DWS-120

The DWS-120 utilizes 120VAC power from an external source to power a 35kw (120,000 BTU/hr) heater and water pump. The system circulates engine coolant through the locomotive in order to keep key systems warm.

DWS-APU

The DWS-APU features a 9.5 HP diesel engine to provide 72VDC to power a 35kw (120,000 BTU/hr) heater, water pump, oil pump (if equiped), and also charges the locomotive's batteries. The system circulates coolant through the locomotive in order to keep key systems warm. If equiped with the oil pump option, oil may be circulated through the engine to keep it warm.

Cost of diesel fuel per gallon for the locomotive.

This is the average fuel usage of the locomotive while idling in gallons per hour.

This is the number of hours the locomotive would spend idling per week with no idle reduction system.

This is the number of weeks per year where it is expected the locomotive will be required to idle in order to maintain water temperature and prevent freezing.

The locomotive type determines which set of EPA data to use when calculating emissions.
