system capable of transporting an information container around a sharp bend or corner without the need for conduit disposed on a large radius of curvature. A pneumatically movable capsule is positioned in a first conduit to carry the information container to the bend or corner where it leaves the capsule and enters a second conduit. Additionally a transfer station and an intermediate station are present which include a pneumatically movable capsule for transferring an information container from one deliver conduit to another and for withdrawing an information container from a delivery conduit respectively. Another aspect of the disclosure is a rotatable capsule positioned at the junction of two delivery conduits which receives an information container traveling in one conduit and is pneumatically rotated to a point where the information container can leave the capsule and travel through the second conduit.
