Mainly, they are the X-Junction, T-Junction and Longer Straight Track. These were designed based on a suggestion to allow for a loop configuration to be deployed:Here's what a small loop configuration would look like:Here's how they look connected to Omega Supreme, at least in this configuration they look "complete" without any portion of the track "chopped off":Additionally, one more part of the "End Cap" is provided to terminate the track and provide some 5mm ports for weaponry to be added in a turret modePew pew pew...Sprinkling in some bots and extra siege effects:Couldn't build a large diorama with these tracks as the photo area was a tad constrained, but the sky's the limit in terms of all the configurations possible! So going to be printing a whole ton more of these and then connecting all the Titans and other figures soon!
