Yes, this loco was built entirely by Brookville at their facility in Brookville, PA. It's the first of 12 such units that they are building for CTDOT. A few vital statistics on the BL20GH:
132 tons. The mechanical power generated by the MTU Detroit Diesel Series 12v4000 diesel engine is transferred to the Kato main traction alternator and its excitation is controlled by the TMV Traction Control System. Propulsion power is directed from the main traction alternator through switch gear located in the main electrical cabinet.
Two Blomburg B-B style trucks are located under each locomotive. These contain two D78 traction motors each of which is directly geared to an axle and pair of driving wheels.
These units are also equipped with Caterpillar C15 head end power units producing 480 volt, 3 phase electrical power for passenger cars, providing lighting and heat, and air conditioning.

Just to explain how much things have changed, the Caterpillar C15 Engine is used in Tractor Trailer trucks, usually rated for around 550 HP (in a truck). Amazing how technology has adapted an engine of that size to be used in a locomotive.

The CAT C15 engine is not the prime mover. its a HEP unit. Head End Power. Its used to generate power for passenger cars for their interior lights, heating, air conditioning and such. Our (New Jersey Transit) F40PH-2CATs have CAT engines in them for HEP. That is a dam big Brookville. Looks a lot like an EMD. How new are these?
