Frequently their internal wires are very fine, less than 7/0.2mm and this when needed for larger current requirements such as Solenoid point motors and returns is too small, so you then double or treble up their cores to make an overall larger wire size. But of course in doing so you reduce the number of circuits passing through the cable! ;)
One way to get round that problem is to use relays preferably triggered by transistors. The relay/transistor circuit would have to on the baseboard to enable you to have quite thin wires going back to the control panel. There are plenty of multiple relay boards available on eBay and ones with something like a Darlington array to drive them would be quite compact.

Hi Richard,

Now I'm totally out of my depth, and drowning, even the use of a diode bridge is getting to be a bridge too far for me, excuse the pun. I think I'll stick with 25 pin D connectors and mount them on the outside of the table support legs.

If you're going with 25 way D connectors have you seen or considered using these at the fixed end? They make the onward wiring to the layout so much easier! :D
Example (there are others and cheaper from China too!) Link to 25 way breakout connectors

Hi Brian,

Now you're talking my kind of language, no I hadn't seen these types of 'D' connectors. Much easier, being an oldie like myself, soldering up point motors is sometimes a bit of a challenge.
