Baldwin Locomotive VVoiks, Builder high starting tractive force. In the pres-ent instance, due provision has been madefor this, as the boiler provides 240 squarefeet of water evaporating surface foreach cubic foot of cylinder volume; whilemaking the usual allowance for the super-heating surface, the proportion is 319square feet. The ratio of grate area towater evaporating surface is as 1 to furnace contains a security sectionalarch, which is supported on four watertubes. The superheater is of the Schmidt topheader type, with 32 elements; and thesuperheating surface amounts to 760 The superheated steam is conveyedto the steam chests through outside steampipes, and the distribution is controlledby 14-in. piston valves. These are drivenby the Baker gear, and are set with alead of % in. The cylinders are pro-vided with vacuum relief valves, and with box, where the rear frames are splice
