The speed between BWN-NFK is not possible even in wildest dreams, more than 200 kms in 1 hr 50 mins. Best case scenario, 2 hr 45 mins is achievable. Even SRC-BWN in 1 hr 20 mins is not possible, would have to add atleast 20 mins more. Basically your IMG train needs to slow down atleast 1 hr for it to maintain its schedule.
