On the date you said, as per IRI Arr/Dep History, it covered 288km distance between AD/Adoni and VKB/Vikarabad Jn in 04 hrs 13 mins at 68.3 kmph average speed, which is higher than the max. speed you said. How's it possible? The Arrival/Departure data may be wrong by a few minutes but still the speed would be greater than 60. Don't take it in any personal way but statements like this may give false impression to people searching for the train.
