To be really accurate, it should replace MGR by Marudur Gopala Ramachandran. Maybe one could add Menon at the end.

Kalaignar Dr Muthuvel Karunanidhi Egmore* Railway Station
Puratchi Thalaivi Dr Jayalalithaa Jayaram Amma Tambaram Railway Station.
*Eshumbur if one uses the original Tamil name, as you can see from the Hindi sign here:
If this picks up in the rest of the country, there would be further new names such as Atal Behari Vajpayee Gwalior and (God forbid) Pratibha Patil Amravati.
