चलती है (ग्वालियर-भोपाल वाया गुना बीना ICE) उड़ती है धूल जलते है दुश्मन खिलते है फूल - Adi Singh

This is how Coro & Mail run. I once travelled from BBS to BZA in Coro, one could not even get up from their berth in the whole journey. Horrible journey, but this problem was not there when I travelled between MAS and CLX in Mail.
I also travelled in GangaKaveri from WL to ALD in General class, I would say GK's General was much better than Coro's Sleeper class.
