Brookville Equipment Co. of Brookville, PA has perhaps the most ambitious view of the multi-engine concept, taking it a few steps further. Their CoGeneration line of road switchers is being designed not only to run with multiple engines, but to have the option of electric or battery power built in as well. The CoGen line also features regenerative braking that generates power for the systems while braking at speeds down to 0.6 mph.

The prototype unit in the CoGen line was built using Maine Central 259, an EMD GP38. The unit features three Cummins QSK-19 engines for power. Those engines are rated at 700 hp each, giving the unit an agregate horsepower rating of 2,100. Brookville literature mentions the use of all-new construction frames, but the first one is definitely a recycled unit.

Visually, this unit is quite a bit different from any other genset offerings, in that it has a more conventional height long hood, larger radiator fans, and the stock-looking EMD cab and nose.

By combining the standard configuration with particulate exhaust filters, the Brookville says its CoGen unit can reduce hydrocarbon emissions by up to 97%, NOx emissions by 65%, CO emissions by 75%, and particuate emissions by 93%.

No model designations have been anounced by Brookville as of March 2008 for the three engien unit, but a twin-engine unit for Metro-North has been designated a BL14CG, lending credence to the idea that the three-engine unit will be a BL21CG.

Also, in 2008, Brookville built a pair of twin enigne CoGen units for Metro North as part of an 18-unit order that has included a number of single engine locomotives. These are the first twin engine units offered by Brookville.

Twin engine unit being built for MTA in New York. The unit has two Cummins QSK-19 engines, 1,400 total horsepower. Built on a new frame, but it rides on Flexicoil switcher trucks ala some of CN's GP7's.
