Part 2 is: Locomotive Company's Largest Operating Steam Locomotive passed through Sibley Iowa today, Oct 1, 2008 "Challenger" (No.3985) is on a 1,750 mile, 5 state tour that will end back in St. Paul Minnesota, where it began 16 days ago. Oil burning locomotives in the steam era mainly used "Bunker C" fuel oil. The company's purpose is to address the need for experienced, responsible, and dedicated management of … https://en.wikibooks.org/w/index.php?title=Steam_Locomotive_Operation&oldid=3693232. Learn more. There are no references to currently operating fireless locomotives found by this author. The reversing lever, or "Johnson Bar", does more than simply provide the reverse function of … 1 Though the engines varied in size and complexity, their fundamental operation remained essentially as illustrated here. That part of the boiler enclosing the firebox is known as the outer casing or shell. Fuel (originally wood or coal, and then later oil) is fed into the firebox where the resulting hot gas enters boiler tubes, known as flues, which heat the surrounding water to form steam. The firebox corresponds in shape to the back end and sides of the outer casing or shell, a space being provided between the firebox sheets and those of the outer casing which provides for the firebox being surrounded by water. (2000). Wonderful deep dive into step-by-step steam locomotive operation. Is restoring a steam locomotive to operation wasteful? You consent to our cookies if you continue to use our website. Alternatives include Number 4 fuel oil, kerosene or diesel oil (and sometimes a mixture of diesel/kerosene), others employ used motor oil. There is no such thing as a one-size-fits all statement in this community. The firebox sheets and flues constitute what is known as the heating surface. and Goldfinch, A.J. This is Part 1. Regardless of the kind of oil used, most locomotives store the fuel in a tank on the tender. In the operation the steam yields up a portion of its heat and the greater part of its velocity, but it keeps a current of water flowing fast enough to overcome the static resistance at the check-valve. It's simply written for british locomotives, and the really divert from german engines by construction and operation. Locomotive Firemen will not operate locomotives unless under the direct supervision of a qualified Engineer. Built for the Union Pacific Railroad as one of twenty-five 4-8-8-4 ("Big Boy") steam locomotives ordered by the UP to haul heavy freight across the Continental Divide. If it's not, then it's not your place to tell someone whether it is or not. Dividing books into smaller sections can provide more focus and allow each one to do one thing well, which benefits everyone. The boiler should be cooled down before any attempt is made to refill it, because forcing cold water into the boiler when it is very hot produces sudden changes in temperature of the various parts of the sheets and sets up destructive strains. After the steam is generated in the boiler to 200lbs per square inch, it is found that the boiler has expanded nearly one inch, which demonstrates that the metal expands as heating takes place and that when the boiler cools the metal contracts. Union Pacific Challenger No. Steam Locomotive Q1 w/Volume Pot Operation Manual, Version 3.1 3/22 13 April 2006 Advanced Analog Features Starting the Locomotive Most HO DC power packs with a standard reversing switch4 are suitable for Analog operation. A plainspoken American engineer from Abraham Lincoln's Sangamon County and his fireman explain in detail what it was really like "in the day." Steam locomotives are classified using a system called Whyte Notation developed by Frederick Methvan Whyte, which has been in use since the early 20th century. Silent Santa Fe training film for beginning firemen and engineers.Probably dates from the 1930's. The hostler prepares an engine each day for service. When the valve opens the cylinder to release its steam exhaust, the steam escapes under a great deal of pressure and makes a "choo!" The oil tank is equipped with steam heat coils to heat the fuel before combustion. Including every single one is nearly impossible; the list is always … To illustrate: Temperature of the steam in a locomotive boiler at 190 psi is 383 degrees Fahrenheit (195 degrees Centigrade). The steam whistle, headlight, throttle, air brakes, reverse lever, and fireman are usually under the direct control of the engineer. Big Boy No. There are two approaches: fire tube and water tube. 4014. Of the 410,000 miles of charter train operation in 2012/13, 103,000 of this was steam hauled. The smoke box is formed by extending the cylindrical part of the boiler beyond the front flue sheet. When the crown sheet or firebox sheets are not covered with water, they become overheated very quickly with a hot fire in the firebox. Learn how to drive a steam locomotive using RailWorks train simulator.See also part 2 http://www.youtube.com/watch?v=200acchgjxk My answer (and I think the most accurate in any case) is that if it's your [group's] locomotive, you decide the answer. Fireless locomotives were tied to operating in an area where they could obtain water heated higher than the boiling point while a fire was undesirable for safety reasons. In addition to this heating surface, there is an