DOT FRA - Aftermarket Technologies for Improving Locomotives - MRAS

The Federal Railroad Administration (FRA), a division of the Department of Transportation (DOT), is seeking to conduct research aimed at improving the efficiency and performance of older locomotive engines. This initiative is particularly focused on supporting shortline and regional railroads, which often operate with limited financial resources and rely on aging locomotive fleets. The FRA's goal is to explore cost-effective aftermarket technologies, such as fuel additives and engine kits, that can enhance locomotive efficiency without necessitating the purchase of new equipment.

To address these challenges, the FRA has outlined a comprehensive research project that will investigate various aftermarket technologies used by smaller railroads in the United States. The selected contractor will be responsible for identifying these technologies, conducting tests both in laboratory settings and on a government-furnished research locomotive, and analyzing data to assess their effectiveness. The project aims to determine how these technologies can optimize combustion processes and reduce energy losses in older locomotives.

The scope of work includes several key tasks: identifying suitable aftermarket technologies for testing, procuring these technologies through established supply chains, developing detailed test plans that adhere to industry standards, conducting minimally invasive field tests on an operational locomotive provided by the FRA, and collaborating with industry partners like the American Shortline & Regional Railroad Association (ASLRRA). This collaborative approach ensures that the research is grounded in practical applications relevant to current railroad operations.

This 18-month project represents an important effort by the FRA to support smaller railroads by providing them with viable options for modernizing their fleets without incurring prohibitive costs. By leveraging existing aftermarket solutions, this research has the potential to deliver significant improvements in fuel efficiency and performance for legacy locomotives across shortline networks nationwide.
