DEVELOPMENT OF COLACHEL PORT AT TAMILNADU
FINAL REPORT
10. CONNECTIVITY PLANNING
10.1. INTRODUCTION
As stated in chapter on Key imperatives, transport linkages with the port hinterland are a key factor for the success of
the project. One million TEUs are expected to travel from or to the port hinterland, and suitable connections by road
and rail must be developed to facilitate this traffic.
Next sections show a first approach of these linkages to assess their feasibility, preliminary calculation of costs, land
requirements and to allow an initial environmental and social impact evaluation. Further studies should be developed
to optimize this preliminary design in order to reduce the impact on housing and properties. These studies are
explained in section 15 of this report.
10.2. RAIL CONNECTIVITY
A 20 or 25% of the gateway traffic is expected to travel by train. That means around 0.25 Million TEU or 3.85
million tonnes in 2020.
A single lane broad gauge track runs parallel to the west coast of India. Several alternative layouts of a new railway
which connects to the existing one have been analyzed to know which is better in terms of environmental impact,
length, slopes, and earthworks.
All alternatives have been chosen according to the following criteria:
• Avoid densely populated areas.
• Limit the maximum slope to 0.12 %.
• Limit the minimum radius to 500 m, apart from connections on the existing railway and the port.
The most suitable two of them are shown in the figure 146.
