Remote control systems on modern ships usually have a control transfer system allowing control to be transferred between locations. Remote control is usually possible from two locations: the bridge and the Engine Control Room (ECR). Some ships lack a remote control handle in the ECR. When in bridge control mode, the bridge handle directly controls the engine set point. When in Engine Control Room mode the bridge handle sends a telegraph signal to the ECR and the ECR handle controls the set point of the control system. In local control, the remote control system is inactive and the bridge handle sends a telegraph signal to the local control position and the engine is operated by its manual controls in the engine room.
