4 Integrated Route Selection
4.0.1 Railway route selection design shall be performed based on comprehensive research on the
related plannings as well as topographic and geological data of regions along the project route；the
urban development, industrial distribution, project condition, and environmental sensitive points of
regions along the route shall be fully taken into consideration, and the track alignment shall be
determined based on technical economy comparison.
4.0.2 Railway route selection design shall meet the following principles.
1 Comply with the integrated traffic network planning, railway network planning and other
relevant plannings.
2 Pass through the main cities and major towns to coordinate with urbanization
development and industrial distribution.
3 Connect smoothly with overall urban planning and other transportation means, and facilitate
comprehensive land development along the railway.
4 Comply with the requirements
disaster prevention and reduction, land conservation, preservation of cultural relics as well as social
stability.
5 The railway should share the transport corridor with other transportation means so as to
the land partition and methods shall be reasonably selected in consideration of urban function division, landscape requirement and environmental influence, etc.
6 Avoid or bypass various unfavorable geological structures based on topographical, hydrological
and engineering geological conditions；reasonably determine the engineering types and treatment
project safety and operation safety.
7 The influence of existing highway (road), building (structure), high voltage electric corridor
and other facilities shall be fully considered, and the engineering quantity of demolition and
reconstruction shall be reduced.
8 Comply with requirements on safety distance and safety protection about flammable and
combustible materials as well as radioactive substances.
9 Comply with requirements of military facilities and national defense.
10 New technologies, new approaches and new selection design.
4.0.3 The railway line that is led in a terminal (area) shall comply with the planning of general view
of terminal, shall be adapted to the functional orientation of passenger station, shall be connected with freight station and railway logistics center, and shall accord with the major passenger and freight flow direction.
4.0.4 High-speed railway should pass through the county-level cities or above. Intercity railway
well as main city clusters, and shall also give should pass through major cities and
consideration to the combined transport with airport.
4.0.5 The site selection of station shall comply with station distribution principle, shall meet the
transport demands, and shall be in accordance with urban planning and transportation system；the
factors shall be fully taken into account like natural conditions, demolition of existing buildings and
integrated land development.
4.0.6 In railway alignment design, the factors like railway section design speed, speed difference,
comfort level and maintenance shall be integratedly taken into account；it is necessary to pay attention to the design of geometric shape coordination between route plan and profile.
4.0.7 Railway line shall avoid or bypass the environmental sensitive points like natural
areas, landscape and famous sceneries, water source conservation areas, cultural relics and historic
sites: or pass from the edge of those environmental sensitive points by using reasonable manners if it is difficult to avoid or bypass them, and corresponding procedures such as administrative approval shall be implemented.
4.0.8 In railway alignment design, the embankment height, cutting depth and earthworks slope
height shall be reasonably determined. For the case of railway route selection in hilly
mountain areas, the slope should not be cut and excavated deeply; for the case of railway route selection in plain river network region, the river course and lakebed should not be occupied ,so as to reduce the impact on the natural ecology and on the environment.
4.0.9 The railway alignment scheme across big rivers shall comply with the requirements of
navigation development planning as well as flood prevention and navigation channel. The
sharing of the corridor of bridge site, bridge location and bridge type shall be fully taken into
