[8] Although mechanically similar to earlier SD70 units, the SD70ACe rides on a new underframe and uses mostly new sheet metal above the frame. GE Transportation has invested $600M in the Evolution Series since its introduction in 2005 and is the first supplier of Tier 4 locomotives for Class 1 railroads. Later Tier 3 models are rated at 4,500 horsepower (3,400 kW). CSX has some 200 units on or coming onto its roster, while Iowa Interstate ordered 14 units. That is for a single locomotive. Wheels: 41 in. 'The ES44C4 was designed to be comparable with the ES44DC in terms of tractive effort, but be cheaper to maintain, more comparable to the ES44AC. Power is the force needed to run a train at a certain speed. Re: What is the point of the GE ES44C4? by TrainWatcher » Sun Aug 12, 2012 3:59 am To be honest, the original A1A design really makes sense and with the newer technologies that are coming within railroad technology, you can take an old stand-by design and really add to it to make it more cost effective on a newer six axle truck design. Tractive effort is indeed the forte' of the diesel electric. " One of the first tasks of the members was to submit ideas technologies and/or vehicles about which information would be gathered.

At the present time, mainline American railroads generally maintain dual fleets of locomotives. 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. These are some of the images that we found within the public domain for your "Ge Es44ac Drawings. CSX ES44AC #977 with the CSX designation of "AH" due to: 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 produce, and (4) GE's Rail Cleaner, which directs high-pressure air onto the rails in. The railroad operates approximately 21,000 route miles (34,000 km) of track. CSX began receiving an order of 200 ES44ACs (referred to by CSX as the ES44AH) in December 2007. Actually an ES44AC 'H' loco could produce more tractive effort - the software limit per axle is 155 kN - but it's deliberately restricted overall to keep the in-train forces sensible. NORFOLK SOUTHERN/PENNSYLVANIA RAILROAD Broadway Limited is excited to release its most modern diesel locomotive ever -- The GE ES44AC. From 2005 to 2015, the ES44AC became GE’s standard North American locomotive and a compelling platform for others worldwide. CSX has some 200 units on or coming onto its roster, while Iowa Interstate ordered 14 units. A leaf numbered 76a appears between leaves 76 and 77, a leaf numbered 78a between 78 and 79, and a leaf numbered 103a between 103 and 104. The EMD SD70 is a series of diesel-electric locomotives produced by Electro-Motive Diesel in response to the GE Dash 9-44CW. GER/LNER/BR Class N7 0-6-2T. Since we have a formula for calculating train weight based on horsepower, we can sort of calculate the rolling resistance for a boxcar given that a ES44AC generates 4000 horsepower and can move approximately 25 100 ton freight cars: as given here, a ES44AC has 183,000 pounds of starting tractive effort (starting from rest, so considering static. John, CSX's heavy GE ES44AC locomotives, which CSX calls ES44AH, are rated at 200k lbs of Tractive Effort, that converts to 890 kN. transition is the term applied to the change of the traction motor electrical connections, so that desired tractive effort can be obtained within the voltage and current limits of the main generator. EMD’s 16-710-G3C-T2 prime mover, rated at 4,300 horsepower (3,200 kW). this means that as a traction motor rotates it builds up a counter voltage which acts in. That sounds like a lot, but that's not even as much as the weight of a loaded coal car. Beginning in 2012, newly built SD70ACe’s were EPA Tier 3 compliant. Originally Posted by OGR Webmaster: Originally Posted by Schumann: According to Steamlocomotivedot. I can say that AC units do have a better job then DC units. These include versions with direct current traction motors (ES44DC), a "heavy version" designed for higher low-speed tractive effort (ES44AH), and a version with two traction motors per truck instead of three (ES44C4). Tractive Effort. View and Download Lionel LEGACY SD-70ACe owner's manual online. Figure 15: The same kind of frame with a pocket milled in the fuel tank to take a LokSound Micro V4 (or Select Micro), with channels through the back of the fuel tank, across the bottom of the frame and up the sides to get the wires to the lighting PCB to hook the decoder up. CSX has some 200 units on or coming onto its roster, while Iowa Interstate ordered 14 units. Models Currently, six different Evolution Series models have been produced for the North American market. ES44AC ballasted to 420,000+ lbs for added tractive effort, custom-built for CSX Transportation. net - Rolling Stock - GE ES44AC, ES44DC and ES44C4 The Evolution Series from General Electric Transportation is a product of 60 years of serious product development.

Sometime between 2012 and 2013, BNSF experimented with LNG (liquified natural gas) for testing and evaluation purposes as an alternative to diesel fuel (similar to the BN's light natural gas tests from the 1990s). [1] The first demonstration unit was released in August 2011 from NRE's Mount Vernon shops in Southern Illinois. , and the radius of the wheel (1/2 the diameter). 2900, 3765 and 3766 by their calculation were the most power Northerns Built. Actually an ES44AC 'H' loco could produce more tractive effort - the software limit per axle is 155 kN - but it's deliberately restricted overall to keep the in-train forces sensible. Broadway Limited is excited to release its most modern diesel locomotive ever -- The GE ES44AC. I honestly think that the P42 units are beyond the point being able to undergo a conversion. The idea is that the unit with 4 AC traction motors will be able to produce a similar amount of tractive effort as a normal DC traction ES44DC with 6 traction motors. Built from 2004 to 2014 in the United States, the SD70ACe was originally designed to comply with EPA Tier 2 locomotive emissions regulations. The EMD SD70 is a series of diesel-electric locomotives produced by Electro-Motive Diesel in response to the GE Dash 9-44CW. There are GP40-2 and SD40-2. Tractive effort: 59,700 lbs.

In order to be classified as an "AH" by CSX, a locomotive has to have not only an increased. [15] 3 ES44AC units were delivered in 2015, numbered 514-516. far too many to list here. The BNSF ES44C4's are 4400HP motors are only rated at 105,000lb effort. This software package is now standard on their ES44ACs as well. 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. Not many of the Alco HH series have been preserved. I caught this photo in Gold Run, of a GE C44ACCTE -- UP's description of an AC-driven General Electric unit with 4,400 hp, possessing CTE or Controlled Tractive Effort. Freight Diesel‐Electric Locomotives Paralleling the comments above on locomotive weights and STE in Table III‐2, Table III‐3 compares a 4‐ axle EMD GP38‐2 to a 6‐axle NRE 3GS21C. The Tractive Effort estimation formula, which I found in a paper from Virginia Tech University. The list is updated monthly, removing the current months releases from the list, and adding new iems that we are taking advance reservations for. The ES44AC (Evolution Series, 4400 HP, AC traction) replaces the former AC4400CW model in GE's range. RE: Better tractive effort? Most RRs have a computer limitation on the AC44 and ES44AC to limit starting tractive effort to 180,000 pounds (some may be lower). They are rated at 157,000 lbf (700 kN) continuous tractive effort (191,000 lbf (850 kN) starting). [16] 3 ES44AC units were delivered in 2015, numbered 514-516.
