Metro Station will be elderly friendly and physically challenged friendly. Minimum of one escalator and one lift will be provided at all stations. In-situ-construction method has been adopted in MRTS whereas in Metro Rail project, segmental construction technology will be adopted. Segments will be cast in casting yard and shifted to the required place and launched as and when required. MRTS has tracks on surface and at elevated level, whereas Metro Rail will have tracks on elevated and in underground tunnels.
MRTS works on line side automatic colour light signalling arrangements whereas Chennai Metro Rail Project will have cab signalling arrangement. Trains in MRTS system have headway time gap between two trains of 10 to 30 minutes whereas in Chennai Metro Rail system, the trains will have headway of around 3 to 5 minutes. In MRTS coaches are designed to have more sitting and less standing whereas Metro Rail coaches will be designed to have more standing and less sitting.
Metro Rail will have a safer automatic door closing and opening system which is presently not available in MRTS. Coaches in Metro Rail system will be provided with station indication display and announcement systems, which is presently not available in coaches of MRTS system.
Most of the roads in Delhi are wider and the foot paths are wide enough to accommodate the Metro stair cases, lifts and escalators on foot paths.
Compared to Delhi roads, Chennai roads are narrower and foot paths are also very narrow. Set back area between the road and the buildings at the station locations are very narrow in Chennai.
Hence special precautions need to be taken during construction. Delhi Metro Rail Corporation was our interim consultant and now they have been appointed as Prime Consultant.
The technical and execution problems faced by the Delhi Metro during the construction, operation and maintenance will not be there in the Chennai Metro Rail Project, as necessary changes in the designs have been incorporated based on the experience and advice given by Delhi Metro Rail Corporation.

Hence, there will not be any disruption to these services. There are sewerage, electric cables, telephone cables and water pipe lines underground. Will they be affected while boring tunnels? How deep will the tunnel be bored? There will be a minimum of 9 meters clearance from ground level to tunnel level. So it will not affect any of the utilities in underground.
