The R8206 Power Track is a complete track piece with an integrated wire connector that is based upon sprung loaded terminals. The connector parts of the R8206 do not remove to be able to be fitted somewhere else. The product is one single integral piece.
Note the buff press buttons. Pressing these buttons releases spring pressure inside the connector that allows 'bared' wires [if thick enough] to be clamped inside the connector.
The R602 track clip can be located in certain positions in any current Hornby straight of curved piece of track (not points). The positions are indicated by gaps in the plastic webbing between the webbing and the underside of the rails. If you hold a current Hornby track piece level with your eyes and look at the track side on, you will see these little gaps spaced along the length of the rail. There is usually also an arrow embossed into the underside of the rail plastic webbing that also shows the position reserved for the R602 clips.
This connector does require the wires [if using bare wires] to be fixed in the holes with some form of peg arrangement as WTD describes. These pegs would normally be the manufactured terminals that are included on the end of current Hornby controller attachement wires.
Instead of a fixing peg [made of your own design and implementation] you can use the X8011 terminals I mentioned earlier.
The X8011 terminals can also be used in the R8206 wire receptacles as well.
