What surprised me is that this train was not converted yet to an LHB version where large number of SL coaches are trimmed in favor of 3A coaches. It had 9 SL coaches in it's ICF form and only 3 3A coaches. So, there was lots of non AC space for folks to move to. But, they just crowded 3A. The worst was when the train had an unscheduled halt at Govindpuri, I guess and lots of folks just barged into the coach. Apart from the single 2A coach, nothing seemed off limits.
