Key Data


Kochi Metro

Kochi Metro is a proposed rapid transit system for the city of Kochi in Kerala, India. The 25.65km metro line will run from Aluva to Petta and will include 22 stations. The Kochi Metro Rail Project is also known as Komet or K-3C.

The $950m project will be operated by Kochi Metro Rail Ltd. (KMRL), a joint venture between the Central and State governments of India.

"The project will be operated under a build, operate and transfer (BOT) basis over a 30-year concession period."

Delhi Metro Rail Corporation (DMRC) and KMRL signed a memorandum of understanding (MoU) in New Delhi for executing the first phase of the project from Aluva to Pettah in May 2013. According to the agreement, DMRC will manage the technical aspects, contract orders, supervision at the project site, procurement and construction on behalf of KMRL.

The Kochi Metro will be completed in phases. The first phase of construction began in June 2013 and will be completed by 2016. The project will be operated under a build, operate and transfer (BOT) basis for a 30-year concession period.

Alstom was awarded a €85m ($107m) contract to supply 25 Metropolis train sets for the Kochi Metro.

Kochi Metro purpose and benefits

Heavy traffic congestion has necessitated the development of a metro rail system in Kochi. Buses are currently the major public transportation system in Kochi.

The new metro system will reduce traffic congestion, while providing safe and rapid transportation to commuters. It will also reduce pollution and noise levels, as well as congestion on city roads. The project will create employment opportunities for the local people.

Kochi Metrorail project details

The government of Kerala selected DMRC to prepare the detailed project report (DPR) for the project in December 2004. The project was initially expected to start by 2006 but was delayed due to poor economic conditions.

The Kerala government requested DMRC to extend the metro route to Nedumbaserry International Airport in February 2008. The proposal was approved in April 2008.

The project received public investment board (PIB) clearance in March 2012 and union government clearance in July 2012.

DMRC began preliminary works for the project following the clearance. Preliminary work included the widening of three arterial roads, Banerjee Road, MG Road and South Railway Station Road, as well as the construction of a new rail over-bridge (RoB) near KSRTC station and a foot over-bridge.
