Presently, most of the Chennai Metro City Suburban Electric trains from Chennai Beach-Tambaram to Chengalpattu operate with 12 coaches.
However, as for the other suburban electric trains operating between Chennai Central Thiruvallur and Gummidipoondi, 60% of the trains are operated with 12 coaches and the remaining 40% with only 7 coaches.
As such, activities have been initiated to make the 40% suburban electric trains also with 12 coaches!
In the first phase of this project, it is informed the task of widening the platforms of the stations in the route Thiruvallur-Gummidippundi have almost been completed,
