I have booked 3 2ac berths in 12370 ddn hwh sf exp for 5th July from jasidih to howrah. At the time of booking, only 4 seats were available. I have been alloted a berth in A1 while my other two family members are alloted berths in HA1. I have seen coach position and these are adjacent coaches. Want to know if these coaches are interconnected? Can I walk / move from one coach to other after boarding?
