You can't "Overkill"! Bus wire size depends on....... The size of the layout. The number of locos to be moving including sound fitted ones plus a small amount of current needed for those stationary and with lights on and perhaps sounds on.
Small to medium layouts 1.5mm2 solid is perhaps ok while medium sized layouts need 2.5mm2 though this can equally be used on smaller layouts without problems
If you want flexible wire for the bus then 32/0.2mm or even 50/0.2mm would be ok.
Consider also splitting the layout up into electrical sections (Called zones) with Insulated Rail Joiners (IRJs) on each track entering and leaving the section, Then feed each zone via a sub bus fed from the main bus wires. I would recommend using a electronic circuit breaker (Such as the EB1) to protect the sub bus as this will trip before the main console under a fault in the zone and help to ensure only the problem section stops working while the rest of the layout remains operational. Also ideal to have the layout sections as its aids fault finding too!
You may find the DCC page of this web site helpful? Which details zones and bus feeding etc .. http://www.brian-lambert.co.uk/DCC.htm

Broken? It was working when I left it!
