Its been two months since this, now it was the time to test. The bag is big enough for the frame and other bike stuff, has two pocket on both sides for tires. The packing itself is a big task, need extra care to pack. What I worried was the damage on frame and spoke. Finally bag was packed using extra card box parts on both sides of frame, some loose papers. The bag should have come under the seat, didn’t try though.
If it would have been regular 2AC, things would have been different, people carry hell lot of luggage while travelling in railways. I was lucky enough to get a nice seat. Ticket was booked in 2AC; got boggy half 2AC, half 1AC and seat, exactly at the joining point of these two.
