Canadian Big Boy
This picture is Penzance Saskatchewan 1947. Three CNR ten wheelers, and auxillary water tenders.
May I respectfully suggest it is an all CP Consist.
Mountain Plow being used as drifting snow can set similar to concrete and be walked upon. Kind of snow that can be cut w/ knife to build winter shelter out of snow blocks.
Locomotives coal burners and coal bunkers covered to keep fuel dry and snow blowing into cab from rear thru cab curtains at speed. These are Tank Car conversion water cars. Hand rail on roof to enter/exit plow in motion, or stuck in drift.
A flat land plow's visor would hit deep snow, and raise plow, or get broken. Snow is not always soft and fluffy.
Many CP plows and Spreaders had cast off Steam Locomotive Headlights into Eighties. Replaced as 375 W Locomotive Bulbs no longer made and Diesel sealed beams available and 'Standard'.
Garbage Can Geeps had screw in bulbs, and most changed to sealed beams. A topic in itself.
( I walked across a snow slide in the Mtns. full of sticks and rocks, every piece sharp, the debris field as solid as concrete.
A fall would have meant instant impalement. After 50 feet or so, I walked back to truck side, descended and walked around toe. Have photo, just have to find it. Reason Rotarys had problems re trees, rocks and Mountain Goats or Sheep. )
Small sign w/ two holes, Signal Yellow, by switch points indicates 'Close Clearance' to Trainmen riding car sides, e g Loading Ramp. Post by switch stand to hold Shovel and Switch Broom above snow level. Switch Brooms had a Chisel on top end to break out ice in points.
From an 'Operating' point of view one can see the Delay when taking water. Say each 'tank' needs 4000 Gallons x 6 spots and filling. Hope water tank not frozen and had 24,000 Gallons in it.
Turning whole consist on Wye would be a thrill, esp if tail too short.
A turntable would be worse, esp if Pit full of snow.
These are 4-6-0s. Heavier locomotive may be prohibited re bridges, turntable length., etc.
