A slow moving train b/w Varanasi/Banaras and Ranchi. I was surprised to see a single AC coach in this train. Reminded me of another crawler LJN-BJU express which used to run with a single AC coach back in the day [it runs with EIGHT now for some reason].
I honestly think they can speed up/extend this train. Or maybe, on the two days, that this train doesn't run, an extended version from LKO-RNC could run. Both state capitals remain unconnected despite not being geographically too far.
