The Railserve LEAF Gen-Set Locomotive with Single Cummins genset
The Railserve LEAF Gen-Set Locomotive

Original Railserve LEAF

Created specifically for port, mining, industrial in-plant, and commercial yard switching (shunting) applications, the Railserve LEAF Gen-Set locomotive maximizes tractive effort while minimizing fuel costs and emissions.

Lower Emissions

Railserve LEAF® locomotives reduce NOx emissions and particulate matter by 92 and 99% repectively and meet EPA emissions standards for Tier 4 and Tier 3 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 Railserve LEAF® locomotives reduce fuel consumption 45–72% over a conventional locomotive.

Easy to Maintain and Operate

Railserve LEAF® locomotives are built with readily available parts, making future maintenance easy and cost effective. Plus, operation of the LEAF is nearly indistinguishable for crews accustomed to widely used SW or GP-type locomotives.


The original Railserve LEAF is powered by a single Cummins QSX15-L3 600 hp genset. Meets EPA emission standards for Tier 3 diesel engines. Tier 2 and Tier 4 emissions packages are also available.

Exceptional Value

The proven track record of the Railserve LEAF in numerous switching operations makes this competitively-priced locomotive an exceptional value for any rail yard. Learn more about how the Railserve LEAF can increase efficiencies and reduce costs in your operation. Please contact Railserve today.

Real World Example

Fuel & Emissions

Railserve tracks fuel consumption of its genset and conventional locomotives.

Efficient and Clean Performance

The Railserve LEAF® locomotive is designed to minimize fuel usage, reduce emissions, and exceed the performance of a conventional locomotive. Railserve 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.
