This computer program produces a family of monthly reports giving mileage and distribution of time (service status) by locomotive model. Input consists of mileage and time data for each unit in locomotive service. This is obtained from the car movement history file. Locomotive model and model group is obtained from the diesel records master. Output consists of four reports. These are: 1. Report by model group and within model group by model giving number of units in service, average miles per month, average miles hour, distribution of hours in percent in the following caregories, freight, passenger, switching, in-tow, in-shop, and idle. The report also shows the effective utilization for each model which is defined as the ratio of the average speed to the rated speed times percent hours in service. 2. A listing by unit of low-utilization units showing the bottom five percent of each model and giving the same information as in report 1. 3. A listing by unit for high-utilization units. 4.
