Breaking Plows.—The ordinary form of breaking or driving plow resem-bles a large box car with an inclined front end, the plow being pro-pelled by locomotives in the rear. If the plow is run at high speed into adrift it has to stand very severe racking and wrenching strains, and notunfrequently leaves the track. This leads to continual delay in diggingout and replacing the plow. If the plow and engines strike a heavy driftthe sudden shock is likely to derail both plow and engines, or to shift thetender tanks, or the plow may run up into the snowdrift. Drifts that havebeen in place for several days should not be attacked until soundings orsome investigations have been made, as alternate thaws and freezing may.

The plow will only drive acertain distance into the drift, and must then be dug out to enable the en-gines to haul it back for another run, and sometimes one or more of theengines has also to be dug out. The dimensions of any plow in cross sec-tion should be such as to leave a clearance of 3 to 5 ins. above the rails and5y2 ins. between the plow and fixed structures, such as bridge abutments,tunnel walls, freight platforms, etc. The plows of the New York CentralRy. are 10 ft. 1 in. wide, and 12 ft. 2 ins. high from the ties, the overhangingnose being 9 ft. above the ties. Sometimes the face of the plow is square tothe track, but more commonly it is wedge-shaped in plan. The Russell snow plow, shown in Fig. 221, is extensively used. It has veryheavy framing and lateral bracing, and is mounted on two four-wheeltrucks with roller side bearings. For single track, it h
