As I am intending to run all of my stock with standard tension lock couplings the remote uncoupling will be via pads which will be remotely lifted to raise the hooks.

These will be "lifted" by a "see saw" rod based system.

The lifting pad is made of 3mm x 12mm flat copper bar with 3mm diameter brass rod and a track pin. The rod and the pin are soldered into place. The track pin is an anti-rotation device so the pad remains in the correct orientation through out its range of travel.

Each one is stamped with an identifying letter in case multiple need to be removed at one time.

The lifting pads are actuated via control rods from the edge of the layout. The rods are 3mm plastic coated rods which were relieved from an old clothes airer. The rods are connected to the pad push-rod via a yellow electrical ring connector with a 3.2mm hole. A 3mm button head sets crew passes through the eyelet via a crinkle washer and two form A plain washers into the brass portion of a 6 amp electric terminal block. Small compression springs return the pads and control rods to the initial position.
