railfancwb Posted November 13, 2019 Share Posted November 13, 2019 I still see motor vehicles running the tracks occasionally. It's cool!Was at the Walmart in Tullahoma TN recently and parked nose to nose with a seriously large pickup with the railroad wheels front and rear. Was a truck belonging to the Sperry people who cruise track using magnetic and other miracle tech to check for hidden flaws in the rails.

Sent from my iPhone using Tapatalk When I started at Sperry Rand Univac, it was primarily all about Magnetics. We made the Navy fleet standard fire control computer and it's memory was magnetic thin films. So our research department delved into magnetics on both a Microscopic and Macroscopic level. While I was there we did look into rail flaw analysis on an experimental level using Magnetic and acoustic fields to produce secondary reflections related to flaws. It's an absolutely fascinating field to work in. I have a few patents in various applied Magnetics applications. We even utilized magneto-optics, where an optical material could manipulate light. I'm pleased to hear that these studies contributed to a functioning sysem. 2 Link to comment Share on other sites More sharing options...

When you destroy in terms of square miles, you don't need to chase someone. In the process of removing some from life, you simply removed all to ensure your target was eliminated. Nuclear Depth Charges were based on that. Close is good enough. 1 Link to comment Share on other sites More sharing options...

Nuclear torpedoes were very accurate though and in terms of “nuclear pulse doctrine” we had in Germany, the time on target was more important than pinpoint accuracy to reduce cross platform detonations . 1 1 Link to comment Share on other sites More sharing options...

If it eliminated the target it was 100% accurate, so it's relative. The guidance may be precise but at some point it's immaterial. 2 Link to comment Share on other sites More sharing options...
tous Posted November 13, 2019 Share Posted November 13, 2019 That is why I preferred to serve on the small,, fast ships rather than those the size of an airport that actually were airports that would be the number one target of the opposing force. At the outer edges of the fleet, we would have a few milliseconds longer to say, Oh, crap. 1 1 Link to comment Share on other sites More sharing options...

Sent from my iPhone using Tapatalk From the amount of rust on the rail and the condition of the ties I would say that this particular stretch is abandoned but you point is well taken, I have seen more than one taking pic on or next to the tracks. Some want the train in the picture. i have seen professional photogs out at remote crossings getting Senior Pictures. . 1 Link to comment Share on other sites More sharing options...

I used to tell people that the value of a ship like mine was so low that it wasn't worth a missile or a shell. Without support at sea we couldn't last more than a few weeks, a month at best. We had 1911's and Thompsons to fight back with. 2 Link to comment Share on other sites More sharing options...
Dric902 Posted November 24, 2019 Share Posted November 24, 2019 Omaha-based Union Pacific has been ordered by a federal judge to reinstate an engineer who replaced the “ch” in “choo-choo.” Matthew Lebsack, while doing his duty, did his… Well, during a stop on November 20th, 2016, rather than utilizing a restroom facility, he defecated on a section connecting a locomotive to a boxcar. Talk about a gravy train. Additionally, Matthew admitted in court to having thrown soiled tissues out the window and raising his middle finger at the rail-riding vehicle’s security camera According to the lawsuit, he also told his manager he’d left a “present” for his co-workers. Great guy. He can’t help it if he puts the “loco” in “locomotive.” As perFox News: Lebsack later blamed the incident on physical and mental issues. The company terminated him, citing a rule prohibiting conduct that is “negligent, insubordinate, dishonest, immoral, quarrelsome or discourteous.” In December, the arbitration board ruled the termination was excessive and said the railroad giant should require Lebsack to undergo a medical and psychological evaluation with the option to discipline him if he’s found to not be fit for duty, according to the [Lincoln Journal Star]. Union Pacific filed a lawsuit defending its right to fire him. U.S. District Court Judge Brian Buescher upholds the arbitration board’s ruling — Union Pacific failed to prove the board overstepped its bounds in making the decision. . 2 Link to comment Share on other sites More sharing options...

This one is from sliding Thanks. I figured as much, but no one comments about the wheel, just the rail. People forget that Friction is a function of the force normal to the track, and it's not hard to generate tremendous heat with tremendous weight, and extremely small contact patch. 3 Link to comment Share on other sites More sharing options...
