In light snow and sub-freezing conditions a ground person updates the crew of Charger 4628 as it sits in the Denver Union Station while passengers load. These Chargers are impressive, with a slightly higher horsepower than the P42DC Genesis (4,400 hp vs 4,250 hp), slightly higher road speed (125 mph vs 110 mph) and incredibly brighter headlights thanks to LED's. You certainly know that a Charger is coming vs another engine type.
