When rake cleanliness, maintenance and availability of proper catering is the topic of discussion, three trains of Northern Railways, Delhi division are significantly aweful:

features of these trains (applies mostly to sleeper class):
1) Availability of catering is dubious. Though Dhauladhar doesn't need it but absence of catering in NDLS-PDY is a torcher. Similarly though NDLS-MLDT claims to have catering, I, at times found it missing. Plan accordingly. Bring your own food.
2) Toilets. HORRIBLE. No cleanliness, nothing. (Now I can't even say bring your own toilet)
3) Designation of coach numbers is not proper. The coach that says 'S5' may not be 'S5'. The coach on which the chart of S5 is stuck is S5. Frustration inducing negligence at its apex, isn't it?
4) Rakes are extremely dirty and ill-maintained.
5) Charging points: Well after reading point 1 through point 4, you're intelligent enough to predict. If you get one, you're one of the lucky chosen ones.
