Yes... In Olden days Passenger Trains are only designed for "poor People"..
Now railway is changing the Trend(Important Passenger Trains for RICH)
Like Train 0563 and 0564 Passenger Trains have AC Coaches(This is VVIP Train from "Hyderabad to Nanded") and well maintained.
Similarly there are many Passenger trains with runs with AC Coaches and with "WAP 4/WAP5 and even WAP 7" Engines
