different model joining

I don't know anything but the revolution, until recently when I get the series before. But I'm noticing the older track is so simplistic at joining and creating your own unique track where as the new revolution stuff is harder to alter I mean we have 3 different sets and parts are so individual making 1 LARGE track isn't an option usually the 3 individuals get joined by there Y pieces and that's it. very tiresome... plarail looks like a good substitute except for then having wasted $$ on the revolutions . things u do for your kids lol
