One of the best maintained trains on this route. I would say the BEST train in terms of cleanliness.
OBHS does a brilliant job. While departing at night from LTT, it starts with a neat and clean rake.
Next day morning itself OBHS starts doing its job and tries their best to keep the coaches clean.
Biggest thing is they don't even...
more... ask for any "Bakhshish" in end. You can personally ask them for individual cleanliness problem or pest problem.
They will help.
Personally experienced while traveling in SL class from LTT to HWH.
