Just out of idle curiosity that GE AC6000CW has a starting tractive effort at 188000 lbs while weighing at 423000 lbs, ES44AC has TE of 183000 lbs weighing at 432000 lbs, SD90MAC-H has TE of 200000 lbs weighing at only 415000 lbs. Evolution Series locomotive. Conrail was the first railroad to receive the SD80MAC in early 1996. Tractive effort 126,000 pounds-force (560,000 N ) The NRE 2GS36C-DE is a low-emissions six-axle diesel-electric road switcher locomotive built by National Railway Equipment Company. A total of 161 examples of this locomotive were built for two North American railroads: Conrail and Norfolk Southern Railway. Drawbar Horsepower: horsepower available to haul. AC traction for locomotives is a major improvement over the old DC systems. Models Currently, six different Evolution Series models have been produced for the North American market. ) A total of 2,366 cab-equipped lead A units and 1,483 cabless-booster or B units were built. "CTE" mode turns a C44AC into the equivalent of a Dash-9 in terms of maximum tractive effort, limiting it to 110,000 pounds maximum. Photo Date:. Overall dimensions for the Dash 8-40CM are 70 ft 8 in (21. This rethinking of locomotive design allows the N-ViroMotive to apply a new configuration to standard rail purposes for superior. 9 Traction diagram After the calculation of Tractive effort required and Tractive effort available are done and tabulated, the last. Registering takes only a few moments but gives you increased capabilities. Which brings the final designation to "C45ACCTE. As locomotive weight and friction coefficient determine tractive effort and horsepower determines speed I do understand the tonnage rating and the tonnage or tractive effort rating per powered axle. More power does not mean more load. I may release these mods. Listed below are the N scale items we are planning to produce. The N-ViroMotive is the first design innovation over the single engine prime mover, which was developed in the 1950s. Tractive Effort is the force needed to simply move the train. These locomotives have been ordered by Union Pacific Railroad (who refers to these locomotives as the C45ACCTE ), BNSF Railway , Norfolk Southern Railway , Kansas City Southern Railway , Kansas City Southern de Mexico , Ferromex , and Canadian Pacific. Another group of projects are the "heavy" units. That is why some locomotives that are less powerful than another class, still have a max higher tractive effort. Later Tier 3 models are rated at 4,500 horsepower (3,400 kW). For slopes, you will need an additional 100 Newton per percent of steepness. this improves tractive effort by as much as 40%. This software was carried on from their AC4400's and is now standard on Union Pacific ES44AC 's. ) due to having thick metal plating underneath the frame (reminiscent of CSX's "Phase 2" SD70MAC units), with the addition of having a radial truck or bogey model/style meant to give an additional amount of wheel adhesion, tractive effort. Obviously a great success due to fewer mowing parts, less parts to be kept in storage and less need for maintenance this new AC model has now gained a lot of ground. RailPictures. Today’s Topics • F=ma examples • Non-constant forces. Road Number 4659 These locos will be released November 2017 and will start shipping on or about 11-15-2017 The ES44ACs are here! Just in time to heat up the summer, we bring you the highly anticipated ES44ACs. Jan 7, 2019- (ET44AH). tractive effort diagram Gesamtwiderstand 1. Broadway Limited is excited to release its most modern diesel locomotive ever -- The GE ES44AC. CSX has some 200 units on or coming onto its roster, while Iowa Interstate ordered 14 units. Tractive Effort. The "H" in ES44AH stands for "heavy", which is in reference to a combination of subsystems that produce high levels of tractive effort at low speeds. , and the radius of the wheel (1/2 the diameter). I’m going to answer this question through the lens of the time. American Z Line 62404-1 Ferromex ES44AC Loco. The "H" in ES44AHstands for "high", which is in reference to a combination of subsystems that produce high levels of tractive effort at low speeds. Each locomotive weighs 432,000 pounds and provides a starting tractive effort of 183,000 pounds. CSX has modified