Model Railway Wiring for Block Detection in DCC - part 1

How to wire for block detection in DCC.

I am extending my layout from the storage area up towards the main scenic layer. Two new block sections are being wired in. In part 1, I take you through how I wire for block detection in DCC. Part 2 will cover the computer configuration, and a demonstration of the new sections in action.

Let me know in the comments if you appreciate the voice-over.
