Doubling along with electrification is much important .Wap7 and wap5 can put out a good show here by hauling train's on time. Now that 12163 dadar Chennai egmore and chennai mail got change of traction two days back from Wadi - MAS , it helps to reduce the time atleast 15 - 20 minutes which is a bonus point.Now coming to the point i.e No.of haltings ,yes I believe it should be removed ,more no.of haltings also leads to delay in train's .stations which are unnecessary must be skipped. Now for udyan express LHB is highly impossible due to single line on Pune solapur Gulbarga.First completion of doubling is necessary on CR then can think of Humsafar duronto LHBfying etc.
