CSX has invested more than $2.8 billion over the last decade to improve its locomotive fuel efficiency and reduce the corresponding emissions. Calculating Fuel Efficiency The ton
Report the total quarterly volume of fuel purchased and placed into locomotive fuel tanks in California in the quarter. 2. The number of intrastate and interstate locomotives in the prior year. 3. Fuel consumption from monitored intrastate units. Railroads should collect fuel consumption data using a method to quantify fuel consumed within the
Using this hypothetical new set of power settings, to produce an average of 6000 HP, the engineer would spend 60% of his time in 8+6+5 (6250HP) and 40% in 8+5+5 (5840HP), resulting in smoother train handling, and an average fuel consumption of about (.60) (355)+ (.40) (326)=344 gallons per hour.
Considerable decrease in operational. efficiency and respectively shunting diesel locomotives huge fuel consumption occurs at. low air temperature. Danger of water freezing in cooling system and
Additionally, MPI''s MP21B gen-set locomotive utilizes multi-engine strategy to minimize fuel consumption by having more than one engine operating only when more horsepower is required.
The effects on fuel consumption of variations in several parameters including train consist, car weight, gradient, average speed, meet strategy, throttle control, locomotive axle arrangement, and train marshalling are examined. Estimates are made of the value, in terms of fuel cost, of weight reduction of freight cars and of selective train
1. Reduced Fuel Consumption. A significant advantage of implementing AESS solutions is a substantial reduction in fuel consumption. With locomotive engines idling for up to
Before modernization, the locomotives had gross specific fuel consumption ranging from 271.3 g/kWh to 277.6 g/kWh. The net fuel consumption vales ranged from 250.3 g/kWh to 256.4 g/kWh. In relative terms the obtained values indicate, that the locomotives with the 12CzN26/26 engine achieved lower specific fuel consumption on average by 9.3%
Modern locomotives, such as Dash9 and SD70 types, use about 0.210 kilograms of fuel per kilowatt hour. Assuming an SD70 at notch 8 is producing 4000 HP,
Experimental data for this locomotive fuel consumption is available in its catalog. As mentioned in Section 2, the fuel consumption of diesel-electric locomotive is a constant rate in each throttle position. The experimental fuel consumption for the SD/GP40-2 locomotive is shown in Table 3 and can also be found in Krug (2006),
Subscribe to Inside Track. The effort paid off again in 2021, as Union Pacific reduced its overall fuel consumption for the third year in a row and helped its customers eliminate an estimated 22.9 million metric tons of greenhouse gas (GHG) emissions by choosing rail over truck. "Union Pacific is committed to moving the needle steadily each
The LEAF® locomotive is designed to minimize fuel usage, reduce emissions, and exceed the performance of a conventional locomotive. LEAF® locomotives have been in operation since 2008. The LEAF® locomotives reduce fuel consumption 45–72% over a conventional locomotive. For every 50 gallons (189.3 liters) per day of diesel not burned

There are four main train fuel types: Steam. Gas. Diesel. Electric. 1. Steam. The steam engine represents a pivotal chapter in the history of trains. The first successful steam locomotive was built by George Stephenson in 1814, and it marked the beginning of the railway era.
How far does the average diesel locomotive go between refuels, and how many MPG does it get? Are they all in the same range, or does it vary? For example, say
EMD SD45. 1⁄2 inches (20.053 m) on some units starting early 1968. The SD45 is a six-axle diesel-electric locomotive class built by General Motors Electro-Motive Division between 1965 and 1971. It has an EMD 645E3 twenty- cylinder engine generating 3,600 hp (2,680 kW) on the same frame as the SD38, SD39, SD40, and SDP40.
In fact, the second quarter of 2020 was the most fuel-efficient quarter in CN''s history! During April, May and June, the railway used only 0.88 US gallons of locomotive fuel per 1,000 gross ton miles (GTMs), on average. This record-breaking performance resulted in a 2% improvement in fuel efficiency over Q2 2019, avoiding
The presented results of fuel consumption include the values determined on the resistor at set operating points and in real operating conditions. Using the assumptions of the vehicle''s operating time density characteristics, a computational method for assessing the fuel consumption of traction locomotives was developed.
In the paper, the BSFC parameter determined and analyzed and the power/operating speed ranges of the diesel engine 12LDA28, which equip the Diesel-electric locomotive 060 DA, are determined so that it operates with optimal fuel consumption. The analysis uses the experimentally data that is found in the literature [3].
Customer deployments are experiencing up to a 15% reduction in fuel consumption, lower in-train forces and more consistent train operation, Progress Rail officials said. Talos also
Fuel Test Parameters GE Transportation engaged a nationally recognized independent research laboratory to conduct the Tier 2 locomotive fuel consumption testing. The lab conducted the tests in late January and early February 2009. A Class 1 Railroad supplied two GE and two EMD test locomotives of similar age and road use for
Fuel usage is figured by Gallons Per Hour(GPH) at idle and full throttle.I imagine that locomotive fuel capacities today are probably 5,000 gallons.During the 1970''s locomotives such as the SD45,SD40-2,U30C,and U33C were generally 4,000 gallon.A lot depends on the RPM''s of the engine at idle and max.For example,the SD40-2 had an idle
Derived from first principles of power, tractive effort and train resistance, the model assumed a locomotive fuel consumption rate of 20.9 horsepower-hours per gallon Passenger Rail Energy Efficiency Research and Benchmarks 19 to calculate efficiency in terms of seat-miles per gallon. The fuel efficiency calculation can be expressed as: S 8.16
Reduced Fuel Consumption. A significant advantage of implementing AESS solutions is a substantial reduction in fuel consumption. With locomotive engines idling for up to 40% of their operational time, AESS technology can save up to 30% of total fuel usage. This not only leads to cost savings but also reduces the environmental impact of rail
A road locomotive would need 3,300 kilowatts of power – or 10 times what''s available from fuel cells that can fit on a locomotive today, Moslener says. The
Substantial Fuel Savings: The heart of SmartStart''s value proposition lies in its ability to deliver significant fuel savings. By reducing unnecessary idling time, SmartStart minimizes fuel consumption and associated costs. Studies indicate potential savings of 5,000 to 8,000 gallons of fuel per locomotive annually, resulting in
The average fuel consumption of the TEM2 shunting diesel-electric locomotive in 2009, before modernization, was 11.86 l/h. In 2015, the average fuel consumption of the new TEM TMH diesel-electric locomotive was 6.12 l/h, a reduction of 48%. On average, fuel consumption of the modernized 2M62M locomotive (l/h), has
Using this prototype locomotive between two traditionally powered locomotives reduced fuel consumption and greenhouse gas emissions by at least 10%. Battery-electric Locomotive: Railroads, suppliers and academic institutions are testing and running real-world pilots of battery-powered line-haul locomotives that transport freight across the
An outposted helper set would be a good example. Tenders are also used to extend the range of a locomotive consist, such that it can be fueled where the cost of fuel is cheap, and allow it to pass through areas of high cost without fueling. This has been done in the past to avoid states with high fuel taxes.
