They don't fit in between the tracks! I bought a handful of them trying to keep costs down in my yard and mainline crossovers for now and i am having trouble getting them in place. Model # 206s for n scale. I cut off the second pin and the throwbar that holds the second pin, as well as the throwbar on the opposite side with the hole in it. Trimmed a tie on the neighboring track and still dont have enough room. The tracks are separated only by the width that isbcreated by 2 opposing Atlas #6 turnouts. Really, just frustrated and need to vent. Probably will get some electrically activated undermount switch machines for this purpose, and move the manual throws to the areas where i have more real estate. I had planned to do the whole layout in ground throws for now to save some $$$, but atbleast i didnt buy enough to take care of the entire track plan at once.
