NDG When extra Locomotive Braking is required when moving heavy cuts as in Yards, a 'Dead' locomotive can be used for it's air braking ability alone.
CN still does this, the SD40s and other six axle units that have been 'demoted' to yard and hump service are not set up to supply power to slugs, but at Mac and Symington they are commonly paired with slugs.

BaltACD NDG CN 9344, CP Ogden Shops 1967. In 1967 CP 4054 hit a Rock on Nelson Sub, demolishing former. http://cranbrookhistory.com/image_view.php?ID=33225 http://cranbrookhistory.com/image_view.php?ID=33224 ...

That would be Rock with a capital R...

Thank You.
The rock was the hard place.
Never too old to have a happy childhood!
FYI. The short stack ahead of Bell on CP 8166 is Exhaust Stack
for oil-fired Watchman Heater which keeps Diesel warm when
shut down in Cold Weather.
CP 4055 ALSO Received a STW Crest after it derailed destroying Station Greenwood.B C.
Now we only need the Montrealer, the Winnipeger and the Atlantic to complete the set!
She had plenty of warning, and chose to ignore it. That award that shall not be mentioned here comes to mind.
We're required to start our whistle/horn 20 seconds or a quarter mile from the crossing. Crossing protection is configured to meet that requirement at track speed.
Overmod NDG Another Incident. I have a somewhat different take on this -- woman driver jokes aside. There's less than 15 seconds from the time the gate finishes dropping to the time the train is on the crossing. That seems short for passenger service where the train is moving as fast as pictured. She decides to go across, then evidently sees the train coming and stops ASAP; whether she tried to engage reverse 'in time' I can't tell. But this looks suspiciously like a case where someone expected the gates to be down a longer time before the actual train arrived... oops.

Gates are DOWN - wait for the train to pass and for the gates to go UP.
What a original concept!
In any event - once you get on the tracks - KEEP MOVING
NDGAnother Incident.
Could Be!
Another Incident.
Sometimes "improved" material did not give better longevity. If I remember Steinman's biography correctly, he mentioned a great use of hardened steel wire in the wire rope and cabling used in suspension-bridge construction in the post-WWI period. This came to grief in much the same way nickel boiler steels did.
The bridge cables in Quebec are more victims of neglect than "postwar technology" design. Part of the fun is watching the shucking and jiving at upper levels about who reported this issue and when, with a certain 'wait and see' attitude entirely objectively unjustified.
It's almost to the point they can't pull cables for replacement without risking an accelerated load shedding leading to span collapse.
Perhaps that spot is haunted.
Electroliner 1935How have John Augustus Roebling's suspension bridges (Cincinnati Suspension Bridge, 1867; and the Brooklyn Bridge, 1883) lastd so long with no rusting issues? I believe his cables as I understand them are sealed in tar and wrapped with a painted cloth. No rust.
In the 19th Century 'Engineers' did not have finite knowledge of the materials they were using to build their creations - the basically adhered to the adage - If a little gets the job done for now, a lot more will keep doing the job for a lot longer. Engineers of that age wanted their creations to last 'forever'.
Mid 20th Century and later engineers now have strength specifications on virtually every material they use for their creations - they also know, in most cases, they are designing for a 50 year life span - not a 'forever' life. As such they design accordingly. These engineers are more cost concious than they are longevity concious.

Other mines used to do the same with electric locomotives, and some had portable catenary stands for track that was regularly moved around in the pits.

Edmonton's trolleybuses would climb the hills out of our river valley like they weren't even there. The GM diesel versions (6-71 Detroit with a 2-speed automatic, what a sound!) were slower but always made it, while some other designs were significantly underpowered and crawled or even stalled on occasion.

Nothing lasts like bridges built to withstand the pounding of steam engines.
blue streak 1 Actually we had a large building that had painted white a large arrow with airport name also white and mileage 12-1/2 miles.

Unless you're that guy that painted "Welcome to [can't remember the place]" on his roof, except he lives no where near the city he put there...
