I couldn't book in Tatkal in this train.
In just 3 minutes, the status in 3AC class came to WL 3.
The status came to heavy WL in just 20 minutes -
CKWL# 23 / WL# 23 (in 3rd AC class)
CKWL#...
more... 9 / WL# 9 (2nd AC class)
CKWL# 97 / WL# 80 (Sleeper class)
.
48 seats are there in Tatkal quota for 3AC class in this train.
It took time at Payment Details page in providing the Credit Card details.
.
I wanted to booked from SSM/Sasaram to WL/Warangal.
(Warangal to Hyderabad decided to travel by AC bus)
.
I hope this helps to you if you try to book in Tatkal.
