USA: Testing of the solution coupled with two locomotives was conducted at MxV Rail in Pueblo. The US company notes that the tests confirmed reduced fuel consumption under high load and a decrease in greenhouse gas emissions.
The manufacturer has not disclosed the technical specifications of the tender, named Volt. Volt consists of several battery units housed in containers on a specialised platform. The traction batteries can be charged both from stationary charging stations and through regenerative braking. The design allows for their rapid replacement using a forklift.

Volt enables a diesel locomotive to operate in fully battery or hybrid mode, providing a power boost during acceleration, going uphill, or hauling heavy trains. The company claims the solution can reduce fuel consumption by up to 77% and maintenance costs by decreasing wear on a range of components. Dayton-Phoenix indicates it anticipates demand for Volt from mining companies.
Testing of a similar battery tender coupled with a locomotive is expected to begin this year in Australia. The project is being implemented by freight operator Aurizon for the US aluminium company Alcoa.
