Comments on: Not enough snow has fallen on this sunny but brutally cold January day to get these two monsters out of the boiler house stub track in North Bay and make a run down the main line. For the time being, snow clearing duties will be left to the smaller more agile machines like the Knox Kershaw KSF940 snow fighters ONR currently has on-hand.

Ok the mystery deepens. Maybe someone from ONT Northlands past might have the answer

TMike, That stack you see is on the building behind the plow. I have other photos of this plow and there is no chimney showing anywhere on the roof. There is however piping and stencilling on the plow indicating a stove oil fill. In my 48 years of railroading I don’t recall a snow plow or flanger being equipped with an air compressor. All the plows I have been in contained large air reservoirs that were were fed by the pushing locomotives.

Hi Paul. Yea it doesnt look like a chimney at all(it has a chimney to the right),more like an air intake designed to prevent snow from being sucked in. These plows had air compressors for the wings and blade operation. Maybe its for that???

I’m not convinced that duct work is a chimney for an oil fired stove so I have asked my contact to snap some interior photos of the plow when and if he has an opportunity. Stay tuned.

Unfortunately I did not have an opportunity to go inside the plow when I snapped that photo. However, my contact at ONR in North Bay canvassed a long time shop employee who said the duct work is ‘the chimney for the kerosene heater’. Other ONR plows have the conventional caboose type chimney for exhausting the oil fired stove so I am guessing this may have been an experimental set-up.

What is the duct across the rear and top of the plow used for?
