This document describes 4 features of a high-tech tunnel: 1) An aerodynamic entrance to reduce turbulence, 2) Installing an air turbine parallel to the tracks to generate power from passing trains, 3) An automatic lighting system that uses a spring-loaded key under the tracks to complete a circuit and light the tunnel as trains pass through, and 4) An electrostatic precipitator (ESP) in a bypass tunnel to improve visibility by purifying smoke from diesel engines before it enters the main tunnel.
