Actually the train stops at many stations on the way, to give side to other trains. Now, if this train was given priority then it will reach the destination very early. In fact, in my earlier blog also I had mentioned about it. But somebody replied stating the destination station is jampacked as many trains orginate and depart during that time and hence trains have to be stopped at various stations etc. If this train (12223/4) is given only technical halts and also one or two halts in between, it will be the fastes train to reach ERS from Mumbai, say probably in 2o hrs or even less.
