0 ga tube track is used for STD. The ties are the difference.
As a test. I used 0 ga 072 with STD 072 rails. Difference. 0 ga rails are shorter.
I find using used ties a pain. Much rather have the 0 ga ties made of plastic or wood. Cause it needs to be insulated. If you want to run independently. As for power just jumper the rails.
