ECOTRANS Technologies L.L.C., CSX Transportation and GE Transportation Systems (GETS) Sept. 20 announced plans to jointly develop and deploy ECOTRANS' auxiliary power units (APU) on GETS-manufactured locomotives.


The APU system, an Environmental Protection Agency-certified emission-reducing kit, is designed to keep oil and water warm while the main engine is shut down, and provide auxiliary power for conventional 120/240V AC applications.


The system also can help reduce locomotive engine idling time, which would lower idling fuel consumption about 80 percent and idle emissions about 98 percent, according to a prepared statement.


The companies plan in the near future to market the APUs for locomotive retrofit packages as well as new-unit installations.
