Union Pacific (UP) has unveiled a new experimental freight locomotive, the UP 9900, at its Roseville Yard in California as part of a $20m investment to meet the US Environmental Protection Agency (EPA) Tier 4 locomotive standard.

The UP 9900 will test the emissions-reductions abilities of three types of technologies, including exhaust gas recirculation (EGR), diesel oxidation catalysts (DOC) and diesel particulate filters (DPF).

The locomotive, which is one of a series of 25 trains to be tested at two Union Pacific rail yards, will be used for operations in northern California on the 200 miles of track surrounding its base in Roseville.

Testing of the locomotive is part of the company’s strategy to design, build and test technologies that will help reduce emissions.

The tests are scheduled to continue until the end of 2014, with various emission-reducing technologies.

The company partnered with Electro-Motive Diesel (EMD) to develop the locomotives and improve the fuel-efficiency of its locomotive fleet, as well as reduce the standard freight locomotive engine size in UP 9900 to create the space needed to install EGR, DOC and DPF.

Union Pacific engineers have reduced engine size of the long haul locomotive, which will create space needed to install technologies in its body.

The locomotive is expected to achieve a 45% reduction in the oxides of nitrogen emissions compared to the Tier 2 standard and an 85% reduction in particulate matter emissions.

Over the next year and a half, the company and the California Air Resources Board will analyse the UP 9900s emissions-reductions capability.
