I had the misfortune of travelling on this train on the 4th of October. The scheduled departure is 15:00 hrs however it didn't budge untill 16:10 hrs.
The TTs were as clueless about the delay as the passengers. They told us that the train never departs on time as it has to make way for other 'regular' trains like Ashram Exp and a few more to pass through before starting its own journey.
It stopped again between Bijwasan and Gurgaon for 10-15 min. Ran like a horse between Gurgaon & Dausa...
more... but suddenly stalled at Dausa for 15-20 min.
It ultimately arrived at Jaipur Gandhinagar at 21:30 instead of the scheduled 19:45.
So, if you're running on a schedule or have to catch a connecting train/bus etc, then it wouldn't be advisable to travel on this train.
