Its a Sleeper class coach.
I once travelled in Coromandel's Sleeper class from BBS to BZA, it was more horrible than my Ganga Kaveri's GEN class travel from Warangal to ALD. At BBS my family struggled to even enter the coach. In the morning we could not even move from our berths till we reached BZA.
Recently also travelled by HWH-YPR exp in GEN class from VSKP to BZA, I had to stand for 4hrs in the journey of 5.5hrs. All coaches are just horrible..
