I agree.Pune Duronto is by far the best train from Pune with an avg speed of 76 kmph overall.Between Vasai Rd and Nzm, it has an average speed of about 83 kmph.It is only because of the bottlenecks in VasaI rD Pune section, its average speed reduces.By far it is one of the most successful Durontos running in IR.
