1. Commuter Rail Vehicle Technology September 2006

2. Commuter Rail Vehicle Technologies for FasTracks Diesel & Dual Mode Locomotive Hauled Coaches (LHC) Electric Multiple Units (EMU) Diesel Multiple Units (DMU)

3. Detailed Cost Information for Input into the Corridor EISs Original FasTracks Plan assumed LHC technology in budget Current analysis compared EMU and DMU commuter rail vehicle technologies to the Original FasTracks Plan: Capital costs (including vehicles) updated to $2006 Operating and maintenance costs updated to $2006

4. Options Analyzed: Each corridor as stand alone Two and three corridors sharing same vehicle technology Base diesel price: $2.75/gallon Additional analyses of $2.50 and $3.50/gallon Base Electric price: $0.085/kilowatt hour Additional analysis of $0.10/kilowatt hour Base annual inflation rate: 3% Additional analysis of 0% inflation Three Corridor Analysis: East, Northwest and North Metro

5. 30 Year Capital & O&M Costs* for EMU and DMU Compared to LHC (Original FasTracks Plan) (Inflated Dollars) Comparison of Capital and O&M Costs Assumptions* Diesel: $2.75/gallon Electricity: $0.085/kWh Inflation: 3%/year Each corridor analyzed independently (no savings for same technology in multiple corridors) EMUDMU East Corridor- $ 215.29 M- $142.74 M North Metro- $37.89 M- $84.16 M Northwest Rail+ $10.3 M- $15.2 M

6. East Corridor

7. Results of Analysis: East Corridor EMUs are more cost-effective: EMU: - $215.29M, DMU: - $142.74M Travel time savings allow lower operating costs as fewer EMU trainsets required EMU saves an average of $2.22M/year in O&M costs over DMU Civil cost savings realized as EMUs can negotiate steeper grades Higher cost to electrify corridor is offset by reduced civil and operating costs FTA Cost-effectiveness index (CEI) met – eligible for federal funding

8. Next Steps East Corridor: Evaluation of options to develop Preferred Alternative for alignment, stations and technology will include: Commuter rail vehicle technology cost analysis Environmental factors, including community impacts Mobility benefits, including travel time and ridership FTA cost-effectiveness criteria Committee, stakeholder and public meetings will be held September through early November

9. Northwest Rail

10. Results of Analysis: Northwest Rail Corridor DMUs are more cost-effective: EMU: + $10.3M, DMU: - $15.2M Shorter train lengths than East Corridor due to lower ridership Less frequent service than East Corridor High cost to electrify corridor due to length DMUs are $230K/year less expensive to operate than EMUs

11. North Metro Corridor

12. Results of Analysis: North Metro Corridor Both EMUs and DMUs are cost-competitive DMUs are more cost-effective EMU: - $37.89M, DMU: - $84.16M Shorter train lengths than East Corridor Less frequent service than East Corridor Station spacing and corridor length are appropriate for either EMU or DMU

13. Next Steps Northwest & North Metro Rail: Northwest Rail: Commuter rail vehicle technology cost analysis will be input into the EA evaluation North Metro: Commuter rail vehicle technology cost analysis will be presented as part of the scoping meetings and analyzed as part of the EIS

14. Multiple Vehicle Technologies for FasTracks Maintenance Facility: One facility can accommodate both vehicle types Minor increase in size Requires track electrification in yards and building (included in EMU costs) Requires fueling facility (included in DMU costs) Requires spare parts for two technologies

15. 30 Year Capital & O&M Costs* for EMU and DMU Compared to LHC (Original FasTracks Plan) (Inflated Dollars) Impact of Higher Energy Prices Assumptions* Diesel: $3.5/gallon Electricity: $0.10/kWh Inflation: 3%/year Each corridor analyzed independently (no savings for same technology in multiple corridors) EMUDMU East Corridor- $ 312.44 M- $178.69 M North Metro- $99.25M- $108.29 M Northwest Rail- $58.43 M - $37.81 M

16. 30 Year Capital & O&M Costs* for EMU and DMU Compared to LHC (Original FasTracks Plan) (Inflated Dollars) Impact of Low Energy Prices, No Inflation Assumptions* Diesel: $2.50/gallon Electricity: $0.085/kWh Inflation: 0%/year Each corridor analyzed independently (no savings for same technology in multiple corridors) EMUDMU East Corridor- $ 86.39 M- $79.71 M North Metro+ $0.15M- $44.10 M Northwest Rail+ $60.27 M - $2.44 M
