Transport Diesel Service Inc. was established in late 1982. It opened in an existing building just west of today's Logan location and had only two very small service bays. It quickly became apparent this building could not accommodate the rapid growth they were experiencing. In 1985, a new facility was constructed with eight service bays. As the business continued to grow, four more new bays were added in 1992. The company then expanded to the Tremonton area in 2001, with a new facility having 11 service bays. Once again more space was needed, and in 2004 an additional 6 bays were added. What started out as a small business with only 4 employees has now grown to over 55 employees. The two shops currently employ 37 mechanics and 18 office/parts personnel.
