We "joke" about the busload of nuns, or maybe a BMW full of plaintiff lawyers and plaintiff experts,
Almost all locomotives now have a "Track image recorder" like a dash camera with sound. .
324,000 eggs, hapless truck driver, and a really cold day.

Hmmmm... I "thought" trains worked the same way....
Nope.

I did day third...
I know what the revenue streams are. Intermodal is also a very high $$$ per train. Think priority UPS trains or "Z" trains.
I'm not going too far out on a limb here. I do have some "first hand" knowledge of this accident.
For a while they are.
If pressure on the brake line is lost, the brakes will engage as the 'triple valve' will direct air from a reservoir tank on each car to push on the pistons that actuate the brakes (a variant of the Westinghouse air brake). What holds the brake on is the pressure in that reservoir tank. As most pneumatic systems go, they dont hold pressure indefinitely so eventually the brakes will let loose, one car after the other.
If you want to park a train unattended and without a locomotive attached, the hand-brakes have to be set on a portion of the cars. On a flat surface, they may set 10%, on a grade they have to set 20% or 30% of the cars. Doing so is manual labor, the conductor or a brakeman has to walk the length of the train and crank the hand-brakes shut. On a 104 car coal or oil train, it is not a lot of fun.
Weilke's got it.

So, you've finally given up on the nuclear sub idea that could power a couple hundred homes?
They could easily produce enough hydrogen to power the beginnings of the fuel cell car industry while other infrastructure is under construction was my point since IT'S ALREADY PAID FOR!!! Get it yet? Don't waste what we've already spent trillions of dollars on, then pay billions more decommissioning perfectly good working equipment when it can be put to work. Wow, we're such a wasteful society. We just spent a **** load of money decommissioning a freshly refueled aircraft carrier.
Everybody wants to complain about government waste, but show a way to reduce waste and provide material to start a new industry and you **** all over it, **** you.

Thanks.
I've been away doing train stuff... A lot....
Hopefully I'll get back to Denver this year, so we can get together for dinner. I don't think I've gone a year without a Denver stop in quite a while, so it will probably happen. I just wanna stay out of Cheyenne until spring!
I hope you guys are staying warm. I've been away from work since 16 December, but back at it tomorrow, unless we get a crap ton of freezing rain. Left my Zamboni at the summer cottage.

Energy is energy...whether you generate electricity or hydrogen, the amount is the same...it's enough for a couple hundred houses, or maybe a thousand cars total.
Right, a few thousand cars, each, all easy to park in major metro areas to provide for a market that is waiting for the hydrogen to happen. We're also looking at retiring more nuclear aircraft carriers. It will take a few years for the market to expand beyond a few thousand cars as manufacturing gears up and people adopt the technology, just like any new technology. The energy development to meet a larger market will develop with the market. We already paid for all this energy, why do you think it would be better to pay more to waste it throwing it away? This is all stuff that is a large part of that national debt we always hear complaints about, yet you don't want to use it to pay back. New jobs, new industry, new low cost energy. Nah, **** that, lets just complain and drill for more high priced oil.

No, a few thousand cars for the fleet.
The energy that they run on is pretty skimpy in the grand scheme of things.
An Ohio class is 45 MW/hr, a Los Angelese is 26 MW/hr. A Tesla S uses 38kW/h for 100 miles. There are 40 Los Angeles class subs and 18 Ohios.
Please explain your math.
Hmmm..
Parking /anchoring used, obsolete nuclear powered war ships off the coast and tying their power output into the grid is a interesting concept...
Can you convert those 45 MW ,26 MW and 38 MW ratings into real life on shore powerplant outputs???

Pull the props, attach generators.

Fantastic...so you lose 50%-60% converting to electricity, then another 40% on top of that converting to Hydrogen, and another 30% converting back to electricity, and more again converting to movement.
Please, show your math, then we'll factor in the value of the water.
Yeah... But.....
Can a hull sit still in a body of water and not heat up the surrounding water when running at 100% output......
Greenies would have a stroke....

