ATSF 98 is a 1967 General Motors Electro-Motive Division FP45 diesel locomotive once owned by the Atchison, Topeka and Santa Fe Railway and is today on permanent, operational display at the Orange Empire Railway Museum in Perris, California USA.

With its , 20-cylinder prime mover and six traction motors, the FP45 was intended for fast passenger service and is geared to run in excess of . ATSF 98 is especially notable as being the last passenger locomotive ever purchased by the railroad and was used on Santa Fe's finest passenger trains, including the Super Chief between Chicago and Los Angeles. Relegated to fast freight service in 1971 when passenger rail operations were transferred to Amtrak, the FP45 was donated in operating condition less its air conditioner by the Burlington Northern Santa Fe in 1997.

The locomotive's sheer size in comparison to the museum's relatively small, low-speed main line limits its use to occasional demonstration service and special excursions. It is maintained in service-ready condition and is sometimes used on off-property work trains.
