There is already a 19607/08 Ajmer Kolkata Express & 18009/10 Ajmer Santragachi Express present on the Route on which it runs.
Also Either one of them will Strictly follow the RTM-FTD-INDB Gauge Conversion Work So no Problem.
But From Ahmedabad to Kolkata With Such a very long route with so Much time taking is Just a waste of Money and time too.
