Hi.

I am looking to create a new layout as per the attached image; the red dots indicate proposed power connection points. The longest length is 4m x 1.1m. I am using Marklin C track, with a Z21 controller and iTrain, with occupancy detection.

I know that usually it is suggested that a track power bus is installed around the layout and then drop wires are used from the track to this bus.

However, I was wondering if there were any operational reasons why the wires from the track connections cannot be run back to the front of the layout and then connected using a strip connector? I appreciate that I will use more wire and I will probably need to increase the gauge of the wire itself.

Very many thanks

Dear Alex - parasitic capacitance can be aproblem, depending on how you do occupancy detection. See, e.g. this discussion for current detection.

Hi thanks for those post. I will be using the YaMoRC YD6016LN -CS current sensing for occupancy detection

Do you have a specific reason for using current sensing instead of ground sensing, which probably >99 % of all C track users, are using?

Yep - I find them easier to set up, and they suit my needs. BigGrin BigGrin
