The Brookville BL36PH is a four-axle diesel-electric locomotive for commuter trains, produced by Brookville Equipment Corporation.[2] It is built with an MTU 20V4000 V20 engine rated at 3,619 horsepower (2,699 kW) to meet EPA Tier 3 emissions standards.[2] It was the first North American passenger locomotive designed with a 20-cylinder engine since the EMD SDP45 and EMD FP45, originally built in the 1960s.[3] Head end power is generated by a separate, smaller diesel (Caterpillar C-18) generator rated at 670 horsepower (500 kW). The outer shell of the locomotive was designed by Cesar Vergara,[2] who has also designed several other North American passenger locomotives, including the MPI MPXpress, the GE Genesis, the MPI HSP46 and the EMD F59PHI.[4]

Tri-Rail, a Florida commuter rail service operated by the South Florida Regional Transportation Authority, is so far the only customer, with an initial order for 10 locomotives, later expanded to 12.[2][5]

As of February 2022^[update], the locomotive is still listed as an available product on Brookville’s website, although no contracts have been awarded since 2011, and the current Tier 3 design is no longer legal for sale in the United States.
