This speed up they could have done before also.Much before lock down 22633 TVC-NZM was covering TVC-NZM in just 48 hours.This train some times reach before time also at NZM end.That too with ICF coaches.22633 also cover BSR to NZM in 18 hours 40 min in its regular run.I'm not sure how NZM timing for 22653/4 (06083/4)will be maintained during Monsoon TT as it has just 6+ hours TAT at NZM end.Eagerly waiting for the TT of 22655/6.Hope it won't get short terminated at ERS (There was such a proposal at IRTTM 2020)
