The proposed Vande Bharat between Chennai and Kottayam is expected to have eight coaches.
The project also moots cab arrival/departure facilities to passengers at stations; wheelchairs and buggy drive assistance.
To restore the pre-Vande Bharat timings of these two passenger trains, the Railways also moots an alternative option.
The Shanghai Maglev is the fastest train in the world.
These sleeper coaches have been designed to meet the requirements of long-distance travellers and the facilities would be better than those in Rajdhani Express trains, said authorities.
It has 22 coaches - 12 sleeper non-ac coaches, 8 general coaches, 2 luggage coaches.
There are many allegations that the service is delaying other trains in Kerala.
The changes are apparently part of the recently publicised timetable, according to the Railway.
The Vande Bharat Special train will run on Friday, Saturday and Sunday.
Says it violates people's right to travel.
