That's how I understand it.The nose/tail helps mitigate pressure spikes which could occur upon entering or leaving a tunnel.When running in reverse direction,the nose/tail does likewise.
The tunnels themselves are crossed-drilled,like a muzzle-brake, with air shafts at strategic locations to further aid pressure bleeding.
Good news for eardrums!
