Hi Dave
Yes, that's an idea to supply the plate, but its still up to the modeller to get that aligned with his track- could still lead to problems. Just thinking- if there is problems, we remove the dowels on that board?
Here is an interesting diagram for DCC from the Fremo site;- http://fremodcc.sourceforge.net/dcc_e.html and in this area a wealth of electrical stuff for modular building.
