Move trains from one track to another with this Rail Cube Junction Kit! Each junction piece splits one rail into two with the switch of a button. This is a fun way to either make a single rail more complicated, or to join two completely separate tracks together. I could see the joining of tracks being a great option for those with multiple kids that would want to join their sets together for even more fun and sharing. My siblings and I would have absolutely loved these sets as kids! Includes two junction pieces only. Track pieces sold separately.
