I travelled in 19718, CDG JP recently after change in timings.. I am amazed, for obvious reasons, train's patronage shooted up high..
Similarly now timings of this train should also be changed.
It should be made a perfect Overnight train.
LJN-CNB may have some issue, but rest of the route shouldn't have much problem.
Since...
more... its days of arrival at JP are Su, Tue, Thu.. Its slot can easily be shared with either HW-UDZ Triweekly Express, or ASR-AII Express ( rest 3 days, making it a daily slot) from BKI to JP section.
