A depot would need to be constructed, which would require $2.5million in land and $7.5 million in construction costs. Annual operating and maintenance costs (O&M) for the facility would be $150,000, and personnel costs would be an additional $110,000. Other assorted costs would be born by the railroad and federal authorities. Annual benefits (B) of the rail service are estimated as listed: $120,000 for Railroad annual payments, $25,000 for Rail tax charged to passengers, $20,000 for Convenience benefits to local residents, and $12,000 for Additional tourism dollars for Metro. Apply the B-C ratio method, with a MARR of 8% per year and 20 year study period, to determine if the rail service should be established. a. BC ratio=2.12, good project b.
