The boiler used in the plow isof the locomotive tjpe, 67^^ ins. indiameter, with Belpaire firebox and car-ries a pressure of 190 lbs. The engineconsists of two horizontal cylinderswith slide valves operated by the Wal-schaerts valve gear. The plow is car-ried on a steel I-beam frame, and thisis mounted on two 4-wheel steel frametrucks. In order to prevent the derail-ment of the plow, the front truck isprovided with ice cutters and ice cutters are attached to aframe hung on the forward end of thefro
