CSX Transportation relies heavily on John Deere diesel engines to power its fleet of railway maintenance equipment. Since 2008, CSX has been standardizing its equipment with John Deere engines, which now drive 95% of its maintenance machines. The company chooses John Deere due to their compact size, wide range of horsepower options, interchangeable parts, and reliability in harsh conditions. Standardizing with John Deere has improved maintenance and reduced costs for CSX Transportation.
