14555 can be converted in such a train but due to it's rake sharing with forward train to Una, not possible.
So another train can be started from TPU or PBE via CH-MB upto ANVT. Return journey can be done on counter timing of 14315. Starting 4-4.30AM from ANVT and reaching TPU or PBE in noon time.
But as usual NER will not explore such option.
