Columbus, Ind. (October 29, 2004) -

Cummins Inc. (NYSE:CUM) announced the first installation of the Cummins ISB engine in the Thomas Built Saf-T-Liner EF chassis during a school corporation ribbon-cutting ceremony held in Columbus, Ind.

Officials from Cummins, Thomas Built Bus and the Bartholomew Consolidated School Corporation (BCSC) attended the ceremony to celebrate delivery of the new Thomas Built buses, with Cummins ISB engines, which bring cleaner, quieter and safer operations to school buses.

"We are pleased to further extend our relationship with Thomas Built Bus by offering our new low-emission ISB engine in the Saf-T-Liner EF chassis," said Ed Pence, Cummins Vice President - Automotive Business. "It's very important for school buses, which transport the future of our nation, to be equipped with the cleanest, most reliable engines on the market today."

The ISB engine is the latest version of the popular Cummins platform designed for performance, reliability, dependability and the cleanest possible operation. The clean-burning ISB engine is fully compliant and certified to the most stringent EPA emissions standards, which are better for the environment and better for the school children.

The ISB features the latest diesel technology including a High-Pressure Common-Rail (HPCR) fuel system with electronically controlled injectors for maximum fuel efficiency. The HPCR fuel system also plays a significant role in dramatically reducing the level of engine noise. As a result, the Cummins ISB operates with 50 percent less noise at idle and up to 80 percent less noise on the road than its predecessor.

The Thomas Built Saf-T-Liner EF is a transit-style model bus perfect for denser routes that require more seating capacity. The new chassis is recognized for its excellent visibility and maneuverability.

Initial feedback from BCSC bus drivers has been very positive. One driver commented, "The new buses are noticeably quieter and have more pickup." Another driver stated, "I like the way my new bus handles. It has more power and a better turning radius."
