Neat - thanks for sharing! That’s the powered style track, I think. I have some around here somewhere - nice build 
Yep Jim it is for sure the 9V powered track, the very track that Lego has discontinued, so if you have some and don’t use it, you will be sure to find buyers for it on e-bay!
What is the gauge of this track, is it one compatible to others or is it a unique one? Inquiring minds want to know (me) Thanks for any clarifications offered in advance.
It is its own unique guage sadly.
