Nothing as such. For the next run (within 4-5 days) both JBP and HBJ SRC Humsafars have just around 50 berths booked. Not to be forgotten that this is the case when JBP already has Shaktipunj as another Kolkata train.
Astonishingly INDB LPI does not even have that much patronage. Even INDB Puri (the first train from INDB to CG and Odisha) is getting just around 100 passengers.
