Steam Locomotive Reversing
At the time of steam?
As freight tonnage with high steam Locomotives crest of the hill "How they have with their brakes? [Considering there was no such thing "?] Dynamic Brakes Was it possible to put [Steam Engines] running back to act as a brake? The Trains used to transport the ass! And the braking system was "pressure = brakes. "No pressure Brake = off ". Example: Big Boy Ridge Sherman Hill with 100 freight cars of reefer then down quality with this huge burden. How was the engine used in braking it? You are right. When the Big Boys come, braking systems have been upgraded to the pressure "off = "= No pressure there. I should have known. Fantastic answers here. I'm so glad some of you older ones are still there to tell what kind of things.
Firstly, you're wrong about air brakes. The Westinghouse system is in use on all U.S. railroads in 1880 or more. Thus, the method has been to reduce the pressure in the Train to apply the brakes, as it is now. Second (and I'm surprised some people who do not seem to know this OD) of the Steam Locomotives have a form of dynamic braking. There excessive steam pressure in the pipes empty as the Locomotive. Later "superpower" steam locomotives was pressure "return" evaluate the engineer can use to set the threshold for optimal performance. But in general, the pressure is higher when the threshold is too late, when the reverse lever is held too far forward as the engine accelerates. Thus the engineer can obtain effects Braking by advancing the reverse order to use pressure as a retarding force. It is much like modern electric dynamic braking in that it creates more "drag" effect a parking brake "effect". Like the dynamic brake a diesel-electric locomotive can not stop a train, then the threshold of the advance "the effect can not stop, but only to delay a train. And it has a limited effect on a very heavy train. In the era of steam, it was much more common than it is today for the crew to stop the train at the top of the hill and lower the restraint to keep the brakes partially applied cars back about the first third of the train. This helped to keep the process of acceleration of many on the slope. Then you must stop again at the bottom of the hill turn restraint so that the train can reach a normal speed on the flat. I on a log of my great uncles who worked on the Santa Fe in the 1930s and 40s. He walked a train, a night to turn up the reservoir when he heard an animal running towards him. He jumped on the scale of the nearest box car, and barely missed being struck by a nine foot grizzly bear. As It tells the story, the bear was one of his boots, but he kept his foot that was it! So it was a combination of brakes air, imitating the kind of dynamic brake "against the pressure in the Steam Locomotive, and sensible, prudent practice by train crews. And clearly keeping grizzly!
