Got some questions regarding Peco N scale track: 1) I understand that their Code 55 track is actually Code 80, with the "bottom 25" embedded into the ties. If this is true, it seems to me that connecting their Code 55 to their (or anyone's) Code 80 would simple, since the exposed ends that you would be connecting would be Code 80. Right or wrong? 2) Does this embedded feature make it any harder or different when soldering feeder wires to the rails? 3) I also understand that their turnouts follow the "British design", i.e. the diverging rails are of a constant radius. For example, their "small" turnouts use a 12" radius. Can this be visualized as laying a section of 12" radius curved track onto a straight section? If so, then a) How far from the end of the straight section does the curve start? b) Through how many degrees does the curved section extend? c) Is there a straight section on the diverging end of the curved section? If so, how long?
