Sorry I can't remember your plans for this - is it simple analogue control or digital control?
I think it depends on how you want to operate the layout and the sort of switches you intend to use. Again I really must update my Holywell Town thread as I've been sorting out the electrics as well but it's difficult to show any progress. All I can do is show what I have decided on. My intention was to use the MERG CBus system to operate the servo point motors. So I have little pcb mounted switches and LEDs, as the pcb is on a fixed pitched it was simple to draw this out in CAD and laser cut an MDF template of the layout.

I wanted portability and with the CBus system I've used the standard ethernet connectors. So I've squeezed it all into an aluminium instrument box and I used the MDF panel as a drilling template for the aluminium box. I'll then using lining tape/lining pen or printed label to sketch out the layout plan.

Just one option to consider - if you have a plan sketched out then I can cut it out in MDF for you - as long as it doesn't exceed A3 in size!
Many thanks Adrian, that's a very kind offer. As soon as I know what I'm doing and the switching plans are finalised, I may well be in touch.
How is the layout being worked? It's being wired as a two controller, DC cab control with 12 sections. The complication is that there's a master switch that kills the DC input and replaces it with DCC from an NEC controller.
Why both? Well, when building locos they aren't generally fitted with chips until all the bugs and shorts are ironed out. Also I would like the layout to be welcoming to visitors of both the DC and DCC variety.
Turnouts are going to be operated by Tortoise point motors on conventional DC using on-on switches.
The 12 sections switched via on-off-on switches.
There's probably about another 6 switches for signals and ground signals.
I'm going to use Dingham couplings operated by electromagnets. These will be wired back to a rotary switch to select the magnet and a push button to fire the juice.
I'm thinking at the moment of splitting the panel into 2 horizontal sections.
The top strip will have a mimic panel which also has the section switches plus LEDs to show which section is on which DC controller. The diagram will also label up the magnet, turnout and signal references.
Below, on the lower strip will be a strip of switches for the turnouts and signals mimicking a signal box lever frame.
Below is an earlier sketch up of the idea. The turnout numbering etc is wrong as I missed that there are two further crossings that only need a switch each not two.
The small grey circles in the mimic diagram are the section switch locations. Letters A-K the magnet positions. Numbers 2-19 the turnout and signal refs.
I do have another version with the corrected numbering, an extra FPL and few other tweaks but that's saved on the laptop not the phone.
