Its high time for IR to introduce a Fully air conditioned Duronto between Lucknow and Mumbai LTT/Dadar/CST..this way the AC rush for direct travellers to Mumbai would be cleared for Pushpak..Additionally with CNB-JHS electrification almost complete and CR AC conversion in progress, this move will speed up Lucknow Mumbai travel by atleast 4-5 hours and make it a better travel experience not failing to mention the LHB AC rake culture of Duronto/Rajdhani these days..
