“It is very fitting that we present this Model 579 equipped with the 250,000th Paccar MX engine to TCW,” said Jason Skoog, Peterbilt general manager and Paccar vice president. “TCW understood the value of the Paccar MX engine early on as part of the customer field trial fleet in 2008 before the engine was released to the market in 2010. TCW also plays a critical logistics role for us by delivering parts to the engine factory just-in-time for engine production.”

Founded in 1948 in Nashville, Tennessee, as a small, family-owned warehousing business, TCW over the last seven decades has become one of the largest intermodal operations in the country with a network of transportation services and operations at 10 inland terminals and two port locations.

“It’s a great honor to receive this very import milestone Paccar MX engine and Peterbilt Model 579,” said Scott George, TCW CEO. “TCW’s long-standing relationship with Peterbilt and spec’ing Paccar powertrains in our equipment is based on the common values both of our companies represent, our desire to go above and beyond for our customers.”
