M = Mass of locomotive at the centre of gravity. Beale was highly impressed (motive power must not have been his strong suit). When designing the locomotive Lima had to make sure it kept the length The Virginian also purchased eight of its own 2-6-6-6s in The railroad had several of its now-famous locomotives on display, including its EL-C and EL-2B electrics (both visible in the background). Their success depends on humans utilization of them. This characteristic detail is somewhat mysterious, and is unfortunately . The AMC knew that C&O would buy anything it recommended and was willing to spend as much of C&O’s money as necessary to accomplish its goal.

Dear Mr. James R Black, the H8 did not have “low pressure cylinders”. Without a doubt, that single loco type/class/model pulled harder, went plenty fast enough to fill out the ton miles per train hour dance card, and obviously made more money for it’s owners than any other. The measured values of tractive effort are given in Table 3. And the truth is that at the weigh in of the Allegheny, a few shenanigans were undertaken to make sure it weighed more than a Big Boy. And Mr. Lehtola, you bet, DM&IR and NP’s Yellowstones were incredible engines, too bad the money isn’t there to get the Yellowstone running again. 1604 is a simple articulated locomotive.

It should be noted that Chessie was not the only buyer of the (Chesapeakes). I am sure they lost money on the beast. Greatest articulated loco’s ever built! The "Allegheny" locomotive series was considered one of the heaviest and most powerful American-built steam locomotives ever built. Many were pulled up in the 1970's and 1980's although others were removed long before that. Most yard switching applications seldom exceed about 30,000 pounds of tractive effort and speeds of 5 to 7 miles per hour. either one, or both, set of driving wheels pivots to better and more 2.6.2 Tractive Force and Adhesion It is the tractive force at the locomotive driving wheels (drivers) at the rail that starts In 1986, the No. And while Ed King may like eastern steam power(as I do) his comparisons are fact, not fiction. A very heavy price for Lima to pay for horsepower and engine weight bragging rights.

This newly revamped book features every steam locomotive built in the U.S., Mexico, and Canada since 1900. This is an essential guide that should be in the library of every railfan! Although I am not aware of any N&W boasts of a million miles per loco, 101 Y6’s reportedly averaged 6000 miles/month from 1942 to 1957, (last ones were retired 1959) which works out to (4x more) 108,000,000 miles, over a million miles per unit. Therefore the industrial locomotive will perform well with 500 to 600 horsepower. in this capacity except for occasionally moving a few heavy mail trains. The boiler sits on the leading frame and is attached to the second frame. The best thing about the UP, C&O and N&W super power steam is it gives us all something to chew on ’til we are dust w/o a definitive answer on who was best Points about tractive power comparing UP Big Boy’s 135k lbs at 0-35 mph to C&O Allegheny’s 110k lbs at 0-45 MPH, and that all manifest freights ran 40-50 mph tops, are key. then-in-development Big Boy. Folks, when you talk about who’s king of the rails, you are discussing gold & silver, plain & simple. ironic considering the Allegheny would rarely ever be used in such The issues at the scale house in Lima were that the H8 was too heavy, and Lima tried to hide this fact. 100,100.pounds @ 10.3 mph Tests on a 100 car train have indicated that this time may be as much as 9 minutes in the tender having an uneven truck setup, four axles on the rear and Home / Railroads & Locomotives / History / Big Boy versus Allegheny, The story of the Union Pacific and Chesapeake & Ohio locomotives that fought for 'most impressive steam locomotive' title. First we need enough power on the wheels and second enough weight to prevent the wheels from spinning. handle the stiff grades along its main line between Hinton, West Tom Stamey June 26, 2016 Reply. That is their prerogative, however distasteful, but to not change the engine number when converting to oil like every other railroad or preservation society is dishonest and deceitful, not to mention pushing it around with a repulsive diesel in tow.I suspect that it is because fuel oil causes many hot spots in the fire box and boiler which shortens engine life. Found inside"This book is an indispensable illustrated resource for railfans and families on road trips, filled with easy-to-find information on locomotives and rolling stock, such as railroad cars, coaches, and wagons"--Provided by publisher. This is a term used on the CNR to denote a locomotive's tractive effort as a percent. Beale worked as a senior manager through the Allegheny territory where Train resistance and tractive effort are both measurements of force (typically in pounds in North America) so we can simply overlay the curves How do we relate tractive effort curves to train resistance? Found inside – Page 75... coal drag toward Allegheny Summit on the old Chesapeake & Ohio at Tuckahoe, ... tractive effort and versatility, GE dieselelectric locomotives do more ... The information includes original numbers, serials, and order numbers. Think, for example, of the Berkshires of similar design that the C&O associated roads utilized. 2-6-6-6. A full third of her tremendous engine weight rests on her lead and trailing trucks – dead weight that must be forced into motion in situations like this. It is a must visit! h = Height at which tractive effort is exerted by the bogie on the locomotive body. I = Bogie wheel centre distance. The locomotive is made of diecast, which is sturdy and adds weight to the engine, thereby aiding the tractive effort. UP only had to hook on mile long trains to her and let her rip and rip they did, and in 2019 they will again. of its first ten Allegheny Types from Lima in December of 1941, numbed If higher quality fuel had been used, it might have been able to use less of it. Were the Nickel Plate engines better than the C&O’s? However, a comparison of drawbar pull curves of the Y6 and the UP 4000 shows that the Y’s large starting tractive effort advantage (made possible by simple operation of the low pressure cylinders) is gone once its speed reaches 8 miles per hour. It is calculated by the formula. The locomotive, an articulated design (meaning that Other Locomotive Forces# Traction Motor Quirks#. The D&RGW L-131 had 131,800 lbs of tractive effort not 140,093.

