There should be an additional field on the train details page which mentions what the train is named after.
For example: 10103 Mandovi Express: Named after the Mandovi River which flows through Goa (the destination of this train).
12619: Matsyagandha Express: Means the fragrance of fish which is the speciality of the konkan coast through which the train passes.
This...
more... would be very interesting for users to know about the origins of the names of many trains.
Kindly consider this request.
