The vast majority of these were inherited from its four constituent companies, the "Big Four".In addition, BR built 2,537 steam locomotives in the period 1948–1960, 1,538 to pre-nationalisation designs … I would like to think that has gotten better during the last century. No, not with diesels coming anyway. Nuclear power is often actually steam turbines heated by fissionable material. Following in Porta’s footsteps and a colleague of David Wardale’s, Shaun McMahon, CSR Director of Engineering, is an internationally-renowned modern steam locomotive mechanical engineer. But somehow, they are either gone, or reduced to niche roles). Scale/Era: HO Modern. He thought that the reason the Chinese were even able to burn this coal at all is that had something akin to a "slag tap" combustion system going -- they had enough molten clinker on the firebed that when they stoked this coal, it would stick to that slag and not get carried off. This mechanical honesty has long captivated onlookers and invited study, but many still wonder just how it all … The new release from Bachmann’s Spectrum line includes SoundTraxx Digital Command Control (DCC) and sound, and features boilers, domes, and other details specific to the prototype road names. Until after World War II, the reciprocating steam engine locomotive ruled supreme. He thought that electric drives will "replace everything" and I tried to educate him about the need for quill or even Cardan shaft mechanical drives, from the electric motor, to reduce track impact in high-speed trains. The German innovation's description causes me to ponder: Did they reinvent the Camelback, the Mother Hubbard, countless Anthracite burners?....rarely called saddlebacks....that isolated the fireman at the rear and could have been designed to put the cab further forward. At least with an electric motor, you just need to supply a pair of wires, and if those wires are thick enough, which is usually not a limiting factor, those wires can bend as needed around corners. Steam engines can take up to 10 hours to raise steam from a cold start, The weight of water,fuel etc. steam power is a main driver in some countries, e.g. If diesel-electric engines become nonviable, this will not bring back steam engines. A spirited gray horse was pitted against a tiny steam locomotive, the Tom Thumb. There actually was a "jet train" once, but not quite what you are describing: What would a steam locomotive look like if steam power became yet again the main type used in rail transportation? I would expect the driver to be at the front because (a) most of the business of fueling the train would be handled by automated machines, (b) the controls would be electronic rather than mechanical and could be operated from a remote cabin, and (c) the front offers better forward visibility and safety. My suspicion is that if all else worked as expected, the violently explosive nature of pre-ground coal dust, and its propensity to stick or 'bridge' with even small levels of humidity, would be reasons against use of the idea. This obviously didn't happen in real life, so in all what you wrote there is no point of divergence. Lately, natural gas seems to be the answer. Why the two connected routers via PPP doesn't use ARP but ethernet use ARP? Fluids are easier to handle. Technology should be the same as we have now. Also, as someone who rode electric trains from Moscow to Vladivostok, I scoff at your "vast expanses". The machine was created out of a 100-ton hydraulic press. http://ultimaterestorations.com See how the boiler of a steam locomotive works. 844's boiler testing. I upvoted it for the first one - the Mallard still holds the world speed record for steam locomotives! The hundreds of thousands who have fallen in love with the Big Boy are awestruck much like those in the 1940s who first witnessed this behemoth locomotive. Also there is no more efficient way to distributing energy than as electricity. If I understand the setup correctly, the coal supply runs pressurized. Painting: Robin Barnes. Natural gas has a very low heat content both by mass and by volume. Mainly constructed from solid brass sheet and tube with a black finish, all the moving mechanical parts are made of … How would people power vehicles on a planet with no fossil fuels (like Mars)? a steam locomotive is a way to be transportated or a way for transportation. Here is a great Lionel 18008 O Gauge Disneyland Railroad 35th Anniversary Steam Locomotive and Tender from 1990. With modern automated equipment the fireman can monitor the firebox and operate the stoker remotely from the front of the locomotive. Only 30% (20% in the case of biomass) of the combustion air passes as primary air through the grate, thus leading to an almost negligible particle entrainment. It only takes a minute to sign up. Check the photos for a detailed look at this item. In the early diesel/electric locomotives there are throttles which resemble steering wheels, while steam locomotives have handles which resemble levers for various vintage machines and devices. Porta describes his Gas Producer Combustion System (GPCS) in the following manner: “It essentially consists in transforming the firebed into a gas producer by making it very thick. Should integration tests test business logic? But how could we improve them? It was brought to Canada to help build the Trent canal. Part of the story is very large size; part of the story is long-period stable operation at baseline load that requires little if any turndown from design conditions; part of the story is lots and lots of packaging space for aftertreatment, air preheat and economizer operation, etc. Assume in the very near future almost all rail transportation would return to steam-powered locomotives. If you are hellbent on creating steam engines again, they will not be the stereotypical puffing chugga-chugga-chugga kind that we are used to, but instead just versions of the diesel-electric kind, where the steam engine drives a generator that in turn drives electrical motors on the wheels. I happen to believe that a