The Single-Engine Advantage
Unlike Genset locomotives that use multiple diesel engines, KLW locomotives use just one diesel engine to generate tractive power. Because Genset locomotives have two or three engines, they are naturally more complex than a single-engine locomotive. Gensets have 2-3 engines worth of filters, parts, and other related components and they also require complex electronics in order for the 2 or 3 engines to work properly together. In comparison, KLW's single-engine locomotives are less complex, more reliable, and perform better than multi-engine locomotives. Additionally, KLW units use the common AR10 traction alternator to generate electricity whereas gensets are forced to use expensive high-speed alternators that many railroads are not familiar with. As a result, KLW locomotives offer clear performance and reliability advantages over Genset locomotives while providing a familiar feeling to operator's that are used to traditional EMD and/or GE equipment.
Emit Less - Reduce Emissions up to 85%
By utilizing MTU engines, KLW offers some of the cleanest single-engine locomotives ever created. When compared to the locomotives they typically replace, KLW units can reduce combined NOx, PM, CO, and HC emissions by up to 85%. Even more surprising, the KLW product line is up to 50% cleaner than some of our closest green competitors.
KLW locomotives also reduce fuel consumption by up to 60% which has some added environmental benefits. According to the US Energy Information Administration, 22.38 lb of CO2 are produced from burning just one gallon of diesel fuel. This means a single KLW locomotive is likely to save hundreds if not thousands of tons of CO2 from being emitted during its lifetime.
Lastly, with the tractive effort increases our locomotives provide, more work can be accomplished. For some operations this results in locomotives running less overall, or for larger trains, it could mean fewer locomotives are needed to do the same amount of work, resulting in additional emissions and fuel savings.
Consume Less - Up to 60% in Fuel Savings
In addition to low emissions, KLW units offer low fuel and oil consumption. KLW has found that our locomotives offer up to 60% in fuel savings for our low horsepower SE10B and up to 20% in savings for our other models. Depending on the duty cycle and locomotive being replaced, KLW units can save thousands to tens of thousands of dollars in fuel consumption every single year. Our units are also equipped with Automatic Engine Start Stop (AESS) which helps reduce fuel consumption by shutting down the engine when idling for long periods of time.
With improvements in tractive effort, our units may also spend less time operating and/or be able to replace higher-horsepower locomotives. Although this varies from operation to operation, in some cases fewer KLW units can do the same amount of work as traditional units, resulting in additional fuel savings that are hard to quantify.
Do More - Increase Starting Tractive Effort up to 40%
Since its completion, the KLW 2250 has demonstrated that it is able to move freight better than many of the locomotives in use today. The benefits to increased tractive effort can vary depending on the duty cycle of the locomotive. In yard switching applications, KLW locomotives are able to accelerate quicker than many other locomotives, which makes kicking cars or moving large consists much easier. For road-switching or line-haul applications, the increase in tractive effort means more cars can be hauled with fewer locomotives. A good example is a railroad located in South Carolina that was able to go from needing five locomotives for their large grain trains down to just three. This reduction in needed power has allowed this railroad to save a lot of money on fuel, oil, and maintenance costs and there are added environmental benefits that are achieved with the use of fewer locomotives.
Retaining Time Proven Components
At KLW, we understand that railroads really like what they know works, which is why our repower package incorporates as many industry-standard components as possible. KLW locomotive use rebuilt trucks, a AAR control stand, the AR10 alternator, common air brake components, and more items that most operations are already familiar with. By utilizing these common components, operations and maintenance crews will only need minimal training and finding parts is also a much easier task compared to some of our competition.
