I have decided to use Peco code 75 track on my next layout in the loft. Having purchased my first two points I have noticed that there is a total short between the left and right track at the frog. There is a wire under the track which links up the track to produce a deliberate short. Removing the offending wire would seem to serve no purpose as the rails touch each other at the frog nib anyway. Am I missing something? I have seen an article somewhere about modifying the electrofrog points to accommodate DCC but cannot relocate it.
