Very interesting story NDG. Amazing what some people wil steal, and sometimes for no apparant reason. Like Mount Everest, "Because it's there?"
Thieves have tried to steal bronze cannon from some of the Civil War sites around here, typically without success. 1300 pounds of gun barrel is pretty tough to move without calling attention to yourself!
Thank You.

Terrific commentary. I especially liked the review of the U-4's streamlined casing (it just blew hot air into the cab!). And the novelty (to coal men) of sanding the flues on a oil-burner, I suppose cinders would perform the same function naturally on coal-fired engines.
That video contains footage from the final operating days of 6000, the first steam locomotive purchased new by Canadian National, and also 6079, their last.

tree68 BaltACD Why is a 74 year old person taking a drivers test? I believe it's pretty common, actually. I've seen some folks in that age range who had no business being behind the wheel. I think if they've had some sort of incident it may be required as well.

It would be ironic if the individual was 'sentanced' to driving school account of not paying proper attention to railroad crossings on the highway.
Never too old to have a happy childhood!
Merci!
And just think: if the First Nations protesters had targeted the St. Jerome line instead of Candiac, both the driver and inspector would be fine today!

NDGEnd of Steel. Looks like a Wall?? https://i.insider.com/5ae100dc19ee864c008b46ee?width=750&format=jpeg&auto=webp Thank You.
Looks like a big screen wind break.
Yeah they sure are. Any structure using the terms 'long and wall' together and the Chinese will be there.
Miningman A new long wall method developed by the Chinese. Did not know they had it going.
Well, they would be the experts, wouldn't they?
As far as I know Wolverine is the only mine currently operating at Tumber Ridge.
HD Mining's Murray River project got permission to bring in foreign workers several years ago for their 'unique' longwall mining method, but that project was put on hold when coal prices were low, and I am not sure if it was ever reactivated.
They open, they close, they open , they close!
That one operating Mine is that the one with the Chinese Miners and speaking Mandarin is the reason why? A new long wall method developed by the Chinese. Did not know they had it going.
The Tumbler Sub was not idle for long, another company resumed mining not long after Bullmoose's 2003 closure.
World coal prices dropped dramatically in 2013-14, and all the northern BC mines closed again, along with the Grande Cache, AB and Line Creek, BC (near Sparwood) mines. But after a few years prices rose again, and the Tumbler Sub was reactivated in late 2017. It remains in operation today.
Current trains normally consist of up to 116 aluminium rotary-dump cars powered by three GE AC locomotives, in a 2x0x1 configuration on loaded trains.
CN did not make any friends by dragging its feet on repairing and reopening the railroad:

Electroliner 1935--- On August 19, 2000, the Quintette mine closed, and the portion of the Tumbler Ridge Subdivision between Teck and Quintette, British Columbia, was abandoned. The last electric locomotives ran along the line on September 29, 2000, after which the line was worked by diesels. The Bullmoose mine closed on April 10, 2003, after which the remaining 69.6 miles (112.0 km) of the Tumbler Ridge Subdivision between Teck and Wakely was abandoned, although the track is still in place. The electric locomotives were shipped south to Tacoma, Washington, where they are being dismantled by CEECO Rail Services. One of the locomotives (6001) was purchased by the Paul D. Roy family and they donated it to the Prince George Railway and Forestry Museum in Prince George where it is being preserved.
The town is still there pop. ~2,000. It relies mostly on tourism, hiking trails and natural beauty. Also excellent dinosaur fossils found in the area are a draw.
The Mines are all on Care and Maintenance, which allows them to start up again on short notice.

Jumping forward a few decades, here's an early drawing of the EMD electric units that were produced for BC Rail's Tumber Ridge line.

Schmidt system. As noted, Canadian Pacific had a Selkirk with a similar arrangement.
This got around the issues of high-temperature heat transfer by minimizing the potential issues of scale and oxygen in feedwater by using 'powerplant' thermodynamic design without need to condense oily cylinder exhaust. It used a sealed circuit of distilled, degassed water (at 1200-1600psi!) which transferred heat to a high-pressure watertube boiler (at 850psi). There was also a LP boiler of cheaper firetube construction. The HP cylinder (as you might imagine) was very small, I believe something like 10" diameter, and the two LP cylinders were fed by a mixture of HP cylinder exhaust and 'bottoming' mass flow from the LP boiler, both I believe appropriately combustion-gas superheated.
You almost have to make up a heat-balance diagram to see how all this worked; there may be something on the inimitable Douglas Self site (perhaps in conjunction with the ill-starred Schmidt locomotive LMS Fury) that shows the idea and the technology needed to implement it.
Reductions in fuel consumption and 'feedwater' water rate could be substantial. But -- as noted -- crews apparently did not like that nominal pressure; it did not help at all that on the HS-1a there was a very large steam gauge with a very prominent hand pointing at 850psi.
Apparently on test the thing happily ran at Hudson speed. However, in order to do that, the thrust from the three cylinders would have to be balanced at that rpm as well as reasonably equalized in net thrust. This would NOT be something I'd expect most contemporary NYC engineers to care to do "continuously", as 'mecaniciens' did on the de Glehn-du Bousquet 4-cylinder compounds.
On top of the potential operational issues it was just never cost-effective as the 'next big thing' in cheaply-fueled maintained-at-lowest-cost American power. (As was high pressure in general ... or duplexing as a reducer of augment forces.)
You may compare the details of these locomotives with the GE high-pressure design a decade later: it solved the HP feedwater issue by using a full condensing cycle at 1200psi mass flow asynchronous with road speed, and the power-transmission problem as the Heilmann locomotive did, with full electric drive.

Thanks, NDG. Makes me wonder what kind of minds came up with that complicated arrangement.
