A lot of people are asking how it gets refueled. I never built the refueling and repairing system because I lost interest, but I designed one. Basically there would be another train identical to this one, and every 5 minutes they would switch places. The one not defending would pull into a giant rail structure somewhere inside the base to get repaired and refueled. A circuit clock would manipulate signals every 5 minutes to get them to reroute and switch places. There would be hardly any gap between the trains as they're switching, as well, so no weakness in the defense.
