Brookville built a single demonstrator for the Connecticut Department of Transportation (CDOT); CDOT and the Metro-North combined to order eleven more in 2008, for a total of twelve locomotives. CDOT owns six of the locomotives, which it painted in its "McGinnis" paint scheme, named after former New York, New Haven and Hartford Railroad president Patrick B. McGinnis. This scheme consists of a black nose, with a white stripe and an orange rear, with white New-Haven lettering overlapping the orange rear. The first public run occurred on June 9, 2008.
A nearly identical locomotive, known as the BL20G, operates on the Staten Island Railway. Four were built by Brookville Corporation in December 2008. These locomotives lack the head-end power generator and the associated ventilation grates of the BL20GH. They are used in work train service only.