additional, or superheater heating surface in many boilers, which superheats the steam after it leaves the boiler and while it is passing from the boiler to the cylinders. When an injector is operated, the water passing through the injector on its way to the boiler is heated from 160 to 200 degrees F (71 to 93 degrees C). They were replaced by explosion-proof diesel or electric locomotives. The soot can be cleaned by throwing sand into the combustion chamber, but this causes undesirable wear to the flues and any superheaters. In order to bring out clearly and simply the cause of destructive stresses, it should fully be understood that the contraction or expansion of a body of metal when changes of temperature occur is irresistible. We also share information about your use of our site with our social media, advertising and analytics partners who may combine it with other information that you’ve provided to them or that they’ve collected from your use of their services. The flues in a locomotive boiler are known as fire tubes, because the heat passes through them, while the arch tubes, of which there are usually four in each firebox are called "water tubes" because the fire is on the outside, and the water passes through them. The terms and procedures described here will enable a person to safely operate a 19th or 20th-century steam locomotive well into the future. All that is about to change as the restoration of #81 to operation is nearly done. This is also the temperature of the water at that steam pressure. That jacketing is quite apparent in the September, 1949 photo of #81 taken by Guy L. Dunscomb in the first photo. In other words, if by any means the severity of the strains is reduced even though their frequency be increased, the period between failures will be prolonged, the time between repairs and the life of fireboxes and boilers will be lengthened. The steam locomotive is relatively basic contraption. Weighs 1,200,000 pounds. Power Systems Engineer Ryan Dela shows us how to drive a steam loco. If for any reason water is not maintained over the crown sheet, and the sheet becomes overheated, the fire must be put out or deadened at once, and under no circumstances should cold water be forced into the boiler. Bunker C fuel oil is very thick and difficult to use without pre-heating. The combustion chamber for large locomotives was originally introduced for the purpose that its name implies, of providing increased firebox area for combustion purposes. (Bunker C is also known as Type 6 or Number 6. The 4-4-0 American can be given overwhelming credit, more than any other steam locomotive design before or since its development, for helping the United States flourish beginning in the latter half of the 19th century. The semi-wide shallow firebox which rests on top of the frames and extends to the outside edges of the frame rails, and the wide firebox type having a firebox wider than the frames and extending outside the frame rails on both sides, and resting on top of the frame rails, or expansion brackets which are secured to the top of the frames. The engineer is responsible for it's over the road upkeep, oiling and proper operation of the locomotive to be the most fuel-efficient and easy on the machinery. The extended wagon top type, therefore, allows more steam and water space, and gives superior performance in foaming water conditions. The engine shown is a … The boiler must be treated with care at all times, as it must withstand tremendous amounts of heat, pressure and vibration. Steam Locomotive Engine. This sort of engine would be typical in a steam locomotive. The following diagram shows the major components of a piston steam engine. This is accomplished through careful regulation of the fire, and by regular addition of water to the boiler. It explains where the "choo-choo" sound comes from. ) While some preserved steam locomotives of today (circa 2005) still use Bunker C, most have switched to various alternative fuels as Bunker C can be difficult to locate, transport, and store. A steam locomotive is a locomotive whose primary power source is a steam engine. The most common form of steam locomotive also contains a boiler to generate the steam … Operating water injector or water pump while the locomotive is standing causes more frequent and greater inequality of temperatures throughout the boiler and the development of more destructive stresses than any other cause. Fireless locomotives generally used a tank (in place of a boiler and firebox) filled with superheated water that flashed into steam as the pressure from working existing steam dropped the pressure (refer to pressure table above). You can help by splitting this big page into smaller ones. Up until the Second World War it had been on duty for the Reichsbahn Directorate of Erfurt in Thuringia. Firing involves caring for the boiler and making sure there is always sufficient steam for the engineer to use. The crown sheet is supported by what are called radial stays, reaching from the crown sheet to the exterior wrapper sheet. The high-pressure steam for a steam engine comes from a boiler.The boiler's job is to apply heat to water to create steam. The engineer controls the operation of the locomotive but the conductor controls the movement of the train, and both are responsible for its safe