Here are some key dates in CMRL's history:

Chennai Metro Rail Limited (CMRL) is headquartered at the MetroS building in Anna Salai, Nandanam. The company is headed by a board consisting of 12 directors, which includes the chairman and the Managing director.

The main operational control center (OCC) is located in Koyambedu, where the movement of trains and real-time CCTV footage obtained is monitored. This helps ensure the smooth operation of the metro system.

CMRL operates two colour-coded lines covering a length of 54.1 km (33.6 mi), making it a significant transportation network in Chennai. These lines are a testament to the company's efforts in providing efficient public transportation.

The depots at Koyambedu and Wimco Nagar house maintenance workshops, stabling lines, test tracks, and a washing plant for the trains, which are essential for the upkeep of the metro system.

The Chennai Metro Rail Project is a vital part of the city's transportation infrastructure. The project aims to provide a reliable and efficient public transport system to cater to the city's rapid urban expansion.

Chennai is the capital of Tamil Nadu and has a unique blend of industries, with the port being an established manufacturing centre, notably for the automotive industry. This has contributed to the city's growth, which is less attributable to high technology and the service industries compared to other Indian metropolitan areas.

The metro rail project learns from the experience and practices in Delhi, one of the world's most successful modern urban rapid transit schemes. The project consultant was the Delhi Metro Rail Corporation Limited (DMRC), which helped plan the new metro to be built to 1,435mm gauge.

The first phase proposal included two corridors to integrate with existing public transport services, including the heavily used bus terminal and Central station. The lines are a mix of underground and elevated alignments, with around 55% being underground.

A ballast-free slab track was proposed to reduce maintenance, with a 750V dc third-rail power supply.

The Chennai Metro Rail Project was a massive undertaking that required careful planning and execution.

The project was launched on June 22, 2009, with the laying of the foundation stone for the first phase by the then Chief Minister of Tamil Nadu, M. Karunanidhi.

The first phase of the project was divided into two corridors, with the first corridor connecting the city's central business district to the southern suburbs and the second corridor connecting the city's central business district to the western suburbs.

The Chennai Metro Rail Project has been making significant progress.

The first phase of the project was completed in 2015, covering a distance of 45.6 kilometers.

The project was initially expected to be completed in 2013, but it was delayed due to various reasons.

The second phase of the project was completed in 2019, adding 21 kilometers to the existing network.

The Chennai Metro Rail has been a game-changer for the city's transportation system, reducing travel time and increasing connectivity.

It has also created a significant number of jobs for the local population.

The project's success can be attributed to the collaboration between the government and private agencies.

The Chennai Metro Rail has been a model for other cities in India to follow.

Chennai's rapid urban expansion has led to unacceptable and unpredictable journey times by road, making a metro rail project a necessity.

The city's growth is less driven by high technology and service industries, but its port is an established manufacturing centre, particularly for the automotive industry.

Chennai's metro project draws inspiration from successful urban rapid transit schemes like Delhi's, one of the world's most successful modern urban rapid transit schemes.

The metro will supplement existing 1,676mm gauge operations, which are mainly geared towards passenger activity, and will also work alongside the city's three-route suburban railway.

The free-standing 25kV ac overhead-equipped Mass Rapid Transit System (MRTS) on mostly elevated alignments is still under development, but will be an integral part of the city's transportation network.

The Chennai Metro Rail Project's Phase One was a significant undertaking, with the Delhi Metro Rail Corporation Limited (DMRC) serving as the project consultant.

This phase included two major corridors, one of which was the 23.085km Blue line between Washermenpet and Chennai International Airport.

The Blue line extension added an additional 9.051km from Washermanpet metro station to Wimco Nagar.

Corridor 2 ran west and had an interchange with Corridor 1 at Alandur, spanning 21.961km between Chennai Central and St Thomas Mount to the south.

A connection with Corridor 1 was also established at Chennai Fort.

Around 55% of the lines in Phase One were built underground, while the remaining sections were elevated.

The project used a ballast-free slab track to reduce maintenance, and a 750V dc third-rail power supply was implemented.

The Chennai Metro Rail Limited has made significant strides in infrastructure development. The project consultant, Delhi Metro Rail Corporation Limited, played a crucial role in planning the new metro.

The first phase of the project included two corridors that would integrate with existing public transport services. These corridors are 23.085km and 21.961km long, respectively.

One of the corridors, the Blue line, runs between Washermenpet and Chennai International Airport, with a current suburban railway link at Tirusulam. The Blue line extension is a 9.051km addition from Washermanpet metro station to Wimco Nagar.

Around 55% of the lines are underground alignments, while the remaining are elevated. This mix of alignments allows for efficient and safe transportation.

A ballast-free slab track was proposed to reduce maintenance. This innovative solution would make the metro system more reliable and cost-effective.