nonsynchronous method of conjugation is preferable (and have described it to a certain MEGO level) but it is beginning to appear as if conventional methods can provide most of the benefits of duplex conjugation without the, er, actual conjugation. His take was that it was much more efficient with greatly (reduced) carryover when he got it to work, but getting it to work depended greatly on just what coal you were burning as well as educating the crews on the correct procedures, that included such things counter to their training of piling on a thick firebed and leaving the firedoors at least partly open at all times to get enough secondary combustion air into the firebox. Third, we still need to account for the behavior of the atmospheric nitrogen; in particular, we can't heat it excessively or it will give us NOx pollution even at fractional-atmospheric ambient pressure. In North America and Europe, and in much of the rest of the world, it has since been replaced by the diesel-electric locomotive. Or some mad scientist might team up with a sane engineer and perfect a little box that eats used cat litter (or anything else equally worthless) and produces 650VDC, ready to feed to the AC drive controllers and the skewed squirrel cage traction motors. Work is also underway fitting airbrakes to the locomotive along with the mainline safty electronics the black box data recorder, GSMR radio system and the Train Warning Protection System for todays modern mainline running on Network Rail. Source: wikimedia.org. Check the photos for a detailed look at this item. Per Wardale's Garratt proposals, that water tank would be an emergency water reserve kept filled to maintain traction, and water would be drawn down from a trailing tank car as done with the GMA/M. There is also some light edge wear. Whatever the reason, steam locomotives are coming back. Availability: Ships within 1 Business Day!. It idled and when you needed it, you just hit the levers and off it went. a battery — between the generator and the electrical drive-engines. 24″ Gauge Mining & Tunneling Locomotives. Steam power would be steam-electric Diesel trains don't run diesel engines coupled to gearboxes coupled to the wheels. Modern ones will use a diese... President Hall felt that the NC “should ‘doll’ the new engines up so as to make them look modern,” and he was agreeably impressed by an all- streamlined proposal which Alco furnished (apparently a design similar to N&W’s J). There is a difference that I have remarked on the pilot (AKA cowcatcher) of older (ca. The power you wish to generate on-board the train will not be done so, but instead at a power plant. I also have a grim suspicion that Porta's 'cyclonic' combustion chamber arrangement actually has flow patterns different from those he expects, especially at high turndown and during flow-transition between low and high turndown. As I commented on another answer, my second thought about this question was a steam-electric locomotive. Secondly, there may be some modular solution for more efficient refueling (rather than just 'pouring coal in from the top'). Here is a Lionel 18009 New York Central 4-8-2 L-3 Mohawk Steam Locomotive from 1990. Form follows function. This combination minimizes back pressure and ensures a blast velocity through the stack that can exceed Mach 1. Some of the issues could actually be resolved through the use of supercritical CO2 as the medium of energy transfer other than water. The main problems I can see with steam over electric is power and speed. Do you think an RTG that produces enough power to "push a train" is feasible? Assume no economic or societal collapse, or at least not a too large one. Check the photos for a more detailed look at this item. Is it plausible that a country developed steam engines before gunpowder? Here is an O Modern C&O Legacy Allegheny Steam Locomotive and tender from Lionel. Found inside – Page 127However, steam die-hards may breathe again, for in no way, ... It is good that examples of modern BR traction should stand beside their steam counterparts ... You still need a crew member to operate the stoker and keep an eye on the boiler pressure and water levels and anticipate changes in steam demand by seeing what the engine driver is up to, so you don't clog the fire, allow thin spots instead to develop, waste steam by popping the safety valves when the pressure limit is reached, stall out on the road by letting the pressure drop, and yes, kill yourself and your driver by letting the water-wall water level drop that the firebox overheats and blows everything up in a water-flashing-to-steam explosion. Water consumption of steam locomotives was not a primary reason for the transition to Diesel electric. So they will be quite boring looking, and not the stylish art deco machines of the 1920s to 1940s. This major reduction in the volume and consequently speed of primary air being sucked through the fire greatly eliminates unburned fuel particle carryover and the sand-blasting effect on the inside of the boiler as compared to traditionally-fired steam locomotives. Overall condition is Like New. On the newer ones, you typically - nay, almost univerally - have a bona fide coupler, and the pilot will be relatively short. The technology was known in the steam age (they had cars back then!). It never got off the drawing board (see Sidebar). See this fine example from Canada. They also generate electrical power, but the screw is driven by a giant reduction gear. So the "gas producer" is not that you are turning the coal into gas to have a gas fuel. The minute you go to a divided drive of any kind, articulated locomotives are a simple version of the steam motor idea, things get really complicated really quickly. However, the engineer and fireman were separated, the firebox being in the back of the boiler by the tender. I've seen the artist's conception. So, what is the combustion system of a steam locomotive, and what difficulties does it have? Somehow I think that change, when it comes, will come quickly - and from an unexpected direction.
