Well, the distance is 56 km, so at 110kmph it'll take 30 minutes. But the train also needs time to accelerate and decelerate every time there is a speed restriction and also at the originating and destination stations ( A WAP4 will take around 5-6 minutes to accelerate to 110kmph from zero and a comparable time to decelerate to zero from MPS). There are 8 stations in between, so I think there might be at least a few PSR's. And clearing the station at Dausa and entering the station at Jaipur will also take 4-5 minutes a piece. Even if you run for as much distance as possible at 110kmph, 40 - 45 min is a minimum unless the loco-pilot is able to control the locomotive with 'utmost' precision!!
