Trains originating DR may not use PF 5. Over a decade back, they had tried the idea by starting some special trains from PF 5 but never after that. Over crowding was sited as the reason. Presently, trains arrive and depart from PF 5 almost till 00:30 (last being 10193). 12133 actually skips Dadar. If started from PNVL, it could readily be a 24 coacher, and chase ERS Duronto all the way till MAJN. Under present scenario, it will remain the way it is till TNA-DIWA new lines are commissioned.
