Although DDU consist total of 08 Platforms but for Down Direction Trains only platform number 01/02/03 is fixed & rarely pf.no.04 has been used for the down Departures when there is mega conjestion of Trains at the same time (just to decrease the Load Hustle-free!) "which usually occurs at the time of Evening"
Platform number (03) is the Reversible Platform so both Up/Down Arrivals and Departures can easily took place there!
And...
more... Rest 04/05/06/07/08, is permanently fixed for UP Arrivals and Departures!
Though pf.no.05 nd 06 is the hub of DDU Based MEMUs, So The MEMUs which used to Originate/Terminate at DDU, their Arr/Dep. has done from platform number 05 and 06 only! ✅
