Drummonds Front End Arrangement for & South Western Railway. DRUMMONDS FRONT END ARRANGEMENT FOR LO-COMOTIVES. London & South Western Railway. Through the courtesy of Mr. Duggald Drummond, chiefmechanical engineer of the London & South Western Railway,drawings of his new patent draft arrangement for locomotiveshave been received. It is attracting wide attention abroadbecause of its fuel saving and spark arresting qualities. The purpose of the arrangement is to distribute the effectof the draft from the nozzle over a large area in the smokebox. The greatest suction of the smoke box gases is aroundthe exhaust nozzle. Mr. Drummond has surrounded the noz-zle with a cup having wings at the sides. These wings are intwo portions, the lower portions being hinged to give accessto the tubes. These wings are closed at the bottom, so thatthe gases are drawn from the sides of the smoke box over suchan area as to allow them to escape fre
