Total Seats in 3A
72 X 16 = 1152
Assuming 20 seats are occupied by TCs & Railways,
Total Passenger seats: 1132.
Now current availability gives the true picture as no other...
more... quota remains, only 300 seats vacant in ALD-NDLS Humsafar, means 1132-300, that means, 832 people are traveling by HS at the given date.
Seems to be a popular train.
