erie triplex tractive effort AXIA

Tractive Effort " Tractive effort " (TE) is the force applied by a locomotive for moving itself and a train. All six cylinders on these locomotives were the same size. Tourcoing (French: ; Dutch: Toerkonje [turknj]; West Flemish: Terkoeje; Picard: Tourco) is a city in northern France on the Belgian border.It is designated municipally as a commune within the department of Nord. The purpose of the Xa was to push heavy trains over steep inclines, requiring high tractive effort, but low speed, over short distances. The Triplex arrangement of three engine sets had . When the train is moving on a level track, then the acceleration due to gravity will be zero. So T equals approximately 39,193lbs. 2915-2934. I never quite understood the difference, I read somewhere on the forum that tractive effort is somehow linked with the weight of the train? However these locomotives, with their rather unique design, proved to be rather ineffective. tractive effort noun Definition of tractive effort : the force in pounds exerted by powered equipment (as a locomotive) as measured for statistical purposes at the rim of the driving wheels Love words? With a 30 m2 terrace, this apartment gives you access to the comforts you need for a pleasant stay in To. The first, shown above, is one the 3 Erie "triplexi", the "MATT SHAY" (#5014). Tractive effort: Factor of adh. They were built in 1914 and out of service by 1927. The ruling grade on thatsystem is 1 per cent., and there are manyof these grades. Tractive force: 160,000 lbs Wheel diameter: 5' 3" Firebox length: 13' 6'' Grate area: 90 sq ft: Street mechanical stoker 53-element Schmidt superheater Baker valvegear Union Pacific Big Boy 7. "Steam locomotives are some of the most powerful. One prototype was prepared for testing; two more followed not quite two years later. The firebox was almost the same size as the small boiler! An F7 is moving at 10.2mph, and is in RUN2. P = 28 kN * 60 km/h = 28 kN * 16.66 m/s = 466 kW. Unfortunately, the Matt H Shay's firebox was too small, being only 90 square feet. The Erie's test triplex #5014 was named Matt H Shay. A dynometer car registered a draw bar pull of 130,000 lbs. That was the idea anyway, but the reality of the situation is that these engines are very difficult to build. They worked well in pusher service, but could not keep up a full head of steam for road service. Tractive force or tractive effort or traction is the force applied between the tire and road surface to move a car or any vehicle for that matter. The Dutch class 5000 was originally conceived by the War Department in the UK about halfway WW2. middle, and the rear set mounted under the tender. First, we calculate the tractive effort required to simply move the train. New! The maximum permissible traction force that can be applied to the wheels is governed by two things: the weight of the vehicle and the adhesion coefficient between the tire and the road surface. It was so successful on the Erie's tricky Susquehanna route that the railroad ordered two more Triplexes in 1916. Not much, but they fit the bill for slow coal drags. The diameter of the driving wheels is 4 ft, and the boiler pressure 180 lb per sq in. There is a charcoal sketcth in "The Iron Horse" by Comstock, but it looks like it came from the photo that's already been posted. The four-axle unit has a continuous tractive effort rating of 52,500 lbs at about 9 MPH, while the six-axle unit has a rating of 78,750 lbs at about 5 MPH. Inevitably any such locomotive will be articulated. On March 1, 2012, Norfolk Southern announced that it would be honoring its predecessor railroads by painting 18 new locomotives in heritage paint schemes. The Erie triplexes (there were eventually three) operated between 1914 and 1927, mostly as pushers on the Gulf Summit gade east of Susquehanna, Pa. Class 640A 4-Cylinder Fireless Shunting Locomotive (1998) The quest to find a replacement for the ageing class 520A shunters gave rise to various designs, including the bizarre machine shown here, which was another creation of the RSR design staff in their "spare time". Physics Professor PhD (1969-present) Author has 13K answers and 31.8M answer views 1 y Triplexes produced huge amounts of tractive effort (80 tons or over 700 kilo-newtons). 6,844 posts. "Hauling capacity" leaves some margin and we might think of it as "working load." Note steam exhaust pipe at rear. Tractive effort on driven wheel Solution STEP 0: Pre-Calculation Summary Formula Used Tractive Effort on Train = (Gear ratio of transmission*Gear ratio of final drive* (Efficiency of Driveline/100)*Torque Output from Powerplant)/Effective Radius of Wheel Ft = (ig*io* (t(%)/100)*Tp)/rd This formula uses 6 Variables Variables Used Find the tractive effort. Located to the north-northeast of Lille, adjacent to Roubaix, Tourcoing is the chef-lieu of two cantons and the fourth largest city in the French region of Hauts-de-France . They were an attempt of the locomotive designers to put as much tractive effort as possible into one locomotive. There were 3 of them. Truly the most powerful steam locomotive ever created. Find this Pin and more on Erie Triplex by FransV. In most cases, maximum tractive effort is developed at low speed and may be the same as the starting tractive effort. The idea was basically very simple: use the weight of the tender for traction purposes by adding a third set of drivers.

The erie machines were used on the Susquehanna incline, A test train of 250 load wagons total trailing weight 16,025 tons achieved a speed of 13.5 mph, pushers were used to start the train to avoid starining the coupler. The result, conceived and patented by Baldwin's George R. Henderson, was a sort-of-Mallet, sort-of-tank articulated locomotive. The Triplex was engineered to haul 640 fifty-ton cars in a train almost five miles long. should i just make 1 video every month with 10 custom whistles? An F7 is moving at 40mph, and is in RUN6. It even has 66,000 more pounds of effort then the almighty Allegheny. T = 2650 0.72 ( 1500 2 8) 16.41531. Any help is greatly appreciated KSmiley Side question: what a train with ridiculously high power rating and really low tractive effort would be like? how to sell a dog on petfinder; what causes sediment in tap water; Newsletters; 2017 tundra maintenance schedule; can you claim out of date scratch cards The tractive effort required can be defined or given in two situations, one is in level track and the other in inclined track. The goal of the design was to put the maximum tractive effort into a helper engine. The steamer offered a mesmerizing level of tractive effort for the time that was greater than 176,000 pounds. Stories are told that 5014 ran out of steam on Gulf Summit grade, and the train would have to stop in order for the . Like the same railroad's large articulated electrics and the Erie Railroad 2-8-8-8-2s, it was nicknamed "Triplex". Their slick design, tremendous structure,and mind-boggling hauling power make them truly incredible machines. THE ERIE RAILROAD TRIPLEX: 1914 Above: The Matt H Shay, a triplex used for heavy freight haulage on the Erie RR. In general the so-called Austerity classes were conceived to serve the war effort with a minimum of resources in terms of production time, materials used and maintenance effort. But the couplers and draft gear of the early twentieth century could not have handled such a load, so the 2-8-8-8-2 was used as a pusher and never put to a full test. Each of the locomotives would be painted in a scheme to closely match those previously used by the predecessor roads. Most people would be surprised to learn that the tractive effort of a Triplex is a astronomical 176,256 pounds! The middle set was operated at high pressure, and exhausted to the front and rear sets, both of which operated at low pressure.
