My point was that I do not believe D21 curves can be used with the Y Tracks. As far as I know, the Y Tracks can only be used with D16 curves. Joe said he needs to use D21 curves for his Western Hobbycraft trolley.

I have used both 21 & 16 inch curves with the Y track, so it is possible to use either curve size but you may need 2.5 inch curve to curve straights between the curves and the Y track for proper spacing.