operation. This arrangement provides that all parts of the firebox, as well as the flues, are completely surrounded by water, and it also provides that when fuel is burned in the firebox, the heat will be transmitted by the flues and firebox plates to the water; the unused gasses and smoke having free passage from the firebox through the flues to the smokebox and smokestack. Creative Commons Attribution-ShareAlike License. Wood burning locomotives fell into disfavour in the United States once expansion into the western plain states began, chiefly because of the generally lower amount of thermal energy wood locomotives offered from the fuel, and the scarcity of forests in the plains states. After the Second World War the locomotive carried passengers and freight in Saxony until the 1970s. The last steam locomotive built for Union Pacific, it was delivered in 1944 and is still in operation today. 3985 was designed by Union Pacific and built in 1943 by the American Locomotive Company. -A quick reference to Water boiling point (Not Steam Temp) at different pressures- The boiling point of water raises 3 degrees F per each pound of square inch pressure added. The front or cylindrical part of the boiler encloses the flues which are secured at the front to the front flue sheet and at the back to the inner or firebox flue sheet. The boiler shell is provided with a steam dome on top of the shell which forms a chamber where steam may collect and free itself from the water in the boiler before passing through the throttle valve to the cylinders. In the locomotive boiler, a large number of small flues are provided instead of a few large flues, in order that the heat and gasses passing from the firebox to the smokebox will be split up and come into contact with a larger flue surface. The prevention of destructive strains and stresses, or reducing their amplitude should interest all who have to do with the upkeep of the locomotive. This was traditionally the starting point for a person coming onto the engine crew. The small flue can be made of thinner material, which permits the heat to be more easily transmitted to the water which surrounds the flues. +1 PSI over sea level it will raise the boiling point 3 degrees F, to 215 degrees F (1.7 deg C, to 101.7 deg C). She will receive the green boiler jacketing that was used by the NN on its steam locomotives for many years. The fireman must control the amount of steam, oil, and air in the combustion chamber to produce the most efficient fire to boil the water. The engineer controls the operation of the locomotive but the conductor controls the movement of the train, and both are responsible for its safe operation. Not a "romance of the rails" film. The effect of this is the "Choo..... choo.... choo... choo choo-choo-choo" that we hear when it starts moving. Turn the front headlight on - above you on the ceiling, there will be a large, flat, half-round … There are three common designs of fireboxes in general use. Comparing the flue heating area with that of the area of the firebox plates shows that the plate heating surface equals only 5% of the flue heating surface, but the firebox heating surface generates about 40% of the steam. In the extended wagon top type of locomotive boiler, the back part, or outer shell, is considerably larger in diameter than the front section, or cylindrical part; while the straight type of boiler has the outer shell and cylindrical part of practically the same diameter. From Wikibooks, open books for an open world, Effects of Heating, Cooling, and Low Water. This is done to keep the oil viscosity such that the oil can flow freely to the combustion chamber. It is worthy to note that under some circumstances, the fireman can cause a series of hollow booms or small explosions though misadjustment of the fire. It will be noted that the boiler is divided into sections. A common delivery temperature of the water forced through an injector is 160 degrees Fahr. This difference of weight makes it clear why the cooler and heavier water seeks the lower levels and displaces the hotter, lighter water. A large number of small tubes also provides for the heat is more evenly distributed through the boiler shell water space. The fire in an oil-burning locomotive is controlled with two valves: The fuel valve, which controls the flow of oil to the atomizer, and the atomizer valve, which controls the steam to force the oil into small droplets for burning. 4014 is the world's largest operating steam locomotive. Additionally, Hostler's service locomotives with fuel and water, sand and lubricants and assure that all required tools and flagging equipment are provided on the locomotive. All advanced operations are easily programmed using your standard HO power pack. Cost to build US$ 265,000 in 1941, equivalent to $4,606,324 in 2019 The Union Pacific Big Boy is a type of simple articulated 4-8-8-4 steam locomotive manufactured by … It is one of 105 Challengers built for Union Pacific between 1936 and 1943 and is the largest and most powerful operating steam locomotive today. The steam … It is certain to find relief in some direction, either by self-destruction or destroying the obstacle opposing its movement. Weird & Wacky, Copyright © 2021 HowStuffWorks, a division of InfoSpace Holdings, LLC, a System1 Company.
