Yes Sir. As you have rightly said, TTE's are usually strict while dealing with the premium trains. However, there are exceptions as I have pointed out in my earlier posts.

Once I and my friend was traveling by 12246. My friend was supposed to board Rajdhani till Dhanbad. I came along with my luggage to see him off. TTE's roaming around over the platform enquired to me about my coach number.

I politely told him that I have just arrived by YPR Duronto with my friend and have came over to see him off for his further journey till Dhanbad.
Upon hearing this, he sounded a bit annoyed. I had to again tell him that YPR Duronto had arrived at 4:30 pm and my ticket for Duronto still makes me eligible to be within the station premises.

As he had no further logical points, he took his leave.
