Hi,

If you are planning on connecting your M track directly to C track you would need 2 of the M to C track transition tracks 24951. Depending on the size of your layout you might not need to add additional power feeds to the track. However, assuming that you have to add additional power feed wires this time to the C track then you would need the Marklin C track feeder wire set 74040. Normal practice for digital operation is to add a set of power feeder wires approx. every 6 feet of track length.

1. Since I believe the transformer you are using has the push clip connections, I doubt it would be feasible to push in a second set of wires. So what I would do is run a wire from the red terminal to a terminal strip and then connect all the red wires you plan on adding to that terminal strip. Repeat this for the brown wire. In analog if you are only running one track then you would only need one transformer. However, if you plan on isolating your tracks in order to independently run another train then you would need an additional transformer.

For the 74040 wire set, the blade connectors connect to the appropriate spade connectors below the track (red to B and brown to O). To connect the other end to the terminal strip you need a screwdriver or the appropriate plugs depending on what terminal strip you plan on using.

2. The 6021 connects to the track the same way with the red and brown wires. However, you can now run more than one locomotive on the same track without worrying about isolation of separate track circuits. The 80F just plugs directly into the 6021.
