i am afraid mr venkat is wrong. there is no coupe nowadays in any train which used to be there in the 90s, but the quota is still there and so are lower berths. he can chk it out and all major trains have it. i have nt seen a cabin coupe for 6 berths for so many years now, like it used to be once upon a time, during my criss crossings all over. may be i did not come across.
