Operational Specification

• Safety

EU Common Safety Method (CSM)

• Capacity

Up to 18 services per hour each way on the core

Up to 1100 passengers per service

• Availability

Operational hours 0500 – 2400 (0800 - 2400 Sunday)

• Reliability

Average delay less than 30 seconds per service

• Connectivity

Journey times based on up to 360km/h maximum speed – balanced with environment impact

Whole-journey time reduction – station design / service frequency

HS2 Design Principles

32

HS2

Outline Design of Major Elements

33

Design Components Include

• Stations, buildings & associated public realm

• Earthworks including for visual/ noise screening

• Structures, bridges, viaducts and tunnel portals

• Retaining structures

• Boundary & security fencing

• Noise barriers

• Lighting (urban and rural)

• Planting for visual screening

• Tunnel ventilation & sire safety

• Diverted watercourses/ balancing ponds

• Footpaths and highway infrastructure

• Operational compounds, substations etc.

34

EIA / Environmental Statement

• Comprehensive mapping

• Key Policies Sustainability Policy – sets HS2 Ltd’s approach towards

environment – balanced, proportionate and practicable

Environmental Design Aims

Code of Construction Practice – set out the measures to protect people and natural environment during construction

• Technical Annexes – assessment of the scheme under 14 topic areas From Air Quality to Waste Materials
