В двух словах - сейчас EMD работает над доводкой нового движка 1010J, так как 710-й не отвечает новым экологическим требованиям.
2000-present
EMD SD70M-2
The year 2004 saw CSX Transportation take delivery of the first SD70ACe units, which were advertised by EMD as more reliable, fuel efficient, and easier to maintain than predecessor model SD70MAC. The model meets the EPA Tier 2 emission requirements using the two-stroke 710 diesel engine.
The following year Norfolk Southern became the first carrier to receive the new SD70M-2 - successor to the SD70M. Like its sister roadswitcher, the SD70ACe, the SD70M-2 meets EPA Tier 2 requirements using the same engine. And like the "ACe", the "M-2" is certified to be in conformance with ISO 9001:2000 and ISO 14001:2004.[25]
In June 2004, The Wall Street Journal published an article indicating EMD was being put up for sale. On January 11, 2005, Reuters published a story indicating a sale to "two private U.S. equity groups" was likely to be announced "this week". Confirmation came the following day, with a press release issued by General Motors, stating it had agreed to sell EMD to a partnership led by Greenbriar Equity Group LLC and Berkshire Partners LLC. The newly spun-off company was called Electro-Motive Diesel, Inc., thus retaining the famous "EMD" initials. The sale closed on April 4, 2005.[26]
On June 1, 2010, Caterpillar Inc. announced it had agreed to buy Electro-Motive Diesel, Inc. from Greenbriar, Berkshire et al. for $820 million. Caterpillar's wholly owned subsidiary, Progress Rail Services Corporation, completed the transaction on August 2, 2010, making Electro-Motive Diesel, Inc. a wholly owned subsidiary of Progress Rail Services Corporation.[3] Although Caterpillar announced that John S. Hamilton would continue in his roles of president and CEO of EMD after the close of the transaction, Mr. Hamilton left EMD for unspecified reasons in late August 2010.[27]
The U.S. Environmental Protection Agency's Tier-4 locomotive emissions regulations on new locomotives went into effect on January 1, 2015. As of that date EMD's 710-engined locomotives (e.g. SD70ACe's) could be built only for use outside the contiguous United States (i.e. Canada, Alaska, Mexico, and overseas). EMD had originally thought the 710 engine could be modified or "tuned-up" to meet Tier-4 standards, but it was not able to meet those requirements while maintaining optimum performance and reliability during rigorous "real world conditions" tests. Development of a Tier-4 compliant locomotive shifted from its original focus on the two-stroke 710 to the four-stroke 1010J engine, derived from the 265H engine.
The first (pre-production) locomotive using the 1010J engine, the SD70ACe-T4, using a 4,600 horsepower (3,400 kW) (4,400 traction hp) 12 cylinder engine was unveiled in late 2015.[28][29] Testing of the new locomotives began in the Spring of 2016.[30] The first two units of a 65 unit order for the new locomotive were delivered to Union Pacific in December 2016.[31]
EMD continues to offer 710-powered locomotives for export as well as "ECO" upgrade packages for modernizing of older locomotives, which sustained their business during the hiatus of locomotive production for the domestic market.
