Techniques for management of movable devices are disclosed. A system receives a request for an operation associated with a position on a rail. The system selects a component on the rail to execute the operation. The system identifies a rail segment that extends from the component's initial position to the position associated with the operation. The system requests a reservation of that rail segment. If the reservation is obtained, then the system applies electrical signals to move the component along the rails segment to the rail position associated with the operation. The system may also identify one or more other components, physical cells, etc. to reserve, in order to complete the operation.
