Spelling out the necessity for its so defining it was recorded: "The introduction of section 2(28A) defining the expression 'route ' appears to have been necessitated to dispel the confusion consequent upon the seeming acceptance by this Court in Nilkantha Prasad and Others vs State of Bihar, [1962] Supp. 1 SCR 728 of the suggested differences between 'route ' and 'highway ' by the Privy Council in Kelani valley Motor Transit Co. Ltd. vs Colombo Ratnapura Omnibus Co. Ltd., where it was said, 'A "highway" is the physical track along which an omnibus runs, whilst a "route" appears to their Lordships to be an abstract conception of line of travel between one terminus and another, and to be something distinct from the highway traversed . there may be alternative roads leading from one terminus to another but that does not make the route any highway the same. ' The present definition of route makes it a physical reality instead of an abstract conception and no longer makes it something distinct from the highway traversed.