Y. , established in 1869 ; Pittsburg Locomotive Works , of Allegheny , Pa . - What were the usuable min. For a typical locomotive the friction coefficient is about 0.3 - this means the tractive effort of a locomotive weighing 180 ton can't exceed 0.3 X 180 ton = 48 ton ~ 480 kN. not operate faster than 35 mph. To identify the tractive effort in the rail-wheel-contact of a locomotive a coupling hook is used. In the main line train, tractive effort is caused by the locomotive, and in a suburban train, it is caused by motor coaches.The draw pull bar force is the horizontal force available . In 1986, the No. Considering Y’s weighed only 582k-611k lbs compared to BB @ 762k-772k, those numbers are incredible. Don’t see a reference to the 2-8-8-4 Yellowstone of DM&IR game.

Manufactured by Lima Locomotive in 1941, two examples of these monsters survive today; #1604 at the Baltimore & Ohio Railroad Museum and #1601 the Henry Ford Museum. (Thanks to Ed King's "Big Boy Or Big Mistake?" So the Allegheny did, indeed, beat the A’s horsepower figure. the '20s had a tonnage rating just 200 less than an Allegheny. As with "power", there are different methods of measuring tractive effort: So, as long as you’re content to limit your train speeds to 30 mph, the compound Y is a great choice. = Horsepower X (308) Speed (mph) Where 308 is 82% of 375 lb-miles per hour per hp. In a paper,2 presented before the A.S.M .E., December, as the method of 1932. On the simple expansion articulated locomotive, all cylinders receive steam at boiler pressure (high pressure steam). mighty articulated steam locomotives locomotive). For example, a 3000 hp locomotive will have approximately 74,000 lbs. Through vintage photographs, Bessemer and Lake Erie Railroad highlights the railroad passenger excursions to Conneaut Lake Park and the steam and diesel locomotives used on the well-maintained line. more than the Alleghenys’ 110,200 lbs. Found insideWe also discover that classical political economy has been so instrumental in guiding these strategies. The book leaves us to wonder how the same mechanisms are reproduced today. This critical question pervades the book. 3 Tractive Effort Tractive effort is defined as the turning force produced at the rails by the driving wheels. The 2-6-6-6 fared better hauling tonnage up through Ohio on C&O’s Russell (Ky.)-Toledo run, but because of a car limit imposed by the operating department, Chessie’s T-1 2-10-4s (probably Lima’s finest locomotive) of 1930 could do the same job much more economically. Tractive effort is the force required to haul a load. in accordance with the published tractive effort characteristics of the locomotive. A: About 58 mph. It was efficient at this job and was capable of high tonnage ratings. The 2-6-6-6 is today considered by many to be the ultimate expression of the Super-Power concept. Theforr-cylinder"balancedcompound, locomotive.Supplementtov.12ofthe Scienceofrailways.I9O4, HI 1904 Tractive Effort (lbs.) He bought eight more of them, plus five C&Ostyle 2-8-4s for fast freights. But for an additional 100 tons of engine weight and an extra $100,000 per engine and tender, shouldn’t it have? And Mr. Nation, you are a nitwit. The "Allegheny" locomotives were quite successful pulling slow coal drags through the mountains, but they could also travel as fast as 60 miles per hour pulling occasional passenger trains. Found inside – Page 69The parts of a locomotive tell many things about it. ... The Diesel's large number of powered axles, on the other hand, give it a "tractive effort" ... The onset of World War II produced two of railroading’s most impressive “bragging rights” locomotives – Chesapeake & Ohio’s Lima-built 2-6-6-6 and Union Pacific’s Alco Big Boy 4-8-8-4.
