BHP Billiton Places Additional Order
for Electro-Motive SD70ACe Locomotives High Traction Locomotives
for Iron Ore Mining Operations in Australia

LaGrange, Illinois - Electro-Motive Diesel, Inc. announced today that BHP Billiton Iron Ore Pty. Ltd. (BHPBIO) will take delivery in early 2007 of ten SD70ACe locomotives for use in mining operations in northwest Australia. This follows on the heels of a recent order for 14 locomotives of the same type.

Electro-Motive's SD70ACe model, which meets the strict U.S. EPA (Environmental Protection Agency) emissions standards, has been developed for the North American freight locomotive market as well as other heavy haul railways around the world. This model uses the highly reliable 710 Series diesel engine and is rated at 4,300 traction horsepower. The SD70ACe employs an AC (Alternating Current) traction system to develop high wheel-rail traction for heavy haul service. For this order, EMD is designing an isolated cab to improve operator comfort, demonstrating an emphasis on continuous product improvement for its customers.

According to Frank Ward, Regional Vice President of International Sales for Electro-Motive, "We are delighted that BHPBIO has expressed further confidence in EMD by placing an additional order for EMD products. BHPBIO has chosen the energy-efficient, low-emissions SD70ACe locomotive for its operations. It means a great deal to EMD to enjoy the trust of this key customer."

The locomotives will be built by Electro-Motive in London, Ontario, Canada. EDI Rail, a division of Downer EDI Limited, sold the locomotives and will commission and support them in service. EDI Rail represents Electro-Motive in Australia and also manufactures and maintains locomotives with Electro-Motive technology.
