if you said the track connected to the switch, there are 3 choices. the diverging track make sense for the one case. possibly the common track in the other case. but i can't think of a good description for the third, the other end of the normal route.Greg I'm not exactly sure what parts of the switch you're asking about or if it's just the routes, as Dave described. Most modelers refer to "straight" and "diverging" routes for the tracks that conect to a switch. A wye is usually referred to as "legs", as in a north leg and south leg.
