Exactly, in the letter it's written that this speedup is done to provide connection to passengers from Rajasthan to Chattisgarh area, and the arrival of Dayodaya is after the departure of both BJU-G and INDB-BSP that too at station which is atleast 2-3 km far from the other 2 trains halting stations. How passengers are going to interchange when the trains are already departed. This logic only WCR knows.
