I have been adding my own tracks to the Holiday Express and I'm customizing it to my liking, however I am running into problems with joining tracks and attaching tracks to turntables and or traverses. What am I doing wrong and what bullet buttons should I be using when I'm trying to attach two Rail-End Devices together, and when I do the other end becomes another abutment! RWAR Frusterating!
How do I connect these two Rail-End Devices without creating another Rail End devices on the other end?

Like the picture below, I am having problems connecting the turntable tracks to existing track, what am I doing wrong?

I will appreciate the responses, thanks y'all!
