Yo guys, if you're confused about the 3ac economy coaches fare, check this out. I rode in one on April 11th on the 19666 train from udz to kurj. I originally booked a 3ac ticket, but they gave me a bunk in b7 coach, even though b7 ain't even a thing on this train. After they made the seating chart, they changed my coach to m2. At first, I was pissed, cuz I paid full 3ac price, but got 3ac economy service. But today, I checked my refund history and was pleasantly surprised to see that they refunded me 285 rupees! So don't worry if you get a seat in Economy Class, you'll get your fare difference back.

Booking for 3E class has been stopped from March 22nd. It seems like they are planning to replace it with either 3AC or SL class.

22 March se 3E class ki booking band hai. Mujhe lagta hai ki wo 3E ko 3AC ya SL se badal rahe hain.
