Brookville BL36PH

The Brookville BL36PH is a four-axle diesel-electric locomotive built by Brookville Equipment for commuter rail service. It has an MTU 20V4000 V20 engine rated at 3,619 hp and meets EPA Tier 3 emissions standards. It was the first North American passenger locomotive to feature a 20-cylinder engine since EMD's SDP45 and FP45 models from the 1960s. Head end power is generated by a separate, smaller Caterpillar C-18 diesel generator rated at 500 kW. The BL36PH's shell was designed by noted North American passenger locomotive designer Cesar Vergara.

South Florida's Tri-Rail is the BL36PH's only customer, placing an initial order for 10 in 2011 and adding two more later for a total of 12.

, the BL36PH is still advertised on Brookville's website where it has been rebranded as the "Eagle", even though no orders have been placed for it since Tri-Rail's in 2011, and its Tier 3 design is no longer legal for sale in the United States.
