HELIX BUILD: Block Detection – Episode 9

Follow along as I continue the build of my N scale model railroad. In this episode I complete the helix build by showing you the hardware I use for the block detection of my helix and give you a demonstration of the block detection in use. Be sure to subscribe to my YouTube channel to follow my layout building progress. Also please follow my Facebook page, https://www.facebook.com/chicagosubnscale as I will be adding photos and updates to that as I build my new layout.
