Tunnel ventilation system: The purpose of the tunnel ventilation system is to provide a tenable environment within the tunnels. This will include the delivery of the tunnel ventilation system using predominantly large axial fans in shafts (within long tunnels) and jet fans in the shorter tunnels. M and E subsystems: The purpose of the M&E subsystems is to provide other rail systems with power supplies and monitoring. The M&E systems include active and passive fire safety provisions within tunnels, tunnel cross passage door installation in bored and cut and cover tunnels, tunnel lighting and low voltage (LV) distribution, Longitudinal handrails in tunnels, tunnel SCADA systems and remote monitoring of equipment in shafts and key equipment in the wayside, points heating and junction lighting.
