<br />OPERA nONS AND MAINTENANCE <br /> <br />. <br /> <br />This section presents the preliminary annual operating and maintenance (O&M) cost <br />estimates for the Northstar Commuter Rail System and the associated Feeder Bus <br />System. Overall, the Northstar commuter rail system annual O&M cost estimate in 1999 <br />dollars is $9,527,000 and the Northstar feeder bus system annual O&M cost estimate in <br />1999 dollars is $576,000. The total annual O&M cost estimate in 1999 dollars is <br />$10,103,000. <br /> <br />Commuter Rail Operations and Maintenance <br /> <br />The Commuter Rail O&M cost estimates are determined from input statistics consisting <br />of physical attributes and annual operating characteristics, which in turn, are defined by <br />the commuter rail system's operating plan. Key assumptions reflected in the Northstar <br />Commuter Rail system input statistics are as follows. <br /> <br />· Operating Schedule - this schedule is based on the Concept B Commuter Rail System <br />plan as written in the commuter rail system section of this summary. <br /> <br />. <br /> <br />· Train-Hours - the revenue train hours are calculated from the commuter rail timetable <br />provide in the service plan and are based on Burlington Northern Santa Fe's (BNSF) <br />operational simulations. For the Concept B system plan, there are 21.8 revenue train- <br />hours of service each weekday and 11.6 revenue train-hours of service each weekend <br />or holiday. <br /> <br />· Train Length - the ridership forecasts are used to determine the train lengths for each <br />of the peak trains. The Concept B system plan requires four "in-service" trainsets <br />during the peak weekday operations (4 locomotives and 12 passenger cars). <br /> <br />· Train-Miles and Car-Miles - the train-miles are calculated from the Concept B <br />system plan according to the track mileage between each train trip's origin- <br />destination city pair. For Concept B, there are 858.8 train-miles of service each <br />weekday and 390 train-miles of service each weekend day or holiday. The car-miles <br />are calculated assuming the preliminary train consist of three passenger cars for each <br />train. <br /> <br />· Railroad Route-Miles - in Concept B, it is assumed that the system plan will require <br />maintenance and use of the double tracks between Minneapolis and Elk River due to <br />the additional trainsets running between these stations. Therefore, the Concept B <br />railroad route-miles are 95.1 miles. <br /> <br />· Annualizing Factors - train trips, revenue train-hours, train-miles, and car-miles are <br />annualized using factors of 250 weekdays per year and 115 weekend days and <br />holidays per year. <br /> <br />. <br /> <br />Draft Commuter Rail Technical Feasibility Study <br />December 1998 <br /> <br />6-1 <br />Operations and Maintenance <br />
