Underground Tunnel Rail System
The underground tunnel rail system refers to the alleged combination of deep subterranean tunnels and high-speed electromagnetic rail (maglev) systems that witnesses and researchers claim connect Deep Underground Military Bases (DUMBs) across the United States. The concept encompasses both the physical tunnels themselves and the transportation technology operating within them.
