But already that route is more focused for Delhi-Mumbai trains and trains coming from Kerala,Konkan,Maharashtra pass via Vadodara and take loco change and you know along side of TVC Rajdhani, Mumbai Rajdhani,Goa Rajdhani many trains take that route only. Many trains coming from Konkan,Kerala and going towards Bikaner and Jodhpur and adding more trains towards Delhi will congest that route according to me. For that Railways should think of starting more Jaipur,Ajmer trains via Ahmedabad.The maximum speed which Mumbai Rajdhani catches is almost 140km/hr and you cannot expect the same speed in Ahmedabad-Ajmer-Jaipur-Delhi route max is 120km/hr.
