1 old 78 that I liked was Spike Jones & the City Slickers William Tell Overture.

Cheers.


A classic. I have it on CD, another reason I didn't hang on to the 78s.

Taking a more-awake look at it, it would appear that 7273 can attach to a slug at the front end as well as the rear. Those big cables are not standard.


Makes sense for a yard shifter, especially in this yard. This is the new style Canadian yard, probably 20 miles long and includes several sawmills, refineries, and large loading docks. It is moving heavy loads in all directions.

I'm thinking you'd need inclinometers.

No. Accelerometers (3 axis) are what are inside a smartphone and it knows up. After all gravity is an acceleration. Remember your general relativity.

Yep.
But would the accelerometers in a car be sensitive enough to be effective on a slight slope (considering they have to deal with considerable vibration in general operation)?
I guess it would depends how good the software is.

Two other things just came to mind:

GPS map databse which may have altitude information.

How is the software to know there is a curb? Wheels turn a different direction.


Don't count on GPS. It is good to maybe + or - 20 meters. Your moving map looks good because the software clicks you to the nearest road. Watch it when you drive past a shallow Y in the road, it can get tricked and show you on the wrong branch for a few seconds.

Car accelerometers I'm familiar with sense horizontal plane accelerations, for anti-skid braking and such. Nothing showing vertical offset. The parking assist sensors look for other cars, not curbs.

I don't think anyone I know (except the penny pincher who drives a stick for the better gas mileage) uses a parking brake as routine.
____________

I drive manual transmissions because they are more fun to drive.


Me too. Always use the manual parking brake on the manual shift car. Never use it on the automatic SUV that the wife drives. Modern automatic transmission parking brakes are just as reliable and functional as the manual brake. Manual brakes, on some cars, have a problem in this country of parts of the moving mechanism being exposed to ice and snow. End result can be the brake not set when you think it is, or not released when you think it is. The Park setting on the auto transmission is all enclosed, and not subject to weather issues.

Regarding turning the wheels to the curb, do cars that have automatic parallel parking do that when they finish?


They would need to know if they were facing uphill or downhill, don't think current cars have a sensor for that.

I think you are right David, the one in the middle is a slug, not a calf.

An interesting yard shifter consist from Thunder Bay, two cows and one calf. And another reminder that not all North American trains are grey.

When will people learn NOT to open "phishy" emails????
Companies paid more than $3.1B to fake-CEO email scams

Email scammers, often pretending to be CEOs, have duped businesses into giving away at least $3.1 billion, according to new data from the FBI.



I spent several years supporting the legal department of a major multi-national, and I was amazed at how many times employees fell for mail and e-mail scams. Their job was to process invoices as fast as possible, so if they received something that remotely resembled an invoice they would cut a cheque. No time, and no motivation, to think about it. I put together a half day training course for these people, that we figure saved $10,000 plus in the first year. Most of the scams were a few hundred bucks or less, but they came in daily.

LSM and I saw a pelican over the river when we were coming back from
Edmonton the other day. There are a lot more hunting birds around this
year. I saw a cardinal a couple of years back, and I was hoping it was
warm enough this year for a repeat showing. It is even better than that,
the cycle won't be complete for another two years so there is lots better
to come in animal numbers alone.



We have had steadily increasing numbers of cardinals in the yard over the last few years. There are at least two nesting pairs this year, and their offspring are starting to show up at the feeders. I read somewhere that the average cardinal never travels more than a few kilometres from where it was born, so it make take some time for them to penetrate into central Alberta.

From the photo, the incident should have been survivable to any passengers. Train is upright, coach volumes intact, no objects penetrating occupied areas. The alternative might have been to allow the train to drive on into annother occupied train, or an occupied platform, or into structure that would penetrate the coaches. De-railing is probably the lesser of many evils.

The REAL way to prevent this accident is to not drive through red lights.

Grant wins. Over to you. It is for fletching, or placing the feathers on the back end of the shaft. Or as some engineers would call it, the anti-pointy end.

Thanks for the win. We had a similar one awhile back, here is a modern one. Slightly photoshopped to remove obvious clues.

I forget the name, but don't they use big discs like this when tuning drums?

Don't let the fore ground fool you, the photo was taken on the Pacific coast in 1986, on a man made point leading out to a massive coal sea port facility.
When I was flying around that area regularly in the late 1970s it was a treat to watch these unit trains. They would unload, and switch engines, without stopping. They then ran back to the coal mines up in the mountains. The coal would move on to Japan, China or South Korea. Canada smokes up the world. These are SD40s, all looking somewhat shiny and new.

I have noticed over the last few years that both CN and CP are taking better care of their older equipment. You see old equipment like this, but you don't see old rusty, dirty equipment with the paint flaking off very much any more.

The smaller Canadian lines are another matter, however. This is Ontario Northland from last fall, at Thunder Bay.

For all you Californians who wonder where your margarine comes from. A train load of canola seed out of Saskatchewan, bound for the BNSF at Vancouver and then on to California. Canada feeds the world.

Posted 12 May 2016 by Profile Bill Walker
Just junked about 20 or so of my parents 78s, with some sadness. They had a much larger collection, but several moves wore it down. I looked into selling them, but there are very few collectable 78s these days, and my parents tastes didn't measure up. The few American pop recordings they had (like a teenage Doris Day) have so flooded the market that several web sites that buy and sell 78s have them on their list of "don't bother" artists.

My father had a lot of bag pipe music, and a few, from one particular label, were slightly collectable. If I paid $4 each to ship them to the UK, a dealer there would pay me $3 for each of them.

I looked into adding a 78 player to the sound system, but we are trying to downsize now (empty nesters) and I just couldn't justify the money or the space to play 20 albums. And I collect enough junk already, didn't want to start buying more 78s. I had trimmed my LP collection down to about 400, and then discovered some local places that sell old jazz LPs, and that number is creeping up.;)
