Regional programs have been implemented where numerous renting locations are set up at railway stations and at local businesses (usually restaurants, museums and hotels) creating a network of locations where bicycles can be borrowed from and returned (e.g. ZweiRad FreiRad with at times 50 locations). In this kind of network for example a railway station master can allocate a bicycle to a user that then returns it at a different location, for example a hotel. Some such systems require paying a fee, and some do not. Usually the user will be registered or a deposit will be left by the renting facility. The EnCicla Bike Share System in Medellín on its inception in 2011 had 6 staffed locations. It later grew to 32 automatic and 19 staffed stations making it a hybrid between a zero generation and third generation system.
