Right now, only Kalka Mail is the only direct train from HWH to CDG, which too is almost full throughout the year. So this chain may be helpful.

Triweekly chain from STA ,KTA ,SGO ,DMO To UMB,JRC,JAT ,Fast ,short

This chain starts comfortably at 18.40 by that time one can conveniently wind up days work and reaches next day at 21.40, so take rest and resume work at destination i.e. Amritsar, this is better than any other chain since one does not have to leave source at day time thereby leaving incomplete work, and one need not arrive at the noon time to face the blazing sun in this Northern zone, instead one can comfortably take rest, and start the following day. Even the time buffer of 2hrs. 35 mins. is pretty good. Please consider

This is the fastest chain connecting Kolkata with Chandigarh. no wastage of time and enough buffer of 3 hrs.