What would be the difference there or with the current power plants doing the same thing at even higher capacities?
Powerplants have built in cooling ponds designed to shed heat... A hull sitting still in the water will heat up the surrounding water tremendously.. Now, if they thought it through completely, they could anchor it is a harbor, heat the water and us it as a water park year round...

I don't see any around Turkey point, straight into the Biscayne Bay, same for others along rivers.

Uhh.... What are the miles of canals and channels that have been constructed that receive the output water?

Interesting, never have seen them. Oh well, the best thing to do with the excess heat is to dry algae and preheat salt water for more efficient desalinization.
There are numerous cooling ponds around Turkey Point... We used to swim in them back in the 70's...... Before the gators got thick and then the guards ran us off.......
Google Earth it and look to the west and south of the plant.....
Edit.... I noticed the previous post addressed this...

Ahh the weather is what it is. I'm whining more about it this year than usual but it happens.
Come visit in Spring and we'll go fly the 182.
The rest of this thread is hilarious. Guys who have no say in it, arguing over which of the non-starter technologies to build.
Nobody is going to build any of that stuff until it pays all the bribes necessary to the politicians to get government grants to do the initial development of the tech risk-free to the exec's wallets.
They're not all non-starters because the tech is bad. They're non-starters because there's no guarantee they'll pay for the six martini lunch and this year's golf club membership.

Is that because you have that long drive from out here in the sticks?
I don't think the weather has been nearly as bad this year as other years. I haven't gotten my snow shovel out once. Of course I don't shovel too much unless I can't pack it down with my car...

Ha. Nah. I like driving. Doesn't matter if it's good or bad weather really.
Agreed it's not bad. I found out last night the true use for a dually pickup is to pack the driveway snow down twice as fast.
One neighbor had his snowblower attachment on his John Deere tractor today and was clearing his driveway, but his driveway is surprisingly steep for out here, and frankly he likes playing with his toys. I just ran errands and packed it down on the way in and out. The tractor stands ready in the garage if needed. Heh.
I'm just personally more cold- sensitive this year than in the past. I used to run around in layers and a light jacket and no gloves or hat for most of the winter, but lately I'm a t-shirt, a long sleeve shirt or sweatshirt, the Carhartt jacket with the hood up and heavy boots to keep the feet warm. Not that much more dressed and not cold once suited up.
I can't tell if I'm just less tolerant to it because I have good cold weather gear available or if I just think snow is stupid. Heh.
But with that stuff on, as long as the wind isn't blowing, I'll still go outside for hours and shovel or plow or walk the dog or otherwise mess around.
I did wimp out on Saturday and take my Fleetguard oil filter and the 5W-40 Valvoline Blue Extreme over to Jiffy Lube and let them change the oil on the diesel, instead of freezing on a crawler under the truck in the 25F garage. I hovered a lot and asked if they'd write the date and mileage on the filter in Sharpie and even brought them a Sharpie just in case. (They had one.)
$24. For ten minutes of work and five minutes of prep. Sigh. Just typing that pains me. But I got to stand around and drink coffee and talk trucks with the counter guy instead of doing it myself on freezing concrete.
I didn't even let them touch the differentials other than to check quantity with the little dipsticks the aftermarket diff covers have. And I jokingly threatened pain if they opened the manual tranny fill hole, but I secretly wasn't joking. It's overfilled by almost a pint through the top as most of these manuals are since there's a problem with lubrication not reaching the rear bearing on hills. Open that full hole and that all comes out... Somewhere around 250,000-300,000 when you rebuild it, there's a notch in one of the separator rings that allows oil to flow properly to the rear after the rebuild. But for the next 150,000 miles it's overfull.
Air filter? Nope I'll take care of that. It's non-standard sized anyway. Washer fluid? Aww sure. Throw some in. It takes more than a gallon.
I chuckle when they check lights. Doesn't anyone ever do a walk around to check lights on their own anymore? Sigh.
