Didn't know about originating from DEE , if so then damn sure not allowed in AC class as many trains of DLI originate unofficially from other nearby station but AC coach lock open at DLI...
Yes it originate from pf16 mostly
And for pf16 side entry daryaganj road.. well better to enter from chandani chowk side as distance from pf1 to pf16 is not so far bcoz at old delhi bcoz many pf were terminal type hence hardly 100-150m difference between pf1 and pf16
