Travelled by this train recently from VSKP-WL by 2nd AC.
Started on time with from VSKP from PF#4, Loco in charge is WAP4. Started slowly from the station. After long time i boarded a train which passed through DVD,AKP with out a stop. But there are after its starting going very slowly..stopped at Tuni for signal clearance. By the time it reached RJY its 30 min. We though from there it will cover the late by BZA..But stopped at kovvur. After that its further lost its speed then went to loop line of the oposit track at PULLA station. No one knows whats happened stopped there for 15 min. So people told there is a accident, some told repair....
more...

After some we have green for oposit side train. A train with WAP4 coming towards us at 13:15 i didnt understand which train it is...Then i see its NZM-VSKP swarna jayanthi..That means this train has 2 rakes. I dont understand why a biweekly needs 2 rajes for 34 hrs journey.
Then finally our train started, finally reached almost 50min late at bza. Stopped there for more than scheduled time, i.e about 30 min. So finally left BZA with 1 hrs late. Then it started its non stop run to WL. I used my Nokia C6 for its running speed.
Before we go to speed, let me tell about the train rake. In recent year this is the only train i seen with oldest rake. The 2AC is made of 1992 refurbished coach. Its really a worst one. AC not at all working. No one taken food also. Pantry is ok. Even remaining coaches also old only.
Coming to speed, after we left BZA its started playing at 100kmph. This train upto 114-117kmph then its vibrating with scary sound. Then immediately the speed reducing to 100-90. Again touching 110 kmph then again slowing it down. Like that its almost doing at 100-110 kmph...Finally we passed KMT with out a stop which is also a new thing to me. So with some speed brakes its finally arrived WL at 18:00 with 30 min late. From BZA-WL 2hr 30 min is a good show.
Speed : 3.8/5
Comfort : 2/5
I wont recommend this train 2AC to delhi until they change that coach, even fan sound also very much horrible. Seats almost spoiled.
