Looks like you did an excellent job on the diagram - I read elsewhere on this site comments about the reliability of the system in later life. Fyffes wee Spanish built container ships had a bridge control system for their two Deutz diesels. Problem was ( similar to that commented on ) was the excess starting air used when bridge controlled. The engines of these ships were a good distance aft of the bridge so no aural indication of a successful start, the only indication was when the rev counter started to rise. I don't know how the ships passed Lloyds inspection as the sole air compressor was not up to the task- not only had the air system to start the engines it had to shift the camshafts and operate shaft brakes. On one of the early voyages entering the berth at Galveston we nearly buried the bow on the opposite pier as we tried to execute a sharp turn. Confidence was lost and direct local control became the order. The M-Class of MAN engined ships had controllable pitch propellers a much better proposition in my opinion.
