GE Dash 8-40B - Standard DC -- Providence & Worcester #3901 (B39-8; brown, orange)

Built in the late 1980's by GE, the DASH 8-40B diesel locomotives were identified by their dynamic brake gear located along the roof line between the cab and engine compartment, with ventilation provided by large roof-top grilles. These four-axle, high horsepower engines are still in service today in North America. The Atlas N Scale model features directional lighting, painted safety rails, blackened metal wheels, AccuMate(R) knuckle couplers, improved slower speed motor for closer to scale speeds, and new white LEDs.
