To the best of my knowledge, Bill's coach (#653) is the first Newell built with the C-12. #714, a 2004 also had the 505 HP C-12 engine in it. By 2005, coach 723 had a 525 HP C-13 and #728 was built with the 550 HP C-15. From the late model 2005's through early 2011 models, Caterpillar, primarily the C-15, was the predominate engine used by Newell. During the 2006 model year, Caterpillar became the standard engine for Newell. Coach 1401, a 2010 had the Cummins ISX 650 and by coach 1415, Newell was using the Cummins ISX as they ran out of Caterpillar engines.
The diesel engines available for use in over-the-road vehicles underwent significant changes during the 2000's as stricter Federal emission standards became effective for model year 2004 and still stricter standards for model year 2007. In 2008, Caterpillar announced that they were going to withdraw from the over-the-road market partially as a result of the EPA emission requirements scheduled to become effective in 2010 (MarketWatch).
