Avoid B4 (guess it was made in 98) as it is close to SL one side of the path to and toilets are always occupied by SL or UR people.
As the train crosses Andhra in daytime pathways near toilets get packed with UR people and some sneak in and sit in berths.
Beddings were good.can't expect more in trains in this region. But pillow size is too small...good for kids.
AC...
more... was maintained well, two power points one each on either side are available.
Overall it is ok and not as dirty as some other trains in this region.
Hard to see onboard cleaning staff.
Food was served by some caterers named Food on Wheels or so. Veg meals was 125/-.
