Originally the city planned to use monorail on all lines but many were subsequently changed to railways as part of the Chennai Metro.
In 2006 a system was proposed in the Long-term Urban Transportation Scheme of Second Master Plan by Chennai Metropolitan Development Authority (CMDA).
Again, when the new AIADMK government came to power in 2011, the Chief Minister Jayalalithaa, through the Governor Surjit Singh Barnala's address to the assembly, stated that the Chennai Monorail project of around 300 km will be revived and would supplement the existing metro rail systems that were implemented with assistance from Japanese loans and central government funding.
The developer will be responsible to (DBFOT) design, construct, finance, own, maintain and transfer the project after a period of 30 years.
Initially, a four-car monorail train is expected to run along an elevated narrow guide way that would come up on the road median.
[11] Via Mudichur The State government has decided to drop one of the four monorail lines that were supposed to be built in the city.
While originally an ambitious 111-km long Phase-I network was proposed to be constructed the revised target means the monorail grid would be only 57 km.
The corridor from Vandalur to Puzhal via Avadi (54 km) has been axed because it runs through "undeveloped areas with no pre-existing traffic in the alignment", making it "financially unviable".
The team, comprising personnel from MTC, PTCS and a private consultancy firm, were given a time period of ten days to study and come up with sites where monorail stations can come up.
The Kathipara station will boast of the multi-modal transport system with the monorail integrating with MRTS, Metro Rail, and EMU service.
