Progress Rail announced it has successfully completed initial emissions testing of a new switching locomotive, the EMD24B, and has begun the process of certifying the locomotive for EPA Tier 4 emissions standards.

Rated at 2,000 horsepower, the EMD24B comes equipped with a Caterpillar 3512C HD engine and aftertreatment technologies to lower emissions. The four-axle unit was constructed with a remanufactured underframe and cab from an existing General Motors Electro-Motive Division GP-40 locomotive of pre-1973 vintage.

The design and manufacture of the EMD24B involved various teams within the Albertville, Ala. company, which is a unit of Caterpillar, including Progress Rail’s repower engineering team, employees from the company’s Patterson, Ga. facility, and its Brazilian subsidiary, Zeit, which provided the locomotive’s control system.

The locomotive will be operated by Pacific Harbor Line in the ports of Los Angeles and Long Beach.
