Jeff, Thanks for sharing your website address. Examined your approach to wiring and find I took a similar approach to wiring turnout controls and signals. Like you, I use Cat5 however, instead of 66 blocks I use a patchpanel with a 110 block in my DCC drawer as I have over 30 detection blocks and the feedback system requires home run wiring. I use a levitron RJ45 socket at the far end plugged onto an RJ45 end of the cable. I then punch wires to the socket (actually a mini 110 block).
For Turnouts, I use Wabbit/Hares that require only connection to the DCC bus. I use a PC operated CTC panel to control all turnouts remotely and local pushbuttons at each turnout location when manual switching is desired.
Glad to see others using network wiring capabilities for their Railroad.
My blog has more information and pictures on the approach I used on the C&SF.
I also intend to use cat5, a punchdown distribution panel, leviton quickports, etc. for wiring… pretty well everything except track buss. If you have the tools and know how it’s a very neat easy to manage wiring system. IMO. [:)]
