15-Oct-12

Because of potential problems with the TRH's dropping out with corrosion/moisture, I'm taking the wagon-wheels apart, cleaning and coating the back side of the connectors with nail polish and greasing around the 'pin-well'.   This means intermittent outages.   Results, summary below.

16-Oct-12 update: all except 'c' 2.5m and 'm' 15m have been done.   In addition all those done on 15th need to be finished with grease on top of the nail polish.   Will update as things proceed......

ToDo: Clean/Coat Upper at 'c','m',1-8,      Add 3rd screw 2m on ap14,    Grease fill all connector wells.