some GE CW44AC and CW44AH units to heavy units by adding extra counterweights to the frame and in the nose of the unit shell and new computers to increase tractive effort at low speeds, they are 432,000 pounds. However, at higher speeds, when wheelslip is no longer an issue, the ES44C4 would behave in a similar fashion to the ES44AC, because tractive effort at higher speeds is dependent on horsepower. Title: BNSF 5759 : Description: Evolution power waiting to exit yard. The Evolution Series 4400HP DC Traction locomotive is part of GE Transportation Systems line of diesel locomotives that were built to meet the EPAs 2005 Tier 2 locomotive emissions standards. Tractive Effort. A for effort phrase. Better tractive effort? - TrainSim. They are rated at 157,000 lbf (700 kN) continuous tractive effort (191,000 lbf (850 kN) starting). ES44AH (C45AH) The "H" in ES44AH stands for "heavy", which is in reference to a combination of subsystems that produce high levels of tractive effort at low speeds. Gradeability for Automobiles www. CSX began receiving an order of 200 ES44AC's (referred to by CSX as the ES44AH) in December 2007. an older SD60 model. Advantages of AC traction motors include: * higher starting torque output and higher tractive effort. Photo Date:. I’m going to answer this question through the lens of the time. Tractive Force = Weight of Drivers x Coefficient of Adhesion. How GE got on track toward the smartest locomotives ever These sensor-packed locomotives compute some 150,000 data points per minute. Hence, due to the increasing popularity with said model, BNSF decided to replace their order of subsequent ES44AC's in favor of the newer, more reliable (in terms of weight distribution, tractive effort, and axle loading over the original model) and advanced ES44C4. a fm switcher dating from 11-1951, with the nifty cab roof overhang. [1] The first demonstration unit was released in August 2011 from NRE's Mount Vernon shops in Southern Illinois. They are rated at 157,000 lbf (700 kN) continuous tractive effort (191,000 lbf (850 kN) starting). Drawbar Horsepower: horsepower available to haul. ES44C4 - A1A-A1A trucked version (only 4 powered axles), so far only owned by BNSF Railway and Florida East Coast Railway. The Ability to Overcome Resistance-Starting, Grade, Wind, Curve, Rolling. As for the locomotives in the lead photo, CP SD40 5514 was built by GMD London in 1966. British Columbia-based Tractive Power has a unique solution: a compact (27-foot, 10-inch), robust, three-axle, diesel-electric switcher constructed using a single EMD HT-C truck, three D77 traction motors, and half the frame of an EMD SD40-2. Title: BNSF 5759 : Description: Evolution power waiting to exit yard. Unlike this method, tractive effort curves include much more information and so they can publish how well ratios are suited to the engine`s characteristics as well as the fundamental track parameters that driven their choice. 7 MW) C-C diesel-electric locomotive.

The Locomotive GEAC4400CW The GE AC4400CW is a 4,400 horsepower diesel-electric locomotive that was built by GE Transportation Systems between 1993 and 2004. "In order to be classified as an "AH", a locomotive has to have not only an increased (currently to 432,000 pounds) nominal weight, but also (1) steerable trucks, (2) TM3 adhesion control software, (3) software that extends to 36,000 pounds (from 30,000 pounds) the maximum amount of tractive effort that each traction motor is permitted to. Its continuous tractive effort rating was 20% higher (e. The GE U17C diesel-electric locomotive was introduced by GE Transportation as an export model roadswitcher in 1973. These are some of the images that we found within the public domain for your "Ge Es44ac Drawings. The items analyzed are: starting tractive effort, adherent weight, adhesion, power required and power supply, coupling, multiple traction, brake system, interoperability, comfort and safety of the driver, signalling, noise, emissions and energy efficiency among others. That is for a single locomotive. C 45 ACCTE FROM UNION PACIFIC. The Evolution Series, mainly the ES44DC, ES44AC, and ET44AC, are some of the best-selling and most successful freight locomotives in United States history, far surpassing EMD's output.
