Question: I find it interesting that part of the final chase is against a modified truck on a set of rails. I saw no rails in the wide shots of Bartertown, and no exits for the the truck. So, where was the exit, why use a modified truck for power when it was never cranked, and how did the kid know to be prepared for the truck, or any rail traffic, at all?
Question: Since this is set years after the "Pocky-clipse" (as called by the kids), while Max and a lot of others have long hair, why do they mostly not show any facial hair? Given there are some knives and razors, but it would seem that shaving wouldn't be high on the list of survival.
Chosen answer: Actually grooming would be somewhat important, if only for general comfort. Unruly facial hair can be quite uncomfortable and gets dirty easily. It is entirely plausible that men would regularly shave if they had a means to even in a post-apocalyptic wasteland.
Question: Is the airplane captain supposed to be the "Gyro-captain" from "Mad Max 2"? (a.k.a. "The Road Warrior" in America) This would explain why Max says "You." when he first sees him, but I still do not know, as they say at the end of Mad Max 2 that no one ever saw him again.
Answer: The airplane captain is not the "Gyro-captain". Max says "you" in Mad Max 2 because he saw him earlier in the movie. In Beyond Thunderdome, it never says who or what happened to the real airplane captain.
Chosen answer: The train tracks would have been covered by dirt for not being used for years. The truck was already cranked, as the engine was source for the generating power and lights. The exit was boarded up and the truck ripped through it. The kids were not prepared, but did observe what the adults were doing and could have been given instructions on what to do.
