In recent years high tensile steelhas replaced iron in many cases, but mani-festly the strength of the couplings mustbe considered that of the weakest untilsuch time as all vehicles are equipped with,something stronger. It is estimated thatto strengthen up the drawgear, replacewith high tensile steel details and general-ly improve the present coupling and buffing,arrangements to meet the wants of trainsof tons behind the tender will cost$45,000,000,00, whereas, to equip the wholestock with couplers of M.
