What is Scale R or Scale S, etc., in the context of parcel service?
IR has several freight rate scales for parcel traffic. Scale R or Rajdhani Parcel Service is applicable to parcels carried on the Rajdhani Express trains and thereby being assured of the speediest delivery of all IR’s services. Scale P (Premium Parcel Service) applies to parcels carried on certain Shatabdi Express trains, certain other Mail/Express trains, and all Special Parcel trains (including the Green Parcel vans, Blue Parcel Service, etc.). Scale S (Standard Parcel Service) applies to all parcels carried on other passenger trains. There also used to be a Scale E (Economy Parcel Service) which was applicable to parcels carried on ordinary passenger trains, but that has since been abolished [3/05] and the category merged with Scale P. Newspapers, magazines, and certain other goods always get classified as Scale S traffic (earlier, Scale E).
