Created specifically for port, mining, industrial in-plant, and commercial yard switching (shunting) applications, the LEAF locomotive maximizes tractive effort while minimizing fuel costs and emissions.
LEAF® locomotives reduce NOx emissions and particulate matter by 84% and meet EPA emissions standards for Tier 3 or Tier 4 diesel engines. For every 50 gallons (189.3 liters) per day of diesel not burned, the LEAF reduces GHG by 400,000 lbs. (181,437 kg) per year.
Lower Fuel Usage
The LEAF® locomotives reduce fuel consumption 45–72% over a conventional locomotive.
Easy to Maintain
LEAF® locomotives are built with readily available parts, making future maintenance easy and cost effective.
The LEAF is powered by a single or double Cummins QSX15-L3 600 hp genset. Meets EPA emission standards for Tier 3 and Tier 4 engines. Tier 2 emissions packages are also available.
The proven track record of the LEAF in numerous switching operations makes this competitively-priced locomotive an exceptional value for any rail yard. Learn more about how the LEAF can increase efficiencies and reduce costs in your operation. Find a dealer.

Efficient and Clean Performance
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 at Railserve sites since 2008.
Fuel consumption in comparable operating circumstances results in a 72.5% savings in fuel costs.
*Each switching operation will have unique locomotive operating demands.

What is a Genset locomotive?
The term genset, aka generator set, refers to the type of engines used to provide power to the wheels of the locomotive. Where a conventional locomotive would use one large (typically 1,500 hp to 3,000+ hp) diesel electric engine, the genset uses one to three smaller, modern, ultra-low emissions, diesel electric engines to provide the power. A computer controls this set of smaller engines for maximum efficiency — starting and stopping each engine as needed for the power required.
More efficient by design
Genset locomotives are also equipped with advanced control logic that increases tractive effort by about 15% tightly controlling the wheel RPM and ground speed. The improvement in tractive effort further reduces the need for additional horsepower. The long-term fuel savings from a genset, when compared to a conventional locomotive, can be quite remarkable. Most genset locomotives are programmed to shutdown after the locomotive has not moved for five minutes, thus greatly reducing idle time. Start times for the genset are also much shorter than a conventional locomotive. A genset can be re-started at the push of a button, while the conventional locomotive engine has a lengthy 30 minute startup process.
The engines used in modern gensets emit 80+% less NOx from the fuel that is burned. Further, because they are more fuel efficient, they reduce the CO2 emissions dramatically. Each gallon of diesel that is burned yields 22.4 lbs of CO2. Thus, if a genset locomotive replaces a conventional diesel locomotive, the 50% fuel savings will often generate over 250,000 lbs less CO2. The lower fuel consumption of a genset greatly reduces the NOx emissions and will usually meet EPA Tier 3 emission standards for diesel powered locomotives. This is why genset locomotives are considered “green and clean.”
Gensets vary in cost, but some models are known to be comparable in price to an older, 30 to 40-year-old locomotive. Gensets however, meet more stringent EPA standards and have more readily available parts than older locomotives. All this combined with the fuel savings make genset locomotives a great choice for most yard switching applications and certain short line or line haul operations.
