I think the platform numbers of these locals are not decided before hand and are not permanent or fixed.Local trains are accorded platforms according to their availability.Other members n admins from Kolkata may please confirm this.
There is no railway track point between DHK and NRPR, SBGR and MAK. So, all down trains(eg: SDAH-NMKA EMU, SDAH-BRP EMU, SDAH-DH EMU etc) gets their fixed platform(i.e. Pf#2) from PQS to MAK. All LKPR & NMKA bound trains always get pf#4 of BRP.
