All trolleys work electrically and control wise. One encoder was found non functioning on the upper resonator trolley for the vertical drive it was replaced, we've no move replacements of those current type of encoders so a wholesale replacement of all the trolley's encoders will have to be done post shutdown. Also the wiring for the outrigger is in need of replacement but will work for this shutdown it will also have to be replaced post shutdown as well. The upper resonator trolley has also been setup to remove X2C.
